    2. Sample Size Used for the Test Set and Data Provenance

    • Dimension Tests: While specific sample sizes for each dimension measurement aren't individually listed, the watertight test indicates a sample size of 200 pieces for that particular test. For residual powder, the sample size was 5 pieces. For protein content, the sample size was 3 pieces.
    • Data Provenance: The document does not explicitly state the country of origin or whether the data is retrospective or prospective. Given that the manufacturer is Bestsafe Glove Co., LTD. based in Thailand, it is highly likely that the testing was conducted in Thailand or by laboratories compliant with international standards on behalf of the manufacturer. The tests are presented as part of a 510(k) submission, typically involving tests specifically conducted for the device seeking clearance.

    3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications

    • This information is not applicable as the document describes performance testing for medical gloves against established ASTM and ISO standards, not a diagnostic or AI-driven device requiring human expert ground truth for image interpretation or similar tasks. The "ground truth" here is defined by the objective measurement criteria within the specified standards.

    4. Adjudication Method for the Test Set

    • This information is not applicable for the same reasons as point 3. The testing involves objective measurements against established numerical and qualitative criteria defined by the 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. The device is a physical medical glove, not an AI-assisted diagnostic or imaging device. Therefore, no MRMC study or AI assistance comparison was performed.

    6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done

    • This information is not applicable. The device is a physical medical glove, not a software or AI-based device.

    7. The Type of Ground Truth Used

    • The ground truth for the performance of the gloves is established through objective measurements against predefined criteria and thresholds set by international standards for medical gloves, specifically:
      • ASTM D3578-19 (Standard Specification for Rubber Examination Gloves)
      • ASTM D5151-19 (Standard Test Method for Detection of Holes in Medical Gloves)
      • ASTM D6124-06 (Reapproved 2017) (Standard Test Method for Residual Powder on Medical Gloves)
      • ASTM D5712-15 (Standard Test Method for Analysis of Aqueous Extractable Protein in Natural Rubber)
      • ISO 10993-10 (Biological evaluation of medical devices – Part 10: Tests for irritation and skin sensitization)
      • ISO 10993-5 (Biological evaluation of medical devices – Part 5: Tests for in vitro cytotoxicity)
      • ISO 10993-11 (Biological evaluation of medical devices – Part 11: Tests for systemic toxicity)

    8. The Sample Size for the Training Set

    • This information is not applicable. The device 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

    • This information is not applicable for the same reason as point 8.

    Best Glove - Nitrile Powder Free Examination Glove is a disposable device intended for medical purposes that is worn on the examiner's hand to prevent contamination between patient and examiner.

    Device Description

    Blue Nitrile Examination Gloves Powder Free are Class I patient examination gloves bearing the product code Nitrile - LZA (21CFR880.6250). The gloves are made from acrylonitrile-butadiene copolymer dispersion. These gloves are blue in color and are powder free.

    AI/ML Overview

    The provided document describes the acceptance criteria and performance of the BEST GLOVE -NITRILE POWDER FREE EXAMINATION GLOVE as determined through non-clinical testing. It does not involve AI or algorithms, so most of the requested information about studies involving expert Ground Truth, MRMC studies, or multi-reader studies is not applicable.

    Here's the relevant information from the document:

    2. Sample Size Used for the Test Set and Data Provenance

    • Dimension, Thickness, Physical Properties (Tensile Strength, Ultimate Elongation): The sample sizes for these tests are not explicitly stated in the table, but the results are given for different sizes (Small, Medium, Large, Extra Large) of the gloves. The tests were performed against specified ASTM standards (ASTM D6319-19).
    • Watertight Test: A sample size of 200 pieces was used for the watertight test for each size, following a single sampling plan code L for a batch size of 35,001-150,000.
    • Residual Powder: A sample size of 5 pieces was used for the residual powder test for each size.
    • Biocompatibility Tests: The document states "Under the conditions of the study" for these tests, implying specific samples were used for the in-vitro and in-vivo (animal) tests, but exact numbers of samples/animals are not provided in this summary.
    • Data Provenance: The document is a 510(k) Premarket Notification from Thailand (Bestsafe Glove Co., LTD is based in Rayong, Thailand), indicating the tests were likely conducted in or overseen by the manufacturer in Thailand, in accordance with international standards (ASTM, ISO). The studies are non-clinical (laboratory/material testing).

    3. Number of Experts Used to Establish Ground Truth for the Test Set and Their Qualifications

    Not applicable. The document describes material property tests and biocompatibility tests for medical gloves, not a diagnostic device involving expert interpretation or "ground truth" established by experts in a clinical context. The "ground truth" for these tests is defined by the objective measurement criteria within the specified ASTM and ISO standards.

    4. Adjudication Method for the Test Set

    Not applicable. There is no adjudication method described as these are objective performance measurements against established standards for physical and chemical properties of gloves.

    5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

    Not applicable. This device is a medical glove, not an imaging or diagnostic AI tool. Therefore, no MRMC study was performed or is relevant.

    6. Standalone (Algorithm Only) Performance

    Not applicable. This device is a physical medical device (glove), not an algorithm or AI.

    7. Type of Ground Truth Used

    The "ground truth" for these tests are the objective measurement criteria defined by the specified international standards:

    • ASTM D6319-19: Standard Specification for Nitrile Examination Gloves for Medical Application (for dimensions, thickness, physical properties).
    • ASTM D5151-19: Standard Test Method for Detection of Holes in Medical Gloves (for watertight test).
    • ASTM D6124-06 (Reapproved 2017): Standard Test Method for Residual Powder on Medical Gloves.
    • ISO 10993-10: Biological evaluation of medical devices - Part 10: Tests for irritation and skin sensitization (for primary skin irritation and dermal sensitization).
    • ISO 10993-5:2009(E): Biological evaluation of medical devices - Part 5: Tests for in vitro cytotoxicity.
    • ISO 10993-11:2017(E): Biological evaluation of medical devices - Part 11: Tests for systemic toxicity.

    8. Sample Size for the Training Set

    Not applicable. This is not an AI/ML device that requires a training set. The manufacturing process for gloves is subject to quality control and batch testing, which can be seen as ongoing verification of product consistency, but not "training data" in the AI sense.

    9. How the Ground Truth for the Training Set Was Established

    Not applicable, as there is no training set for this type of device.
