Biocompatibility (ISO 10993)(Not directly specified in table, but listed)Non-cytotoxic, Non-sensitizing, Non-irritatingThe document states the device is "Non-cytotoxic, Non-sensitizing, Non-irritating," implying it meets these criteria. Specific test results are not detailed in the provided table but are asserted.

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

  • Fluid Resistance Performance: 32 surgical masks per lot, tested across 3 lots (K-1820-01, J-0720-02, J-0920-03).
  • Particulate Filtration Efficiency: 32 surgical masks per lot, tested across 3 lots (J-0620-01, J-0720-02, J-0920-03).
  • Bacterial Filtration Efficiency: 32 surgical masks per lot, tested across 3 lots (J-0620-01, J-0720-02, J-0920-03).
  • Differential Pressure (Delta-P): 32 surgical masks per lot, tested across 3 lots (J-0620-01, J-0720-02, J-0920-03).
  • Flammability: 32 samples per lot, tested across 3 lots (J-0620-01, J-0720-02, J-0920-03).

The data provenance is non-clinical performance data generated from laboratory testing of the device for various physical and biological properties. The document does not specify the country of origin where the testing was conducted, nor does it classify the data as "retrospective" or "prospective" in the context of clinical studies, as these are non-clinical lab tests.

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

This information is not applicable to this submission. The "ground truth" for the performance criteria of a surgical mask (e.g., filtration efficiency, fluid resistance) is established by industry standards (like ASTM F2100-19, ASTM F1862, ASTM F2299/F2299M-03, ASTM F2101-01, 16 CFR Part 1610, ISO 10993) and regulatory guidance, not by expert consensus on individual cases. The tests are objective measurements performed in laboratories.

4. Adjudication Method for the Test Set

This information is not applicable. Adjudication methods like "2+1" or "3+1" are typically used in clinical studies involving human interpretation (e.g., radiology reads) to resolve discrepancies among experts. For objective laboratory performance tests of a surgical mask, there is no human interpretation or adjudication process in the same sense. The results are quantitative measurements against predefined pass/fail criteria.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and What Was the Effect Size of How Much Human Readers Improve with AI vs Without AI Assistance

No, an MRMC comparative effectiveness study was not done. This type of study is relevant for AI-powered diagnostic or decision support systems where human readers interpret medical images or data. The submitted device is a surgical mask and does not involve AI or human readers for its intended use.

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

No, a standalone algorithm performance study was not done. This concept applies to AI-driven devices. The surgical mask is a physical product, not an algorithm.

7. The Type of Ground Truth Used

The "ground truth" for the performance criteria of the surgical mask is based on established industry standards and regulatory requirements (e.g., ASTM standards, CFR regulations). These standards define the acceptable performance levels for specific physical and biological properties of surgical masks. The test results are objective measurements compared against these predefined numerical criteria.

8. The Sample Size for the Training Set

This information is not applicable. The device is a physical product (surgical mask), not an AI algorithm that requires a training set.

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

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

Examples include surgical caps, hoods, masks, gowns, operating room shoes and shoe covers, and isolation masks and gowns. Surgical suits and dresses, commonly known as scrub suits, are excluded.(b)
Classification. (1) Class II (special controls) for surgical gowns and surgical masks. A surgical N95 respirator or N95 filtering facepiece respirator is not exempt if it is intended to prevent specific diseases or infections, or it is labeled or otherwise represented as filtering surgical smoke or plumes, filtering specific amounts of viruses or bacteria, reducing the amount of and/or killing viruses, bacteria, or fungi, or affecting allergenicity, or it contains coating technologies unrelated to filtration (e.g., to reduce and or kill microorganisms). Surgical N95 respirators and N95 filtering facepiece respirators are exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to § 878.9, and the following conditions for exemption:(i) The user contacting components of the device must be demonstrated to be biocompatible.
(ii) Analysis and nonclinical testing must:
(A) Characterize flammability and be demonstrated to be appropriate for the intended environment of use; and
(B) Demonstrate the ability of the device to resist penetration by fluids, such as blood and body fluids, at a velocity consistent with the intended use of the device.
(iii) NIOSH approved under its regulation.
(2) Class I (general controls) for surgical apparel other than surgical gowns and surgical masks. The class I device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to § 878.9.
