| ISO 10993-10:2010 | Irritation | Not an irritant | Not an irritant |
| Sensitization | Not a sensitizer | Not a sensitizer | |
| ISO 10993-5:2009 | In vitro cytotoxicity | N/A (implied non-cytotoxic) | N/A (implied non-cytotoxic) |

Note: The document explicitly states that "The above data of size, performance, and physical specifications of proposed gloves meet all the current specifications listed in the ASTM standard D6319." and that the bench tests "demonstrated that the proposed device complies with the following standards".
2. Sample size used for the test set and the data provenance
The document does not specify the exact sample sizes for each test that was performed. It generally refers to "bench tests" for physical properties and "biocompatibility tests".
- Provenance: No specific country of origin is mentioned for the test data itself, beyond the manufacturer being in China. The study is non-clinical bench testing, not human data.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
Not applicable. This is a medical glove, and the "ground truth" for its performance is established by adherence to recognized international standards (ASTM, ISO) through objective physical and biocompatibility testing, not expert consensus on interpretations of complex medical images or outcomes.
4. Adjudication method for the test set
Not applicable, as the tests are objective measurements against 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
Not applicable. This is a medical glove, not an AI-powered diagnostic device.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. This is a medical glove, not an algorithm.
7. The type of ground truth used
The ground truth used for performance evaluation is defined by international consensus standards for medical gloves (ASTM D6319-15, ASTM D5151-06, ASTM D6124-17) and biocompatibility testing standards (ISO 10993-10:2010, ISO 10993-5:2009). The device is tested against the specified parameters and thresholds outlined in these standards.
8. The sample size for the training set
Not applicable. This is a physical medical device (gloves), not an AI algorithm requiring a training set.
9. How the ground truth for the training set was established
Not applicable. This is a physical medical device (gloves), not an AI algorithm.
§ 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.
