The provided FDA 510(k) clearance letter and summary for K243082 details the acceptance criteria and the study that proves the device meets these criteria.
Here's a breakdown of the requested information:
1. Table of Acceptance Criteria and Reported Device Performance
The primary acceptance criteria for the Infrared Thermometer are derived from the performance standard ISO 80601-2-56 for clinical thermometers.
| Acceptance Criteria (from ISO 80601-2-56) | Reported Device Performance |
|---|---|
| Accuracy (Clinical Test): | Complied with ISO 80601-2-56. |
| - For forehead/ear temperature measurement | Details on specific accuracy ranges not explicitly stated in this document but confirmed compliance with the standard. |
Note: The 510(k) summary only generally states compliance with ISO 80601-2-56 for clinical performance. It does not explicitly list the detailed accuracy limits from the standard (e.g., ±0.2°C within a certain range) and then report the device's measured accuracy against those specific limits in a direct table format within the provided text, but rather confirms overall compliance. The "Measuring accuracy" in the comparison table is for the device's technical specification, not necessarily a direct clinical accuracy result from the ISO 80601-2-56 study itself.
2. Sample Size Used for the Test Set and Data Provenance
- Sample Size for Test Set: A minimum of 150 subjects.
- Data Provenance: The document does not explicitly state the country of origin. It also doesn't specify if the data was retrospective or prospective, though clinical performance testing as described ("The testing is conducted pre ISO 80601-2-56") usually implies prospective data collection for the purpose of demonstrating performance.
3. Number of Experts Used to Establish Ground Truth and Qualifications
This information is not provided in the document. For a thermometer, ground truth is typically established by comparative measurements against a highly accurate reference thermometer, rather than expert consensus on subjective interpretations.
4. Adjudication Method
This information is not applicable/provided as the ground truth for thermometer accuracy is established by a reference device, not by expert interpretation requiring adjudication.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
An MRMC comparative effectiveness study was not done. This type of study is relevant for diagnostic devices where human readers interpret and classify images or data, often with and without AI assistance to measure the AI's impact on human performance. For a thermometer, the output is a direct numerical measurement, so this type of study is not applicable.
6. Standalone Performance Study
Yes, a standalone performance study was done. The document states:
"The testing is conducted pre ISO 80601-2-56 Particular requirements for basic safety and essential performance of clinical thermometers for body temperature measurement. This performance test consists of a minimum of 150 subjects... The test result demonstrated the clinical performance of the subject device complied with the requirement of standard ISO 80601-2-56."
This clinical performance test on subjects directly evaluates the Infrared Thermometer (algorithm/device only) against a reference, thus constituting a standalone performance study.
7. Type of Ground Truth Used
The type of ground truth used is comparative measurement against a reference standard. While not explicitly stated, the ISO 80601-2-56 standard for clinical thermometers mandates comparison of the device's temperature readings against a highly accurate reference thermometer simultaneously or sequentially on human subjects.
8. Sample Size for the Training Set
The document does not provide information on a training set sample size. This device is an infrared thermometer, which typically relies on established physical principles (infrared radiation detection) and calibration rather than a machine learning model that requires a "training set" in the conventional sense of AI. Calibration and functional testing are usually performed at the manufacturing stage.
9. How the Ground Truth for the Training Set Was Established
As noted above, a separate "training set" and associated ground truth establishment (in the AI/machine learning sense) are not applicable to this type of device according to the provided documentation. The device's accuracy is established through calibration and verified through clinical testing against a reference standard.

2. Sample Size Used for the Test Set and Data Provenance
- Sample Size (Clinical Test): 200 subjects.
- Age Group A (0 up to 3 months): 50 subjects
- Age Group B (3 months to one year): 50 subjects
- Age Group C (older than one year to five years): 50 subjects
- Age Group D (older than five years): 50 subjects
- Data Provenance: The document does not explicitly state the country of origin or whether the data was retrospective or prospective. However, clinical accuracy testing is typically prospective, as it involves taking real-time measurements in a controlled study. Given the manufacturer's location (China), the study likely took place in China.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
The document does not provide details on the number or qualifications of experts used to establish ground truth for temperature measurements in the clinical study. For infrared thermometers, the "ground truth" (reference temperature) is typically established using a highly accurate, calibrated clinical thermometer (e.g., a rectal thermometer for core body temperature) as per standards like ISO 80601-2-56 and ASTM E1965-98. The experts involved would typically be clinical staff (nurses, physicians) following a strict protocol for reference temperature measurement.
4. Adjudication Method (for the test set)
The document does not detail an adjudication method. For clinical thermometer accuracy studies, adjudication is generally not a separate process as the reference standard measurement (ground truth) is considered definitive. The "test" is how closely the device's reading matches this established reference, not a subjective interpretation.
5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
No, a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not done. This device is an infrared thermometer, not an AI-powered diagnostic imaging tool. Therefore, the concept of "human readers improving with AI assistance" is not applicable here.
6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) was done
Yes, the primary clinical accuracy and performance testing of the Infrared Thermometer Model YJ600, as described, is a standalone (algorithm only) performance assessment. The device measures and displays temperature without human interpretation of the measurement itself. While a human operates the device, the core performance being evaluated is the device's ability to accurately measure temperature independently of human judgment.
7. The Type of Ground Truth Used
The ground truth used for the clinical accuracy test is the reference body temperature measurement obtained through methods specified in ISO 80601-2-56 and ASTM E1965-98. These standards typically require comparative measurements against a highly accurate reference thermometer (e.g., an electronic thermometer measuring core body temperature, often rectal, or a precise oral measurement) to assess the deviation and repeatability of the infrared thermometer. The document specifically states "clinical repeatability" and that it "meets the clinical repeatability requirement," implying comparison against a gold standard in a clinical setting.
8. The Sample Size for the Training Set
The document does not mention or specify a "training set" because this device is a physical medical device (thermometer) and not an AI/Machine Learning algorithm that requires a separate training dataset. Its performance is based on its hardware and firmware, which are designed and then validated through testing.
9. How the Ground Truth for the Training Set was Established
As there is no "training set" in the context of an AI/ML algorithm for this device, the question of how its ground truth was established is not applicable. The device's design implicitly relies on established physics principles of infrared radiation and measurement, and its accuracy is validated against clinical ground truth during performance testing.

The Infrared thermometer is intended to measure human body temperature of people over three months old from the eardrum or forehead. It is indicated to be used in homecare and healthcare environments.
The Infrared thermometer is a handheld device, which can measure human body's temperature either via the eardrum or the forehead for clinical or home use. The results can be displayed on LCD and can also be transmitted to a non-device APP to record and display through Bluetooth.
There are two models AOJ-20A and AOJ-20Y. Both models share the same construction except differences on product enclosure,PCB layout and button designs.
The provided text describes a 510(k) premarket notification for an Infrared Thermometer (AOJ-20A; AOJ-20Y). It details the device, its intended use, and the non-clinical testing performed to establish substantial equivalence to predicate devices.
However, the document does not contain the level of detail typically found in a clinical study report or a more comprehensive validation plan. Specifically, it lacks:
- Explicit acceptance criteria in a tabular format with corresponding performance results.
- Specific sample sizes for test sets beyond general statements of testing being conducted.
- Data provenance (country, retrospective/prospective) for clinical data.
- Number and qualifications of experts for ground truth.
- Adjudication methods.
- Information on Multi-Reader Multi-Case (MRMC) comparative effectiveness studies.
- Standalone algorithm performance details.
- Specific details on the type of ground truth (e.g., pathology, outcomes data) beyond "performance effectiveness."
- Training set sample size and ground truth establishment for training.
The document primarily focuses on non-clinical performance data to support the substantial equivalence claim, rather than a clinical study demonstrating acceptance criteria met in a real-world setting with human subjects. The tests mentioned are:
- Biocompatibility testing: Cytotoxicity, Skin Sensitization, Skin Irritation per ISO 10993-1.
- Electrical safety and electromagnetic compatibility (EMC): Compliance with IEC 60601-1, IEC 60601-1-11, and IEC 60601-1-2.

The information on "study that proves the device meets the acceptance criteria" is limited to the types of non-clinical tests conducted.
Therefore, direct answers to many of your questions cannot be provided from the given document as it does not contain clinical study data or a detailed validation report with specific performance metrics against acceptance thresholds.
Based on the provided text, here is what can be inferred and what is explicitly stated:
1. A table of acceptance criteria and the reported device performance
The document references compliance with ISO 80601-2-56 for "performance effectiveness" in bench testing. This standard likely specifies accuracy and precision requirements for clinical thermometers. However, the specific numerical acceptance criteria (e.g., ±0.2°C) and the actual measured performance values of the device against these criteria are not provided in this summary.
Inferred/General:
| Acceptance Criteria (Standard) | Reported Device Performance |
|---|---|
| Performance Effectiveness | Complies with ISO 80601-2-56 (details not provided) |
| Biocompatibility | Passes Cytotoxicity, Skin Sensitization, Skin Irritation per ISO 10993-1 |
| Electrical Safety & EMC | Complies with IEC 60601-1, IEC 60601-1-11, IEC 60601-1-2 |
| Software V&V | Testing conducted, documentation provided per FDA guidance for "Basic" level device software |
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
- Sample size for test set: Not specified. The document states "Bench testing was conducted on the thermometer device, consisting of all the system." This suggests testing of the physical devices, but no numerical sample count (e.g., number of thermometers tested, number of measurements taken) is given.
- Data provenance: Not specified. The tests are non-clinical bench and lab tests, not clinical human subject data.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
- Not applicable as the testing described is non-clinical/bench testing, not involving human expert interpretation for ground truth.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
- Not applicable.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
- Not applicable. This is a medical device (thermometer), not an AI imaging or diagnostic algorithm used by human readers.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
- The document describes the performance of the device itself (sensor, electronics, software) in a standalone manner via bench testing, but not an "algorithm only" in the sense of a standalone AI model. The device's function is temperature measurement.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
- For "performance effectiveness," the ground truth (or reference standard) would typically be calibrated reference thermometers or temperature sources compliant with the ISO standard used for test and measurement, not clinical outcomes or expert consensus.
- For biocompatibility, the ground truth is the chemical and biological assays.
- For electrical safety and EMC, the ground truth is the measurement against standard limits using appropriate test equipment.
8. The sample size for the training set
- Not applicable, as this is a traditional medical device (thermometer), not an AI/machine learning model requiring a training set for its core function. The "software verification and validation testing" refers to standard software engineering practices, not machine learning model training.
9. How the ground truth for the training set was established
- Not applicable for the same reasons as point 8.

| ±0.3°C outside this temperature range | |
| Measurement Time | ≤3 seconds |
| Measurement Distance | 2-5 cm |
Note: The document states that the device's accuracy requirements meet ASTM E1965-98. The specific ASTM E1965-98 requirements for measurement range, accuracy, measurement time, and measurement distance are not explicitly detailed in the provided text beyond what's shown for the device's performance. The table above uses the device's reported performance as the "reported device performance" and implies these meet the ASTM E 1965-98 criteria because the document explicitly states compliance.
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
- Sample size for clinical test set: 169 subjects.
- Data Provenance: The document does not specify the country of origin. The test was a "clinical test" which implies a prospective study.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
This information is not provided in the document. The document only mentions "clinical tests were conducted" and that the "clinical performance of the subject device complied with the requirement of ASTM E1965-98 (2016)." It does not describe the method or personnel used to establish the ground truth (reference temperature).
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
This information is not provided in the document.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
This is an Infrared Thermometer. The document describes clinical tests for device accuracy, not a comparative effectiveness study involving human readers or AI assistance. Therefore, no MRMC comparative effectiveness study was done in the context of human readers improving with or without AI.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done
Yes, a standalone performance study was done for the device. The "clinical tests" described in section 8 were conducted on the Infrared Thermometer (Model: IR8807) itself, evaluating its direct measurement performance against a ground truth (implied by compliance with ASTM E1965-98 for clinical accuracy). This assesses the algorithm/device's performance without human interpretation or intervention in the measurement process beyond standard use.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
The document does not explicitly state the type of ground truth used. However, given that it's a clinical thermometer study and states compliance with ASTM E1965-98, the ground truth would most likely be a reference clinical thermometer (e.g., a highly accurate rectal, oral, or tympanic thermometer, depending on the standard's protocol for correlating to forehead temperature) used simultaneously or sequentially with the test device.
8. The sample size for the training set
This device is a physical thermometer, not an AI/ML model that typically requires a "training set." The concept of a training set is not applicable to this device.
9. How the ground truth for the training set was established
As the concept of a training set is not applicable to this device, this question is not relevant.

The TRULYL Infrared thermometer TET-351 is intended for the intermittent measurement of human body temperature from the auditory canal and from the forehead for people of all ages used in the home setting. The non-contact thermometer detects infrared heat from the forehead at distance of about 1-2cm.
The TRULYL Infrared thermometer TET-351 is a hand-held, battery powered device designed to measure the body temperature through receiving infrared energy radiation via the ear canal or forehead. The thermometer has the capability to measure temperature via forehead temperature mode or ear temperature mode, and the temperature is directly shown on the LCD display. The results measured by TET-351 can also be transmitted to APP to record and display through Bluetooth.
This is an infrared thermometer (TET-351) that measures human body temperature from the auditory canal and forehead. The device is intended for home use for people of all ages.
Here's an analysis of the provided information regarding acceptance criteria and the study that proves the device meets them:
1. Table of Acceptance Criteria and Reported Device Performance
The acceptance criteria are primarily derived from the standard ASTM E1965-98 (Reapproved 2016) Standard Specification for Infrared Thermometers for Intermittent Determination of Patient Temperature. While the document states that the clinical study demonstrated compliance, it does not explicitly list the specific numerical acceptance criteria (e.g., accuracy limits) from ASTM E1965-98 within the provided text, nor does it provide detailed numerical results for the device's performance against those criteria beyond a general statement of compliance.
However, the comparison table with the predicate device does offer some insight into the accuracy specification, which would likely be the basis of the acceptance criteria:
| Feature | Predicate Device (K190873) Accuracy | TET-351 (Subject Device) Accuracy | Note |
|---|---|---|---|
| Accuracy | Ear/Forehead mode: ±0.2°C (0.4°F) during 35.5°C ~ 42.0°C (95.9°F ~ 107.6°F) at 15°C | Ear/Forehead mode: ±0.2°C (0.4°F) (Outside 34~42°C (93.2°F ~ 107.6°F) measurement range, accuracy ±0.3°C (0.5°F)). | Different |
Note: The "Different" note here implies that while the general accuracy ranges are similar, there might be slight variations in the specified temperature ranges where the higher accuracy applies. The report states that the clinical study demonstrated compliance with ASTM E1965-98 (Reapproved 2016), which would inherently define the specific acceptance criteria for accuracy.
2. Sample Size Used for the Test Set and Data Provenance
- Sample Size for Test Set: A minimum of 150 subjects.
- 1/3 children
- 1/3 adults
- The remaining 1/3 (implicitly infants) are not explicitly stated but are covered by the age categories: "Infants---newborn to one year; Children--- greater than one to five years; Adults--- greater than five years old."
- Data Provenance: The document does not explicitly state the country of origin of the data. It refers to "This clinical study" without specifying the location.
- Retrospective or Prospective: Not explicitly stated, but the description "This clinical study is a randomization, simple blind homologous control, pairing design of clinical investigation" strongly suggests a prospective study.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications
This information is not provided in the document. The study involves measuring patient temperature, which typically involves comparing the device's readings against a highly accurate reference thermometer (e.g., rectal or oral core temperature measurement, depending on the standard). The role of "experts" as ground truth adjudicators in the sense of image interpretation is not directly applicable here.
4. Adjudication Method for the Test Set
This information is not explicitly provided in the context of "adjudication" as it might apply to subjective assessments. For temperature measurement studies, the ground truth is typically established by measurements from a validated reference device, not by expert consensus or adjudication. The study design is described as "randomization, simple blind homologous control, pairing design," but this refers to the overall study methodology rather than a specific ground truth adjudication process.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
A Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not conducted in the traditional sense of evaluating human readers with and without AI assistance, as this device is a standalone thermometer, not an AI-powered diagnostic imaging tool.
6. Standalone (Algorithm Only) Performance
A standalone performance study was done. The entire clinical study for the Infrared Thermometer TET-351 is a standalone performance evaluation, as it assesses the accuracy of the device itself (algorithm + hardware) against a reference standard in patients.
7. Type of Ground Truth Used
The ground truth implicitly used for clinical accuracy assessment for thermometers is a reference temperature measurement obtained from a highly accurate clinical reference device (e.g., glass thermometer, electronic thermometer, or other gold-standard method for core body temperature measurement). The standard ASTM E1965-98 outlines how these reference measurements should be obtained. The document does not explicitly state the specific reference method used, but it's central to the standard's methodology.
8. Sample Size for the Training Set
This information is not provided. As this is a medical device and not an AI/ML imaging algorithm that requires a separate training set, the concept of a "training set" in this context is not directly applicable for the device's primary function of temperature measurement. Any internal calibration or algorithm development would have been done prior to the clinical validation.
9. How the Ground Truth for the Training Set Was Established
Given that this is an infrared thermometer and not an AI/ML imaging algorithm, a separate "training set" with established ground truth in the AI sense is not applicable. The device's underlying physics and calibration would be based on established temperature measurement principles.

The Infrared thermometer is intended to measure human body temperature of people over three months old from the eardrum or forehead. It is indicated to be used in homecare and healthcare environments.
The AOJ-20 series Infrared thermometer is a handheld device, which can measure human body's temperature either via the eardrum or the forehead, for clinical or home use. The results can be displayed on LCD. The device operates in adjusted mode, and the reference body site of output temperature is oral. The measurement distance for forehead mode is 0 cm ~ 3 cm. The thermometers are powered by AAA 1.5V×2 alkaline batteries. A thermopile sensor is employed to detect or monitor the infrared thermal energy emitted from the eardrum or the surface of the skin of forehead, which is converted to the equivalent oral temperature with the unit of °C or ºF. All the models share the similar design and the same critical components. The major differences include: - Mechanical changes and the corresponding hardware adjustment happened to AOJ-20A, AOJ-20B, AOJ-20C, AOJ-20D, AOJ-20E, AOJ-20F, AOJ-20H, AOJ-20M, AOJ-20T, AOJ-20R and AOJ-20Y - In the measurement function, two measurement modes are distinguished between children and adults for AOJ-20B and AOJ-20E.
The provided text describes the regulatory clearance of an Infrared Thermometer (AOJ-20 series) and includes detailed performance testing against acceptance criteria. Here's a breakdown of the requested information:
1. Table of Acceptance Criteria and Reported Device Performance
The device is an Infrared Thermometer, and its primary performance criterion is accuracy. The relevant standard for accuracy is ISO 80601-2-56.
| Acceptance Criteria (from ISO 80601-2-56) | Reported Device Performance |
|---|---|
| Accuracy: ±0.2°C (±0.4°F) | ±0.2°C (±0.4°F) |
| Biocompatibility: No cytotoxicity | No potential cytotoxicity |
| Biocompatibility: No sensitization | No sensitization observed |
| Biocompatibility: No irritation | Negligible irritation |
| Electrical Safety & EMC: Compliance with specific IEC standards (60601-1, 60601-1-11, 60601-1-2) | Device complies with specified IEC standards |
| Software Verification & Validation: Software functions meet requirements | Test results demonstrated software functions met requirements |
| Minimum Subject Numbers for Clinical Accuracy Validation (ISO 80601-2-56 Section 201.102) | All models met minimum subject number requirements for each age group (refer to table in source for specific counts) |
The text explicitly states: "The system complies with the ISO 80601-2-56 Medical electrical equipment — Part 2-56: Particular requirements for basic safety and essential performance of clinical thermometers for body temperature measurement for performance effectiveness." and "Clinical accuracy validation was carried out on people over three month indicated in the instructions for use. The number of subjects in each age group met the minimum number requirements."
2. Sample Size Used for the Test Set and Data Provenance
The "test set" in this context refers to the clinical study subjects for accuracy validation.
- Sample Size: The sample sizes vary per model, but generally around 135-138 subjects per model. The specific breakdown is provided in the table:
- AOJ-20A: 138 subjects
- AOJ-20B: 136 subjects
- AOJ-20C: 137 subjects
- AOJ-20D: 138 subjects
- AOJ-20E: 137 subjects
- AOJ-20F: 137 subjects
- AOJ-20H: 135 subjects
- AOJ-20M: 137 subjects
- AOJ-20T: 137 subjects
- AOJ-20R: 137 subjects
- AOJ-20Y: 137 subjects
- Data Provenance: The document does not specify the country of origin for the clinical data. It also does not explicitly state whether the study was retrospective or prospective, but clinical accuracy validation per ISO standards is typically done in a prospective manner.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
This information is not provided in the given document. For clinical thermometers, ground truth for body temperature is typically established using a highly accurate reference thermometer (e.g., rectal or oral thermometer depending on the standard's requirements for reference body site), not necessarily by human experts.
4. Adjudication Method for the Test Set
This information is not provided in the given document. Adjudication methods like 2+1 or 3+1 are more common in studies involving subjective assessments (e.g., image interpretation by radiologists), which is not directly applicable to a thermometer's clinical accuracy validation where objective measurements against a reference are typically performed.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done
No, a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not explicitly mentioned or performed. This type of study is more relevant for diagnostic aids where human interpretation is involved. The document describes clinical accuracy validation of the device itself.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was done
The device is an Infrared Thermometer, which is a standalone measurement device. Its performance is inherently standalone. There is no "algorithm only" component separate from human interaction, as a human user operates the device to take a temperature reading. The clinical and bench testing described assess this standalone performance.
7. The Type of Ground Truth Used
The ground truth used for clinical accuracy validation of a thermometer is typically based on a reference body temperature measurement obtained by a highly accurate, calibrated reference thermometer (e.g., a specific type of oral or rectal thermometer). The document states the device "operates in adjusted mode, and the reference body site of output temperature is oral," implying oral temperature is the reference for adjusted readings. The study was conducted "per Section 201.102 of ISO 80601-2-56," which would define the exact method for establishing ground truth.
8. The Sample Size for the Training Set
This information is not applicable and therefore not provided. Infrared thermometers are hardware devices with embedded algorithms, but they are not typically "trained" on large datasets of temperature readings in the way AI/ML models are. The device relies on physical principles of infrared detection and calibrated conversion algorithms, not a training set in the AI sense.
9. How the Ground Truth for the Training Set Was Established
This information is not applicable as there is no mention of a "training set" in the context of this infrared thermometer. The device's internal algorithms and calibrations are developed and verified through engineering principles and bench testing, not machine learning training on a ground truth dataset.

- Low battery indication, and auto power-off
Here's a breakdown of the acceptance criteria and study details for the Infrared Thermometer (Models: Y20001, Y20002), based on the provided FDA 510(k) summary:
1. Table of Acceptance Criteria and Reported Device Performance
The core performance acceptance criteria for this medical device revolve around its accuracy in measuring body temperature. These are primarily derived from recognized international and national standards.
| Acceptance Criteria | Reported Device Performance | Reference Standard(s) |
|---|---|---|
| Measurement Range | 34.0°C to 42.9°C (93.2°F to 109.2°F) | ISO 80601-2-56:2017, ASTM E1965-98 (2016) |
| Accuracy | ± 0.3°C / 0.5°F | ISO 80601-2-56:2017, ASTM E1965-98 (2016) |
| Display Resolution | 0.1°C / 0.1°F | ISO 80601-2-56:2017, ASTM E1965-98 (2016) |
| Clinical Accuracy | Complied with ISO 80601-2-56:2017+AMD2018 requirements | ISO 80601-2-56:2017+AMD2018 |
| Electrical Safety | Complied with IEC 60601-1:2005+AMD 1:2012, IEC 60601-1-11:2015 | IEC 60601-1, IEC 60601-1-11 |
| Electromagnetic Compatibility (EMC) | Complied with IEC 60601-1-2:2014 | IEC 60601-1-2 |
| Biocompatibility | Non-cytotoxic, non-sensitizing, non-irritating | ISO 10993-5, ISO 10993-10, ISO 10993-23 |
Note on Accuracy: While the table states "± 0.3°C / 0.5°F", the comparison table (Note 4) mentions the subject device's accuracy being wider than the predicate within the range of 36.0°C - 39.0°C. However, the overall claim is that it still meets the performance standards based on the test reports. This implies that the ±0.3°C/0.5°F stated is the overarching acceptable tolerance.
2. Sample Size Used for the Test Set and Data Provenance
- Sample Size: Each clinical study evaluated 150 subjects.
- Data Provenance: Not explicitly stated regarding the country of origin of the data. The studies were designed to evaluate subjects across specific age groups and a portion of fever patients, suggesting it was a prospective study conducted for regulatory submission.
The subjects were divided into three age groups with 50 subjects in each group:
* Infants: two months to one year
* Children: greater than one to five years
* Adults: greater than five years old
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications
The document does not explicitly state the number of experts or their specific qualifications (e.g., "radiologist with 10 years of experience") used to establish the ground truth for the clinical accuracy test. However, for clinical thermometers, the "ground truth" (reference temperature) is typically obtained using a highly accurate, calibrated reference thermometer according to the specified standard (ISO 80601-2-56). The measurement itself, and hence the ground truth, relies on the precision of the reference device and adherence to standardized measurement protocols, rather than expert interpretation of an image or similar data.
4. Adjudication Method for the Test Set
Not applicable/Not mentioned. For a clinical thermometer's accuracy assessment, adjudication methods like 2+1 or 3+1 are typically used for subjective evaluations (e.g., image interpretation). Here, the comparison is quantitative: the device's reading versus a reference standard's reading.
5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study was done
No, an MRMC comparative effectiveness study was not done. This type of study is more relevant for diagnostic imaging where human readers interpret results, and the AI's impact on their performance is being evaluated. For a thermometer, the performance is measured purely on its accuracy against a known standard.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was done
Yes, the primary clinical accuracy testing described is a standalone performance test of the device. The "clinical accuracy testing" evaluates the device's ability to measure human body temperature accurately as per ISO 80601-2-56 requirements, without human intervention affecting the measurement result itself. It compares the thermometer's reading directly to a reference method, acting as an algorithm-only performance assessment in the context of a medical device that outputs a direct measurement.
7. The Type of Ground Truth Used
The ground truth for the clinical accuracy test was established by comparing the infrared thermometer's readings to reference temperature measurements obtained according to the requirements of ISO 80601-2-56:2017. This typically involves a highly accurate, calibrated reference thermometer measuring core body temperature from a different site or a more invasive method, or using a specified (e.g., oral or rectal) reference thermometer, against which the non-contact device is compared. This is a type of objective measurement standard ground truth.
8. The Sample Size for the Training Set
The document does not provide any information about a training set. This device is a measurement tool, not an AI/ML algorithm that requires a separate training data set for model development. The performance is based on the physical design, sensors, and firmware logic, which are validated through bench and clinical testing.
9. How the Ground Truth for the Training Set Was Established
Not applicable, as no training set is mentioned or implied for this type of device. The device's operational parameters and calibration would be established through engineering design and bench testing, not through supervised learning with a specific "training set" in the AI/ML sense.

The Infrared thermometer is a multi-function infrared thermometer intended for the intermittent measurement of human body temperature by Ear canal or by the center of forehead(non-contact type) for people of all ages.
Not Found
The provided text concerns the FDA 510(k) clearance for an "Infrared thermometer" (K221211). It does not describe:
- Acceptance criteria for an AI/ML device. This document is for a physical medical device (an infrared thermometer), not a software or AI-driven diagnostic tool.
- A study proving the device meets acceptance criteria. The letter states that the device is "substantially equivalent" to legally marketed predicate devices, which is the basis for 510(k) clearance, rather than detailing a specific performance study against defined acceptance criteria.
Therefore, I cannot extract the information required by your request about acceptance criteria and a study proving an AI/ML device meets them, as this document is not about such a device or study.
The request specifically asks for information related to AI/ML device studies (e.g., sample sizes for test/training sets, expert ground truth, MRMC studies, standalone performance). This information is entirely absent for a simple infrared thermometer.
