The provided document is a 510(k) Premarket Notification for a Surgical Mask, not a deep learning AI device. Therefore, the questions related to deep learning AI evaluation (such as sample size for training/test sets, data provenance, number of experts for ground truth, adjudication methods, MRMC studies, standalone performance, and ground truth establishment for training data) are not applicable to this submission.
The document describes the acceptance criteria and the study that proves the device meets those criteria for Surgical Masks, based on non-clinical performance and biocompatibility testing.
Here's the information extracted from the document relevant to the acceptance criteria and device performance:
1. A table of acceptance criteria and the reported device performance
The document provides several tables detailing the performance characteristics and comparisons. The most direct representation of acceptance criteria and results for the proposed device is found in the "Non-Clinical Test Conclusion" section (pages 7-8).
| Test Method | Purpose | Acceptance Criteria | Reported Device Performance (Results) |
|---|---|---|---|
| ASTM F2101-19 (Bacterial Filtration Efficiency, BFE) | Verify the Bacterial Filtration Efficiency (BFE) performance of the subject device. | Level 1: ≥95%;Level 2: ≥98%;Level 3: ≥98%; | WK1701-02A (Level 1): 99.9%WK1701-03A (Level 2): 99.8 - 99.9%WK1701-04A (Level 3): 99.8 - 99.9% |
| EN 14683-2019+AC:2019 Annex C (Differential Pressure) | Verify the Differential Pressure (Delta P) performance of the subject device. | Level 1: < 5.0 H2O/cm2;Level 2: < 6.0 H2O/cm2;Level 3: < 6.0 H2O/cm2; | WK1701-02A (Level 1): Average 2.7 – 3.4 H2O/cm2WK1701-03A (Level 2): Average 2.7 – 3.5 H2O/cm2WK1701-04A (Level 3): Average 2.8 - 3.3 H2O/cm2 |
| ASTM F2299-03 (Particulate Filtration Efficiency, PFE) | Verify the Sub-micron particulate filtration efficiency (PFE) performance of the subject device. | Level 1: ≥95%;Level 2: ≥98%;Level 3: ≥98%; | WK1701-02A (Level 1): 99.45 - 99.97%WK1701-03A (Level 2): 99.41 - 99.98%WK1701-04A (Level 3): 99.58 - 99.77% |
| ASTM F1862-17 (Resistance to Synthetic Blood Penetration) | Verify the Resistance to Penetration by Synthetic Blood performance of the subject device. | Level 1: 80 mmHg;Level 2: 120 mmHg;Level 3: 160 mmHg; | WK1701-02A (Level 1): None Seen under 80 mmHgWK1701-03A (Level 2): None Seen under 120 mmHgWK1701-04A (Level 3): None Seen under 160 mmHg |
| 16 CFR 1610 (Flammability) | Verify the Flame spread performance of the subject device. | Class 1 | Class 1 (Ignited, but extinguished) |
| ISO 10993-5: 2009 (Cytotoxicity) | Verify the Cytotoxicity potential of the subject device. | Non-cytotoxic | Under the conditions of this study, the test article have no potential toxicity to L-929 cells. |
| ISO 10993-10: 2010 (Irritation and Sensitization) | Verify the Irritation and Sensitization potential of the subject device. | Non-irritating and Non-sensitizing | The test article showed no evidence of causing delayed dermal contact sensitization in the guinea pig.The test result showed that the response of the test article extract was categorized as negligible under the test condition. |
2. Sample size used for the test set and the data provenance
- Sample Size: Non-clinical tests were conducted using "3 nonconsecutive lots with 32 samples per lot" for verification. This suggests a total of 96 samples (3 lots * 32 samples/lot) were tested for performance characteristics across all models.
- Data Provenance: The manufacturer is Jiangmen Ningrui Medical Supplies Co., Ltd. in China. The tests are non-clinical (laboratory performance and biocompatibility tests), not clinical data from patients. The document does not specify if the testing was performed retrospectively or prospectively, but typically lab verification tests are conducted prospectively during development and manufacturing.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
N/A. This document pertains to non-clinical performance and biocompatibility testing of a physical medical device (surgical mask), not an AI/deep learning system requiring expert consensus for ground truth on clinical images. The "ground truth" for these tests is established by standardized laboratory methods and measurements (e.g., flow rates, particle counts, chemical reactions, physical observations).
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
N/A. Adjudication methods are relevant for subjective interpretations, common in clinical imaging for AI device evaluation. This is a physical device tested against objective, quantitative 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
N/A. This is not an AI device. No human reader studies or MRMC comparative effectiveness studies were performed. The comparative effectiveness is against the stated ASTM and ISO standards and a predicate device's performance, not human performance with/without AI assistance.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
N/A. This is not an AI algorithm. The performance tests are "standalone" in the sense that they evaluate the mask itself against specified physical and biological criteria, without human interaction during the test other than operating the testing equipment.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
The "ground truth" for the performance characteristics of surgical masks is established by the standardized test methods themselves (e.g., ASTM F2100, ASTM F1862, EN 14683, ISO 10993, 16 CFR 1610). These standards define the acceptable range or threshold for a given physical or biological property (e.g., a specific BFE percentage, a maximum differential pressure, absence of cytotoxicity). The results are quantitative measurements against these predefined, objective criteria.
8. The sample size for the training set
N/A. This is not an AI/machine learning device; there is no "training set."
9. How the ground truth for the training set was established
N/A. There is no training set for this type of device submission.

§ 878.4040 Surgical apparel.
(a)
Identification. Surgical apparel are devices that are intended to be worn by operating room personnel during surgical procedures to protect both the surgical patient and the operating room personnel from transfer of microorganisms, body fluids, and particulate material. 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.
