2. Sample Size Used for the Test Set and Data Provenance
The document does not specify the exact sample sizes (e.g., number of gowns or material samples) used for each specific non-clinical test. It only states that the tests were performed "under the test conditions" for biocompatibility and that results for physical tests (e.g., breaking strength, tearing strength) are given as means and standard deviations, implying multiple samples were tested.
The data provenance is from non-clinical laboratory testing. The document does not explicitly state the country of origin of the data or whether it was retrospective or prospective, beyond acknowledging that these are test results supporting a 510(k) submission. Given it's a 510(k) submission to the US FDA from a Taiwanese company (Copioumed International Inc.), the testing would have been conducted to meet US regulatory requirements, likely in certified labs.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications
This submission is for a physical medical device (isolation gown) and relies entirely on non-clinical laboratory testing against recognized industry standards (ASTM, AAMI, ISO, AATCC, CFR). Therefore:
- No human experts were used to establish ground truth in the context of clinical interpretation (e.g., radiologists for imaging data).
- The "ground truth" is defined by the numerical criteria outlined in the referenced performance standards. The qualifications of the personnel conducting these laboratory tests would be that they are trained and competent in performing the specific standard tests in accredited laboratories. The document does not provide details on these personnel.
4. Adjudication Method for the Test Set
Not applicable. Since the evaluation is based on non-clinical, objective laboratory tests with defined quantitative pass/fail criteria, there is no team of experts adjudicating results in the way one would for clinical data or imaging interpretations. The tests yield objective measurements that are compared against a pre-defined standard's requirements.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done
No. This is a 510(k) submission for an isolation gown, not a software or AI-assisted diagnostic tool. MRMC studies are not relevant for this type of device.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
Yes, in a sense. The "performance" of this device is its physical and chemical barrier properties and material strength. These are assessed in laboratory settings without human intervention in the loop beyond the initial setup and analysis of the test apparatus. The tests are designed to measure the inherent properties of the gown material and construction.
7. The Type of Ground Truth Used
The ground truth used for this device's performance evaluation is based on defined quantitative and qualitative criteria set by recognized consensus standards (e.g., AAMI PB70:2012 for liquid barrier performance, ASTM F739-20 for chemotherapy drug permeation, various ASTM standards for material strength, and ISO 10993 for biocompatibility). These standards specify the methodology and acceptance criteria for demonstrating the device's protective capabilities.
8. The Sample Size for the Training Set
Not applicable. This device is an isolation gown, not an AI/ML-based device that requires a training set. The evaluation is based on physical and chemical testing of the final product.
9. How the Ground Truth for the Training Set Was Established
Not applicable, as there is no training set for this device.

| Sensitization | To evaluate the sensitization property of the gown | Under the conditions of the study, the device is not a sensitizer | Pass |
2. Sample size used for the test set and the data provenance:
- Sample Size:
- For Hydrostatic pressure test and Water impact resistance, the acceptance criteria state "32 of 32 samples pass each location." This implies a sample size of 32 for these specific tests.
- Specific sample sizes for other non-clinical tests (e.g., seam strength, tensile strength, tear strength, lint generation, flammability, biocompatibility) are not explicitly stated in this document beyond the general "sample" or "test sample." However, these types of tests typically involve testing multiple units or specimens to ensure reproducibility and statistical validity according to the referenced standards.
- Data Provenance: The document does not explicitly state the country of origin or whether the studies were retrospective or prospective. Given that the manufacturer is based in China, it is highly probable that the testing was conducted there. All tests described are non-clinical tests, which are typically conducted in a controlled laboratory setting (i.e., not on human subjects), and thus the retrospective/prospective distinction is not applicable in the same way it would be for a clinical trial.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- This information is not applicable as the studies are entirely non-clinical (laboratory-based performance and material property testing). There are no human experts establishing a "ground truth" for diagnostic or clinical interpretation. The "ground truth" for these tests comes from adherence to established international and national standards (e.g., ASTM, ISO, AAMI, AATCC, CPSC CFR) for material properties and barrier performance.
4. Adjudication method for the test set:
- This information is not applicable. Adjudication methods like 2+1 or 3+1 are used in studies involving human interpretation (e.g., image reading) where there might be disagreement among experts. Since these are non-clinical, objective laboratory tests against pre-defined numerical or qualitative criteria, there is no need for expert adjudication.
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, an MRMC comparative effectiveness study was not conducted. This device is a disposable isolation gown, and the submission focuses on its physical and barrier properties, not on an AI-assisted diagnostic or interpretive tool that would involve human readers.
6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done:
- No, a standalone algorithm-only performance study was not conducted. This device is manufactured personal protective equipment (PPE), not software or an AI algorithm. The performance evaluation is based on material and product testing against established engineering and safety standards.
7. The type of ground truth used:
- The "ground truth" for these non-clinical tests is based on established testing standards and regulatory requirements. This includes:
- Material properties: Tensile strength, tear strength, seam strength, lint generation, flammability, all measured against specific ASTM and ISO standards with predefined passing criteria.
- Barrier performance: Hydrostatic pressure and water impact resistance, measured against AAMI PB70:2012 (Level 3) and AATCC standards.
- Biocompatibility: Cytotoxicity, irritation, and sensitization, measured against ISO 10993 standards with "not cytotoxic," "not an irritant," and "not a sensitizer" as the ground truth.
- Shelf-life stability: Demonstrated by meeting all performance requirements after accelerated aging, with the original acceptance criteria serving as the ground truth for stability.
8. The sample size for the training set:
- This information is not applicable as the device is a physical product (disposable isolation gown), not a machine learning model. Therefore, there is no "training set" in the context of AI or algorithms.
9. How the ground truth for the training set was established:
- This information is not applicable for the reason stated above.

- Sample Size for Mechanical/Physical Tests: For most mechanical and physical tests (Seam strength, Breaking strength, Tear strength, Lint and other generation), the results are reported as an "Average result from 10 samples."
- Sample Size for Biocompatibility Tests: Not explicitly stated but generally follows ISO 10993 standards which define sample sizes.
- Data Provenance: The tests were conducted to verify that the proposed device met design specifications. The document does not specify the country of origin of the testing data beyond listing the applicant's address in Xiamen, Fujian, China. The studies are non-clinical (laboratory-based performance and safety tests), not related to patient data, so "retrospective or prospective" does not apply in the typical sense.
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 product is a medical device (isolation gown), not an AI/imaging device requiring expert interpretation for ground truth. The "ground truth" for these tests is established by adherence to recognized international and national standards (e.g., AAMI, ASTM, ISO, CPSC). The experts involved would be laboratory technicians and engineers who are qualified to perform these specific standard tests, but their specific number or qualifications are not detailed in this submission as it's not relevant for this type of device.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Adjudication methods like 2+1 or 3+1 are typically for clinical studies or studies involving human readers/interpreters. This document describes non-clinical laboratory testing of a physical product against established performance standards. Therefore, an adjudication method is not applicable and not mentioned.
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, an MRMC comparative effectiveness study was not done. This device is a disposable isolation gown, not an AI-powered diagnostic or assistive technology that would involve human readers or AI assistance.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
No, a standalone algorithm-only performance study was not done. This is not an algorithmic device. The "standalone" performance here refers to the physical gown's performance against defined standards.

- Not Applicable. This study is a non-clinical performance testing of a physical medical device (isolation gown) against established engineering and material science standards. It does not involve human interpretation of data or diagnostic tasks where expert ground truth would be required. The "ground truth" here is objective measurement against specified criteria.
4. Adjudication Method for the Test Set:
- Not Applicable. As no expert review or human interpretation for diagnosis is involved, there is no adjudication method in the traditional sense. The pass/fail criteria are defined by the testing standards and AQLs.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done:
- No. An MRMC study is relevant for diagnostic devices that involve human interpretation (e.g., radiologists reading images). This submission is for a physical medical device (isolation gown) and does not involve human readers or diagnostic cases.
6. If a Standalone (i.e. algorithm only without human-in-the loop performance) was done:
- Not Applicable. This is not an AI/algorithm-based device. It is a physical product. The performance reported is that of the gown itself, as tested in a lab environment.

Study Proving Device Meets Acceptance Criteria:
The study proving the device meets the acceptance criteria is a series of non-clinical performance tests conducted according to recognized international and national standards.
2. Sample Size Used for the Test Set and Data Provenance:
- Sample Size: The document does not explicitly state the number of individual garments or test specimens used for each particular test (e.g., how many samples were used to calculate the mean Hydrostatic Pressure). However, standard testing protocols for these types of materials and products typically involve multiple specimens to ensure representative results.
- Data Provenance: The device manufacturer is "Wuhan Dymex Healthcare Co., Ltd." in Wuhan, China. The tests are reported to have been performed in accordance with international (ISO, AATCC) and national (ASTM, 16 CFR) standards. The nature of these tests (material properties) suggests they are prospective tests performed on manufactured samples.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications:
- Not Applicable. This is a physical and biological performance testing of a medical device (a gown), not an AI/ML device that generates diagnostic outputs requiring expert interpretation or ground truth labeling (e.g., for images or clinical data). The "ground truth" for these tests comes from the physical/chemical measurements themselves against defined standards.
4. Adjudication Method for the Test Set:
- Not Applicable. As per point 3, there's no need for expert adjudication in these types of performance tests. The results are quantitative measurements against predefined physical/chemical standards.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done:
- No. This is not an AI/ML or diagnostic imaging device. MRMC studies are used to evaluate the impact of a new technology (e.g., AI assistance) on human reader performance, which is not relevant for a surgical isolation gown.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was done:
- Not Applicable. This is not an algorithm or software device. The "standalone" performance here refers to the gown's inherent physical and biological barrier properties, which were measured directly through the non-clinical tests.
7. The Type of Ground Truth Used:
- For physical properties (e.g., hydrostatic pressure, breaking strength, linting), the "ground truth" is established by direct measurement of the material and product characteristics against the specifications outlined in the referenced standards (e.g., ANSI/AAMI PB70, ASTM, AATCC, ISO).
- For biocompatibility (cytotoxicity, sensitization, irritation), the "ground truth" is established through laboratory testing against the criteria specified in ISO 10993 (e.g., cell viability percentages, absence of specific reactions).
8. The Sample Size for the Training Set:
- Not Applicable. There is no "training set" as this is not an AI/ML device that requires machine learning model training.
9. How the Ground Truth for the Training Set Was Established:
- Not Applicable. As per point 8, there is no training set for this type of medical device submission.
