Pro Guard ® 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.
Black Nitrile Examination Gloves Powder Free are Class I patient examination gloves bearing the product code Nitrile - LZA (21 CFR 880.6250). The gloves are made from acrylonitrile-butadiene copolymer dispersion. These gloves are black in color and are powder free.
The provided document is a 510(k) summary for a medical device: "Pro Guard® Nitrile Powder Free Examination Glove." This type of document is a submission to the FDA to demonstrate substantial equivalence to a legally marketed predicate device, not typically a study proving the efficacy or performance of a new medical AI device.
Therefore, the requested information regarding acceptance criteria and study design for an AI device (e.g., sample size for test/training sets, expert ground truth, MRMC studies, standalone performance) is not applicable to this document.
The document discusses the performance of a physical medical device (gloves) against established standards for physical properties and biocompatibility.
Here's the relevant information extracted from the provided text, structured to best fit the spirit of your request, but acknowledging the difference in device type:
Device: Pro Guard® Nitrile Powder Free Examination Glove
Device Type: Class I, reserved Non-powdered patient examination glove

*The "Reported Device Performance" column directly reflects the "Result" column from the provided 510(k) summary (page 7).
The following points are not applicable to this 510(k) submission for a physical medical glove. They typically pertain to AI/machine learning medical devices.
- 2. Sample sizes for test set and data provenance: Non-clinical physical tests are described, not AI model testing. The sample sizes for each test are listed next to the "Acceptance Criteria," e.g., 200 pieces for watertight test, 5 pieces for residual powder. The data provenance is implied to be from the manufacturer's own testing in Thailand.
- 3. Number of experts used to establish ground truth & qualifications: Ground truth for physical properties is established by objective measurements against international standards (ASTM, ISO), not by expert consensus in the way an AI medical imaging task would require.
- 4. Adjudication method: Not applicable as it's not an AI performance study requiring human interpretation.
- 5. Multi-reader multi-case (MRMC) comparative effectiveness study: Not applicable. This is for evaluating changes in human reader performance with AI assistance.
- 6. Standalone (algorithm only without human-in-the-loop performance) study: Not applicable. This is a physical device, not an algorithm.
- 7. Type of ground truth used: For physical properties, the ground truth is objective measurement against specified standards (e.g., length in mm, thickness in mm, tensile strength in MPa, number of holes). For biocompatibility, it's based on standardized biological tests.
- 8. Sample size for the training set: Not applicable. This is not an AI/ML device that requires training data.
- 9. How the ground truth for the training set was established: Not applicable.
