AI/ML Overview

The provided text describes the acceptance criteria and the study conducted for a Disposable Medical Face Mask (DF3-001) to verify its performance and safety.

1. Table of acceptance criteria and the reported device performance:

ItemPurposeAcceptance CriteriaReported Device PerformanceResult
Fluid Resistance ASTM F1862Assess the performance of a mask to resistance to a synthetic blood preparation targeted toward the mask at a set pressure29 out of 32 pass at 160 mmHg for level 3Lot1, Lot2, Lot3: 32 out of 32 pass at 160 mmHg (tested over 3 non-consecutive lots, using a sample size of 32 masks/lot)PASS
Particulate Filtration Efficiency ASTM F2299Assess the performance of a mask to penetration by sub-micron polystyrene latex particles of 0.1 micron≥ 98%Lot1: 99.35% Lot2: 99.46% Lot3: 98.69% (tested over 3 non-consecutive lots, using a sample size of 32 masks/lot)PASS
Bacterial Filtration Efficiency ASTM F2101Assess the performance of a mask to penetration by a prepared solution with known concentration of an indicator bacterial organism≥ 98%Lot1: 99.88% Lot2: 99.87% Lot3: 99.88% (tested over 3 non-consecutive lots, using a sample size of 32 masks/lot)PASS
Differential Pressure (Delta P) EN 14683 Annex CAssess the performance of a mask for resistance to air movement through the materials of the face of the mask< 6.0 mmH2O/cm²Lot1: 4.13 mmH2O/cm² Lot2: 4.18 mmH2O/cm² Lot3: 4.24 mmH2O/cm² (tested over 3 non-consecutive lots, using a sample size of 32 masks/lot)PASS
Flammability 16 CFR 1610Assess the resistance of a mask to ignitionClass ILot1, Lot2, Lot3: Class I (tested over 3 non-consecutive lots, using a sample size of 32 masks/lot)PASS
CytotoxicityAssess the potential risk of Cytotoxicity of mask materialNon-CytotoxicPASS: Under the conditions of the study, the device is non-cytotoxic.PASS
IrritationAssess the potential risk of Irritation of mask materialNon-IrritatingPASS: Under the conditions of the study, the device is non-irritating.PASS
SensitizationAssess the potential risk of Sensitization of mask materialNon-SensitizingPASS: Under the conditions of the study, the device is non-sensitizing.PASS

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

For all performance tests (Fluid Resistance, Particulate Filtration Efficiency, Bacterial Filtration Efficiency, Differential Pressure, and Flammability), the sample size used was 32 units per lot, across 3 non-consecutive lots.

The data provenance is not explicitly stated in terms of country of origin or whether it was retrospective or prospective. However, the document is a 510(k) submission to the US FDA from a Chinese applicant (Wellmed Dental Medical Supply Co., Ltd. in Shenzhen, China), suggesting the tests were likely conducted by or for the manufacturer in China or by a certified lab for regulatory submission purposes. These are non-clinical (laboratory) tests performed specifically for regulatory approval.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

This is a non-clinical, laboratory-based performance and biocompatibility study for a medical device (face mask). There is no "ground truth" in the clinical sense established by human experts like radiologists. The "ground truth" is determined by established scientific standards and test methods (e.g., ASTM, EN, ISO standards), with results measured by laboratory equipment and qualified personnel following those protocols. Therefore, the concept of "number of experts" and their "qualifications" for establishing ground truth as typically understood in AI/clinical studies does not apply here.

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

Not applicable. This is a non-clinical, laboratory-based performance and biocompatibility study. Adjudication methods are typically relevant for human-interpreted data, such as medical images or clinical diagnoses.

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 a non-clinical study for a medical face mask. It does not involve human readers, AI, or clinical effectiveness studies in this context.

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

Not applicable. This device is a physical medical product (a face mask), not a software algorithm.

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

The "ground truth" in this context is defined by the objective, reproducible measurements against established performance standards and specifications outlined in the referenced international standards (e.g., ASTM F1862, ASTM F2299, ASTM F2101, EN 14683, 16 CFR 1610, ISO 10993). The acceptance criteria for each test (e.g., "$\geq$ 98%," "< 6.0mmH2O/cm²") numerically define the acceptable performance.

8. The sample size for the training set:

Not applicable. This is a physical medical device, not an AI/machine learning model that requires a training set.

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

Not applicable, as there is no training set for this type of 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.
