The surgical masks are intended to be worn to protect both the patient and healthcare personnel from transfer of microorganisms, body fluids, and particulate material. These masks are intended for use in infection control practices to reduce the potential exposure to bloody fluids. This is a single-use, disposable device, provided non-sterile.
XX0009 Ear loop Level: Level 1, Level 2 and Level 3
XX0008 Tie-on Level: Level 1, Level 2 and Level 3
XX0006 Tie-on with shield Level: Level 1, Level 2 and Level 3
XX0005 Ear loop with shield Level: Level 1, Level 2 and Level 3
The surgical masks are single use, flat-pleated masks that are provided in blue. The outer and inner layers of the mask are made of spunbond polypropylene. The middle filter is made of one layer of meltblown polypropylene filter. The Surgical Masks are available in four types due to different configurations, including ear loop, tie-on, ear loop with shield and tie-on with shield. Detail configurations of them are presented in Table 1 Surgical Masks Description. The ties are made of spunbond polypropylene and the ear loops are made of spandex. The shield is made of PET. The nose piece is made of iron wire and polypropylene. Users can adjust the nose piece according to the shape of the bridge of the nose, and fix the mask on the bridge of the nose to prevent the mask from falling off. The proposed devices are provided in non-sterile. The proposed devices contain four (4) types of masks: XX0009, XX008, XX0006 and XX0005. Each of these types have three different levels, level 2, and level 3. Therefore, the proposed devices have 12 models in toto, and detailed model information is provided in Table 1.
The provided text is a 510(k) Summary for Surgical Masks (K212120), focusing on demonstrating substantial equivalence to a predicate device (K160269) through non-clinical testing. It does not describe a study involving an AI (Artificial Intelligence) or medical imaging device, nor does it involve a multi-reader multi-case (MRMC) study. Therefore, many of the requested details, such as human reader improvement with AI assistance, ground truth establishment for AI training/test sets, or the number of experts for adjudication, are not applicable to this document.
However, I can extract the relevant information regarding the acceptance criteria and the study that proves the device meets those criteria, specifically for the surgical masks.
Acceptance Criteria and Device Performance for Surgical Masks (Based on Non-Clinical Tests)
1. Table of Acceptance Criteria and Reported Device Performance
The non-clinical tests were conducted to verify that the proposed device met all design specifications. The performance levels (Level 1, Level 2, Level 3) refer to classifications defined by ASTM F2100: 2019 "Standard Specification for Performance of Materials Used in Medical Face Masks."
| Test Methodology | Purpose | Acceptance Criteria | Reported Device Performance |
|---|---|---|---|
| Particulate Filtration Efficiency (PFE) | Determines the particle filtration efficiency (PFE) of the test article (ASTM F2299/F2299M-03 (2017)) | Level 1: ≥95%Level 2: ≥98%Level 3: ≥98% | Level 1: Pass at 96.17%Level 2: Pass at 98.95%Level 3: Pass at 99.06% |
| Bacterial Filtration Efficiency (BFE) | Determines the bacterial filtration efficiency (BFE) of the test article using a biological aerosol of Staphylococcus aureus (ASTM F2101: 2019) | Level 1: ≥95%Level 2: ≥98%Level 3: ≥98% | Level 1: Pass at 96.80%Level 2: Pass at 98.90%Level 3: Pass at 99.04% |
| Differential Pressure | Measures the breathability of the mask (EN 14683:2019+AC: 2019 Annex C) | Level 1: <5.0 mmH₂O/cm²Level 2: <6.0 mmH₂O/cm²Level 3: <6.0 mmH₂O/cm² | Level 1: Pass at 4.0 mmH₂O/cm²Level 2: Pass at 5.1 mmH₂O/cm²Level 3: Pass at 5.2 mmH₂O/cm² |

| Irritation | Evaluates the irritation potential of the test sample (ISO 10993-10:2010) | Non-irritating | Under the conditions of the study, the proposed device was non-irritating. |
2. Sample Size Used for the Test Set and Data Provenance
The document does not explicitly state the specific sample size (number of masks or material samples) used for each non-clinical test. These tests are typically conducted on a statistically significant number of samples per batch or according to the specific standard's requirements, but the exact count is not detailed in this summary.
The provenance of the data is that these are non-clinical laboratory test results performed to demonstrate compliance with recognized consensus standards (ASTM, ISO, EN, CFR). The tests were performed for a Chinese manufacturer (Hubei Xinxin Non-woven Co., Ltd.) for submission to the U.S. FDA. The data is implicitly prospective testing conducted specifically for this regulatory submission.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications of Experts
Not applicable. These are physical and biological performance tests on a device (surgical masks), not image-based diagnostic tests or AI performance evaluations requiring expert radiologists or similar medical professionals for ground truth establishment. The "ground truth" for these tests is defined by the objective measurement results according to the specified standard methods.
4. Adjudication Method for the Test Set
Not applicable. This is not a study that requires human adjudication of subjective data. The results are based on objective, standardized laboratory measurements.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done
No, an MRMC comparative effectiveness study was not done. This submission is for surgical masks, not an AI or imaging device that would typically involve a human-in-the-loop diagnostic task.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was done
Not applicable. This is a physical medical device (surgical mask), not a software algorithm.
7. The Type of Ground Truth Used
The "ground truth" for the performance of the surgical masks is established by objective, standardized laboratory measurements performed according to internationally recognized consensus standards (e.g., ASTM, ISO, EN). For biocompatibility, it's the biological response observed based on in-vitro (cytotoxicity) and in-vivo (irritation, sensitization) assays against defined criteria.
8. The Sample Size for the Training Set
Not applicable. This device is not an AI model, and therefore, it does not have a "training set" in the context of machine learning.
9. How the Ground Truth for the Training Set Was Established
Not applicable, as there is no training set for this device.

§ 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.
