2. Sample size used for the test set and the data provenance:
- The document does not explicitly state the sample sizes (e.g., number of gloves) used for each specific non-clinical test. These sample sizes would be specified within the methodologies of the referenced ASTM and ISO standards.
- Data Provenance: The testing was conducted by or on behalf of Guangdong Kingfa Sci.&Tech. Co., Ltd., based in China. The data is from non-clinical laboratory testing, not human subjects, and is inherently retrospective as it was conducted prior to this submission.
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):
- Not applicable. For this type of device, "ground truth" is established by the physical and chemical properties measured against the objective metrics defined in the ASTM and ISO standards, using calibrated equipment and standard laboratory procedures. It does not involve human expert interpretation or consensus comparable to image-based medical device studies.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:
- Not applicable. Adjudication methods are relevant for human-interpretable data where multiple readers might have differing opinions (e.g., medical image interpretation). This submission relies on objective laboratory test results.
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. MRMC studies are used for evaluating human performance, typically involving AI assistance in diagnostic tasks. This device is an examination glove, not an AI-enabled diagnostic tool. No clinical study was performed.
6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done:
- Not applicable. This device does not have an "algorithm" or standalone AI component. Its performance is measured directly through physical and chemical testing.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
- The "ground truth" for this device is based on objective measurements against established engineering and biocompatibility standards. For example, tensile strength measured in MPa, hole detection based on water leak AQL, residual powder in mg/glove, protein content in µg/dm², and ISO 10993 series for biological responses (irritation, sensitization, systemic toxicity) are the "ground truth" metrics.
8. The sample size for the training set:
- Not applicable. This is a physical product, not a machine learning model, so there is no "training set."
9. How the ground truth for the training set was established:
- Not applicable due to the absence of a training set.

Study Details (Applicable to this Device Type)
Given this is a 510(k) for examination gloves, the "study" is a series of non-clinical, laboratory tests performed according to specific ASTM and ISO standards, rather than a clinical trial or an AI algorithm performance study.
2. Sample Size Used for the Test Set and Data Provenance:
The document does not explicitly state the sample sizes for each specific test (e.g., how many gloves were tested for length, width, or tensile strength). However, it implies that standard testing methodologies as defined by ASTM and ISO were followed. These standards usually specify the number of samples required for each test. The data provenance is from JR Engineering & Medical Technologies (M) SDN.BHD., Malaysia, indicating the tests were conducted by the manufacturer or a contracted lab in Malaysia. The data is non-clinical performance data, reported as part of a premarket notification.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications:
Not applicable. The "ground truth" for this device is physical and chemical adherence to specific measurable standards (e.g., a glove is X mm long, has Y tensile strength), not a diagnostic interpretation requiring expert medical opinion. The standards themselves, like ASTM D3578-2019, serve as the "ground truth" for performance.
4. Adjudication Method for the Test Set:
Not applicable. This is not a human-interpreted diagnostic task requiring adjudication. The tests are objective measurements against defined criteria.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done:
No, this was not done. MRMC studies are typically for diagnostic imaging devices or algorithms where the performance of human readers (with and without AI assistance) on clinical cases is evaluated. This device is an examination glove.
6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) was done:
No, this is not an AI algorithm. Its performance is measured through physical and chemical properties.
7. The Type of Ground Truth Used:
The ground truth used is objective engineering and material science standards (e.g., ASTM D3578-2019, ASTM D5151-2019, ASTM D6124-06, ASTM D5712-95, ISO 10993 series). These are internationally recognized standards for manufacturing and safety.
8. The Sample Size for the Training Set:
Not applicable. This is not an AI device trained on a dataset. The "training" for such a device would be the manufacturing process development and quality control to ensure consistency.
9. How the Ground Truth for the Training Set was Established:
Not applicable, as it's not an AI training set. The "ground truth" for manufacturing would be the specifications and quality control procedures adherence to ensure gloves meet the physical and chemical standards.

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 information is not applicable. This document describes an examination glove, not an AI-assisted diagnostic device.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done
This information is not applicable. This document describes an examination glove, not an AI-assisted diagnostic device.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
The "ground truth" for the performance of the Disposable Medical Rubber Examination Gloves is established by:
- International Standards: Primarily ASTM D3578-19 (Standard Specification for Rubber Examination Gloves) for physical properties and dimensions, and various ISO 10993 series standards for biocompatibility (ISO 10993-11 for systemic toxicity, ISO 10993-23 for irritation, ISO 10993-10 for sensitization).
- Objective Test Methods: Laboratory tests as described (e.g., steel ruler and thickness measurement apparatus for dimensions, dumbbell/straight section specimens for physical properties, water leakage for holes, gravimetric methods for residual powder, modified Lowry Method for protein content).
- Animal Models: For biocompatibility tests (ICR mice for acute systemic toxicity, rabbits for skin irritation, guinea pigs for skin sensitization).
8. The sample size for the training set
This information is not applicable. The device is a physical product (examination gloves), not a software algorithm that requires a training set. The performance is based on manufacturing and testing against established standards.
9. How the ground truth for the training set was established
This information is not applicable for the same reason as point 8.

The proposed device is made of natural rubber latex and meet all the current specifications listed under the ASTM Specification D3578-19, Standard Specification for Rubber Examination Gloves. The principal operation and mechanism of this device is to prevent contamination between patient and examiner and this principle is achieved through testing of barrier, physical properties and other testing stated in the performance data. This device is provided non-sterile, in sizes XS, S, M, L and XL, natural white color, powder free, and the shelf life is 3 years.
The provided text describes the 510(k) premarket notification for a medical device: "Single-use medical latex examination gloves (LG100)". This document is not for an AI/ML-based medical device. Therefore, the questions related to AI/ML device testing (such as sample size for test/training sets, data provenance, number of experts for ground truth, adjudication methods, MRMC studies, standalone performance, etc.) are not applicable to this submission.
The document focuses on demonstrating substantial equivalence to a predicate device (K214017) through non-clinical performance testing against established ASTM and ISO standards for examination gloves.
Here's the relevant information based on the provided text, primarily focusing on the acceptance criteria and performance of the glove:
Acceptance Criteria and Device Performance for Single-use Medical Latex Examination Gloves (LG100)
This device is not an AI/ML system, but rather a physical medical device (examination gloves). Therefore, the acceptance criteria and study data relate to physical, chemical, and biological properties of the gloves, not algorithmic performance.
1. A table of acceptance criteria and the reported device performance:
Test Methodology | Purpose | Acceptance Criteria | Reported Performance |
---|---|---|---|
ASTM D3578-19 | Physical Dimension | The actual measured dimension of the gloves shall meet the stated tolerance specified in Table 2 of the ASTM D3578-19: |
