Biocompatibility Test Results:
| Test Method | Purpose | Acceptance Criteria | Reported Device Performance (Results) |
|---|---|---|---|
| ISO 10993-5:2009 In Vitro Cytotoxicity | To test the potential cytotoxicity of the test article on mammalian L-929 cells. Cells were exposed to extracts of the mask, and morphology, cell lysis, and cytotoxicity were observed and determined by MTT assay. | The 50% extract of the test article should have at least the same or a higher viability than the 100% extract. Otherwise, the test should be repeated. If viability is reduced to <70% of the blank, it has a cytotoxic potential. The Viab.% of the 100% extract of the test article is the final result. | Under the condition of the test, the test article was found to be cytotoxic. |
| Skin Sensitization ISO 10993-10:2010 | To observe skin sensitization in guinea pigs after intradermal and topical induction with extracts of the test article. Challenge phase observed for erythema and edema, and scored according to Magnusson and Kligman scales. | Magnusson and Kligman grades of 1 or greater in the test group generally indicate sensitization, provided grades of less than 1 are seen in control animals. If grades of 1 or greater are noted in control animals, then the reactions of test animals which exceed the most severe reaction in control animals are presumed to be due to sensitization. If the response is equivocal, rechallenge is recommended to confirm the results from the first challenge. The outcome of the test is presented as the frequency of positive challenge results in test and control animals. | Under the conditions of the test, the test article was found to be non-sensitizing. |
| Skin Irritation test ISO 10993-10:2010 | To observe skin irritation in New Zealand white Rabbits after exposure to extracts of the test article. Extracts were applied to skin, bandages were removed after 4 hours, and skin reactions (erythema and edema) were scored at 1h, 24h, 48h, and 72h. The primary irritation score was calculated. | Use only (24±2) h, (48±2) h and (72±2) h observations for calculation. The primary irritation score for an animal was calculated by dividing the sum of all the scores by 6. To obtain the primary irritation index for the test article, add all the primary irritation scores of the individual animals and divide by the number of animals. Subtract control scores if applicable. | Under the conditions of the test, the test article was found to be non-irritating. |
| Acute systemic toxicity ISO 10993-11:2017 | To evaluate acute systemic toxicity in mice through intraperitoneal injection of a single dose of the test article extract. Mice were observed for adverse clinical reactions, systemic reactions, and weighed daily for three days. Gross necropsy for animals found dead or showing abnormal signs. | (1) If none of the mice treated with the test article extract exhibited a significantly greater biological reactivity than control mice, the test article met the requirements. If two or more animals died, or abnormal behavior occurs in two or more animals, or body weight loss >10% occurs in three or more animals, the test article did not meet the requirements. (2) If slight signs are observed, and no more than one animal showed gross symptoms or died, repeat with ten animals. If all ten animals show no meaningful biological reactivity, the test article met the requirements. | Under the condition of the test, the test article was found to be non-systemic toxicity. |

Study Details (Applicable to a Medical Device Performance Test)
2. Sample size used for the test set and the data provenance:
- Sample Size:
- For Fluid Resistance Performance (ASTM F1862): 32 samples were tested.
- Data Provenance: The tests were conducted according to established ASTM and MIL-M standards. The country of origin of the data is not explicitly stated beyond the manufacturer's location in China. The data is retrospective in the sense that it's a test of the manufactured product to demonstrate compliance.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- This is not applicable as this is a performance test for a physical device, not an AI algorithm requiring expert ground truth for image interpretation or diagnosis. The "ground truth" is defined by the objective measurement protocols of the ASTM and MIL standards.
4. Adjudication method for the test set:
- Not applicable for a physical device performance test. Test results are quantitative measurements against predefined thresholds.
5. If a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was done:
- No, an MRMC study was not done. This type of study is relevant for diagnostic devices that involve human interpretation (e.g., radiology AI). This submission is for a surgical mask.
6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done:
- Not applicable. This is not an AI algorithm. The performance tests (e.g., filtration efficiency, fluid resistance) are "standalone" in the sense that they are objective measurements of the mask's physical properties.
7. The type of ground truth used:
- The ground truth is based on objective measurement standards and specifications (e.g., ASTM F2100, ASTM F1862, ASTM F2299, ASTM F2101, MIL-M36954C, 16 CFR 1610, ISO 10993-1). For example, for "Fluid Resistance," the ground truth is the pressure at which fluid penetrates the mask when challenged with a synthetic blood spray.
8. The sample size for the training set:
- Not applicable. This is a physical device, not an AI model that requires a training set. The manufacturing process itself could be seen as "training" in a very abstract sense, but not in the context of machine learning.
9. How the ground truth for the training set was established:
- Not applicable. As above, this is not an AI model with a training set and associated ground truth.

Study Details (for a physical product, not an AI/ML algorithm)
It's important to reiterate that this is a submission for a physical medical device (surgical mask), not an AI/ML algorithm. Therefore, many standard AI/ML study components do not apply.
-
Sample size used for the test set and the data provenance:
- Test Set: No explicit "test set" in the AI/ML sense is mentioned. Instead, samples of the manufactured masks were subjected to various standardized non-clinical tests. The document does not specify the number of masks or samples tested for each criterion (e.g., how many masks were tested for BFE, how many for fluid resistance).
- Data Provenance: The tests were conducted by the manufacturer/sponsor (Tianjin Teda Jinshan Easy Packing Manufacture Co., Ltd., China) as part of their verification process for the 510(k) submission. This would be considered "prospective" in the sense that the tests were performed specifically for this submission, on samples of the device.
-
Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- Not Applicable. Ground truth in the context of a physical device like a surgical mask is established by validated laboratory testing methods and compliance with published standards (e.g., ASTM, ISO). There are no human "experts" establishing a subjective "ground truth" for each mask. The "ground truth" is the quantitative result from the standardized test.
-
Adjudication method (e.g. 2+1, 3+1, none) for the test set:
- None. Adjudication methods are relevant for subjective interpretations, typically in image analysis or clinical assessments. For standardized physical material testing, the results are quantitative and objective measurements from the validated test methods.
-
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 physical device, not an AI-assisted diagnostic tool.
-
If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
- Not Applicable. This is a physical device, not an AI algorithm. Its performance is inherent to its materials and construction.
-
The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
- Objective Laboratory Test Results against Established Standards: The "ground truth" for the performance of the Disposable Medical Surgical Masks is the objective measurement obtained through specific, validated laboratory test methods (e.g., ASTM F2101 for BFE, ASTM F1862 for fluid resistance) and comparison against the specified acceptance criteria within those standards (e.g., ASTM F2100 Level 3 requirements).
-
The sample size for the training set:
- Not Applicable. This is a manufactured physical device, not an AI/ML model that requires a training set. The manufacturing process is analogous to a "training" phase where the design and materials are refined to meet specifications.
-
How the ground truth for the training set was established:
- Not Applicable. As above, no training set for an AI algorithm. The manufacturing process of a physical device involves quality control and adherence to specifications to ensure the final product meets its intended performance, which is then verified through non-clinical testing.

| Sensitization | Non-sensitizing | Under the conditions of the study, the subject device non-polar and polar extracts were determined to be non-sensitizing. | Pass |
2. Sample size used for the test set and the data provenance:
- Sample Size:
- For Fluid Resistance (ASTM F1862): 32 samples were tested, with 29 passing the 160 mmHg threshold.
- For other performance tests (Particulate Filtration Efficiency, Bacterial Filtration Efficiency, Differential Pressure, Flammability): The specific sample size per test is not explicitly stated but is implied to be sufficient to meet the standards (e.g., "Pass" results).
- For Biocompatibility testing: The sample size for each test (Cytotoxicity, Irritation, Sensitization) is not explicitly stated.
- Data Provenance: The document does not specify the country of origin of the data or whether the studies were retrospective or prospective, beyond stating that non-clinical tests were conducted. Given the nature of performance and biocompatibility testing for a physical medical product, these are almost certainly prospective laboratory tests following standardized protocols.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- Not Applicable. This is a physical medical device. "Ground truth" in the context of AI/ML evaluation (e.g., expert consensus on medical images) does not apply here. The "ground truth" for this device is established by the results of standardized laboratory tests conducted according to established protocols (e.g., ASTM, ISO standards).
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:
- Not Applicable. As this is a performance evaluation of a physical device against predefined quantitative standards, an adjudication method for human interpretation is not relevant. The results are objective measurements from laboratory equipment.
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 device is a surgical mask, not an AI-driven diagnostic or assistive tool. Therefore, MRMC studies are not relevant.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
- Not Applicable. This is a physical device, not a software algorithm.
7. The type of ground truth used (expert concensus, pathology, outcomes data, etc):
- Standardized Test Results / Quantitative Measurements: The "ground truth" is based on the objective outcomes of laboratory tests performed according to recognized industry standards (e.g., ASTM F2101 for Bacterial Filtration Efficiency, ASTM F1862 for Fluid Resistance). These standards define the methodology and the acceptable performance thresholds.
8. The sample size for the training set:
- Not Applicable. This is a physical medical device, not an AI/ML model that requires a training set.
9. How the ground truth for the training set was established:
- Not Applicable. As there is no AI/ML model or training set, the concept of establishing ground truth for a training set does not apply.
