The ties welded are used to keep the mouth and the nose. The tie is made of spunbond polypropylene. The nose wire is to allow the user to fit the facemask around their nose, which is made of polyethylene wire. The surgical masks will be provided in Blue. The procedure masks are sold non-sterile and are intended to be single use, disposable device.
The provided document is a 510(k) Premarket Notification for a Procedure Mask/Surgical Mask. It describes the device's technical specifications and performance testing. However, it is important to note that this document is for a medical device (a mask) and not a software or AI-based device. Therefore, many of the requested elements for describing an AI study, such as sample size for test sets, data provenance, number of experts for ground truth, adjudication methods, MRMC studies, or training set details, are not applicable in this context.
The document focuses on demonstrating that the proposed device is substantially equivalent to a legally marketed predicate device by meeting certain performance criteria.
Here's the information derived from the document that is applicable to your request, formatted as closely as possible:
1. Table of Acceptance Criteria and Reported Device Performance
The device was tested against the ASTM F2100 requirements for Level 1 and Level 3 masks.
Acceptance Criteria and Device Performance for Level 1 Masks:
| Item | Acceptance Criteria (Level 1) | Proposed Device (Model 68-8506-G) Performance | Proposed Device (Model 68-8536-B) Performance | Result |
|---|---|---|---|---|
| Fluid Resistance | $\ge$ 29 out of 32 pass at 80 mmHg | 32 out of 32 passed at 80 mmHg, 3 lots | 32 out of 32 passed at 80 mmHg, 3 lots | PASS |
| Particulate Filtration Efficiency | $\ge$ 95% | 97.4%, 97.5%, 97.5% | 97.2%, 97.1%, 97.1% | PASS |
| Bacterial Filtration Efficiency | $\ge$ 95% | 99.9% 3 lots | 99.9% 3 lots | PASS |
| Differential Pressure | < 5.0 mmH₂O/cm² | 2.9, 2.8, 2.7 mmH₂O/cm² | 3.7, 3.4, 3.7 mmH₂O/cm² | PASS |
| Flammability | Class 1 | Class 1 | Class 1 | PASS |
Acceptance Criteria and Device Performance for Level 3 Masks:
| Item | Acceptance Criteria (Level 3) | Proposed Device (Model 68-8508-G) Performance | Proposed Device (Model 68-8538-B) Performance | Result |
|---|---|---|---|---|
| Fluid Resistance | $\ge$ 29 out of 32 pass at 160 mmHg | 32 out of 32 passed at 160 mmHg, 3 lots | 32 out of 32 passed at 160 mmHg, 3 lots | PASS |
| Particulate Filtration Efficiency | $\ge$ 98% | 98.2%, 98.4%, 98.4% | 98.4%, 98.4%, 98.3% | PASS |
| Bacterial Filtration Efficiency | $\ge$ 98% | 99.9%, 3 lots | 99.9%, 3 lots | PASS |
| Differential Pressure | < 6.0 mmH₂O/cm² | 3.4, 3.0, 3.0 mmH₂O/cm² | 4.1, 3.4, 3.4 mmH₂O/cm² | PASS |
| Flammability | Class 1 | Class 1 | Class 1 | PASS |
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 Test Set:
- Fluid Resistance (ASTM F1862): 32 samples per lot, across 3 lots for both Level 1 and Level 3 masks. (e.g., "32 out of 32 passed at 80 mmHg, 3 lots")
- Particulate Filtration Efficiency (ASTM F2299): Not explicitly stated how many individual samples were tested, but results are reported as percentages for "3 lots."
- Bacterial Filtration Efficiency (ASTM F2101): Not explicitly stated how many individual samples were tested, but results are reported as percentages for "3 lots."
- Differential Pressure (EN 14683): Not explicitly stated how many individual samples were tested per lot, but results are reported with three values for each model (e.g., "2.9, 2.8, 2.7 mmH₂O/cm²"), likely representing different samples or averages across lots.
- Flammability (16 CFR 1610): Not explicitly stated.
- Data Provenance: The document implies that the tests were conducted by the manufacturer or a third-party lab on samples of their manufactured masks. The manufacturer is KENPAX INTERNATIONAL LIMITED, located in Hong Kong, China. The testing therefore likely occurred in China or at a contract lab. The data is prospective in the sense that these tests were performed on new device samples to demonstrate compliance.
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)
This type of information is not applicable. The "ground truth" for medical masks is established by validated standardized test methods (e.g., ASTM standards) and not by expert clinical consensus. The performance is measured objectively using specified laboratory procedures.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Not applicable, as this is objective performance testing against a standard, not classification based on expert opinions.
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 for a physical medical device (mask), not an AI system.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. This is for a physical medical device (mask), not an AI system. The tests are for the physical properties of the mask.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
The "ground truth" is based on established engineering and materials science standards for mask performance (e.g., flow rates, particle sizes, microbial viability, fluid pressure) as defined by organizations like ASTM and EN. For example, the ground truth for Bacterial Filtration Efficiency (BFE) is derived from the established protocol of the ASTM F2101 standard, which dictates the aerosolization of Staphylococcus aureus and measurement of filtration effectiveness.
8. The sample size for the training set
Not applicable. This is a physical device, not an AI model that requires a training set.
9. How the ground truth for the training set was established
Not applicable. As above, no AI model or training set is involved.

§ 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.
