The acceptance criteria and performance data provided in the document relate to the physical and chemical properties of the gloves, and their resistance to permeation by chemotherapy drugs and fentanyl.
Here's an analysis of the acceptance criteria and study that proves the device meets them, based on the provided text, focusing on the relevant physical device aspects:

2. Sample Size Used for the Test Set and Data Provenance
- The document does not explicitly state the specific sample sizes used for each physical, chemical, and permeation test. However, tests are typically performed on a statistically relevant number of samples to ensure representativeness and robust results according to the specified ASTM and ISO standards.
- Data Provenance: The tests appear to have been conducted by Encompass Industries Sdn. Bhd. or a contracted lab on their behalf. The company is located in Kertih Bio-Polymer Park, Kemaman, Terengganu, Malaysia. The data is prospective in the sense that the tests were specifically performed on the proposed device for the purpose of this 510(k) submission.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and the Qualifications of Those Experts
- This question is not applicable as the document describes a physical medical device (examination glove) and its material/permeation performance, not a software/AI device that requires expert human interpretation of data for ground truth establishment. The "ground truth" for these tests is based on objective, standardized laboratory measurements (e.g., precise measurements of length, thickness, tensile strength; chemical analysis for powder residue; standardized biological assays for biocompatibility; and analytical chemistry for drug permeation breakthrough times).
4. Adjudication Method for the Test Set
- This question is not applicable for the same reason as point 3. Testing of physical device characteristics and chemical permeation is typically performed according to established laboratory protocols with quantitative, measurable endpoints, not through a process of 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
- This question is not applicable as the document describes a physical medical device (examination glove), not an AI-assisted diagnostic or therapeutic tool.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was done
- This question is not applicable as the document describes a physical medical device (examination glove), not an AI algorithm.
7. The Type of Ground Truth Used
- The "ground truth" for the performance of the examination gloves is based on objective, standardized laboratory measurements and adherence to established international and national standards (e.g., ASTM D6977-19, ASTM D6319-19, ASTM D5151-19, ASTM D412-16, ASTM D573, ASTM D6124-06, ASTM D6978-05, ISO 10993-10, ISO 10993-11, 21 CFR 800.20).
- Examples include:
- Physical measurements: Direct measurement of glove dimensions (length, width, thickness).
- Mechanical properties: Tensile strength and elongation determined by standard material testing methods.
- Integrity: Freedom from holes determined by water leak testing (ASTM D5151-19).
- Chemical analysis: Measurement of residual powder.
- Biocompatibility: In-vivo (skin irritation, sensitization, acute systemic toxicity) tests using animal models, following ISO standards.
- Permeation: Breakthrough detection time of specific chemotherapy drugs and fentanyl using analytical methods (ASTM D6978-05).
- Examples include:
8. The Sample Size for the Training Set
- This question is not applicable as the document describes a physical medical device, which does not involve a "training set" in the context of machine learning or AI.
9. How the Ground Truth for the Training Set Was Established
- This question is not applicable for the same reason as point 8.
§ 880.6250 Non-powdered patient examination glove.
(a)
Identification. A non-powdered patient examination glove is a disposable device intended for medical purposes that is worn on the examiner's hand or finger to prevent contamination between patient and examiner. A non-powdered patient examination glove does not incorporate powder for purposes other than manufacturing. The final finished glove includes only residual powder from manufacturing.(b)
Classification. Class I (general controls). The device, when it is a finger cot, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 880.9.
