The maximum seal strength should be no less than 2.0N/15mm. There should be no dye penetration on the package.PassPass (implied, as results are for "the device")

2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

  • Sample Size for performance tests: For Fluid Resistance, Bacterial Filtration Efficiency, Particulate Filtration Efficiency, Differential Pressure, and Flammability, the sample size was "three lots, 32 per lot" for a total of 96 samples per test.
  • Data Provenance: The tests were conducted by the submitting company, Guangdong Zhizhen Biological Medical Co., Ltd, which is based in China. The document does not specify if the data is retrospective or prospective, but based on the nature of device testing for 510(k) clearance, it is typically prospective for the purpose of demonstrating performance.

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)

  • The document describes non-clinical laboratory testing (e.g., physical properties, filtration efficiency, biocompatibility). It does not involve "experts" establishing ground truth in the sense of medical diagnosis or interpretation of images. The "ground truth" is established by adherence to standardized test methods (e.g., ASTM, ISO, EN standards) and their predefined acceptance criteria. Thus, the expertise lies in the accredited laboratories and personnel performing these specific, standardized tests.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

  • This is not applicable as the study involves standardized laboratory testing against specific criteria, not human interpretation or adjudication of cases.

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

  • No, a multi-reader multi-case (MRMC) comparative effectiveness study was not done. This type of study is typically relevant for AI/imaging devices, not for a surgical mask.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

  • This is not applicable. The device is a physical surgical mask, not an algorithm. The performance tests are for the physical properties of the mask (e.g., filtration, fluid resistance).

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

  • The "ground truth" for these tests is defined by established international standards and regulations (e.g., ASTM F2100-19, ISO 10993 series, EN 14683, 16 CFR 1610, USP <85>). The performance of the device is measured against the quantitative and qualitative acceptance criteria specified in these standards.

8. The sample size for the training set

  • This is not applicable. The submission describes non-clinical testing of a physical device, not an algorithm that requires a training set.

9. How the ground truth for the training set was established

  • This is not applicable, as there is no training set for a physical device like a surgical mask.
