The Single Use Surgical Mask is intended to be worn to protect both the patient and healthcare personnel from the transfer of microorganisms, body fluids, and particulate material. This is a single use device provided non-sterile.

The Single-Use Surgical Mask is a 3-ply, disposable surgical face mask. The outer and inner layers of the mask are made of spunbond polypropylene, while the middle layer consists of a meltblown polypropylene filter fabric. The device is secured on the user's face via elastic earloops and are labeled non-sterile, single-use, and disposable. This device is a surface device intended to come in contact with intact skin for a duration of less than 24 hours.

Single-use Surgical Mask Model FE2311B

This document is a 510(k) clearance letter for a Single-Use Surgical Mask and does not contain information about the acceptance criteria or a study proving the device meets criteria in the way typically associated with AI/ML devices or clinical trials.

The document is a regulatory clearance for a physical medical device (a surgical mask), which goes through a different evaluation process than software or AI-driven diagnostics. The "acceptance criteria" for a surgical mask are typically based on material properties and performance standards (e.g., fluid resistance, particulate filtration efficiency, breathability), which are demonstrated through laboratory testing, not clinical studies with "ground truth" established by experts or MRMC studies.

Therefore, I cannot provide the requested information from this document. The questions posed in your prompt (e.g., sample size for test set, number of experts, adjudication methods, MRMC studies, standalone performance, ground truth types and training set details) are relevant for evaluating AI/ML medical devices, but not for a conventional surgical mask as described in this FDA clearance letter.

The provided document is a 510(k) premarket notification for a Single-Use Surgical Mask, not an AI/ML medical device. Therefore, many of the requested criteria regarding AI/ML model acceptance (e.g., sample size for test/training sets, data provenance, expert ground truth, MRMC studies, standalone performance) are not applicable.

The document focuses on demonstrating substantial equivalence to a predicate device primarily through non-clinical performance testing and biocompatibility testing, along with a comparison of physical characteristics.

The document is a 510(k) summary for the BYD Single-use Surgical Mask, মডেল FE2311. It focuses on demonstrating substantial equivalence to a predicate device through non-clinical testing.

Here's the breakdown of the acceptance criteria and the study details:

1. Table of Acceptance Criteria and Reported Device Performance:

The acceptance criteria are established by various standards and the FDA guidance for surgical masks. The reported performance of the subject device (BYD Single-use Surgical Mask) is compared to criteria from these standards and the predicate device.

2. Sample size used for the test set and the data provenance:

• Fluid Resistance: 32 samples were tested.
• Other tests (Particulate Filtration Efficiency, Bacterial Filtration Efficiency, Differential Pressure, Flammability, Biocompatibility): The document does not explicitly state the sample sizes for each of these tests, but it indicates adherence to the respective ASTM and ISO standards, which would define appropriate sample sizes.
• Data Provenance: The tests were non-clinical, conducted in accordance with international standards (ASTM, ISO, CFR) and FDA guidance for surgical masks. No specific country of origin for the test data is mentioned, but the manufacturer is based in China. The data would be considered prospective, as it was generated specifically for this submission.

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 performance study of a device (surgical mask) based on standardized laboratory tests, not a diagnostic or AI-driven system requiring expert ground truth for interpretation of images or patient outcomes. The "ground truth" is established by the test methodologies and results themselves, as defined by the cited standards (e.g., ASTM F2100, ISO 10993). Therefore, the concept of "experts establishing ground truth" in the context of human interpretation is not applicable here. The experts involved would be the laboratory technicians and scientists performing the tests and ensuring compliance with the standards,
and this is not explicitly detailed in the document.

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

Not applicable. This is a non-clinical laboratory performance study, not a study involving human readers or expert adjudication of subjective findings. The test results are objective measurements against defined criteria.

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:

No. This is a 510(k) submission for a physical medical device (surgical mask), not an AI-assisted diagnostic or imaging device. Therefore, MRMC studies and AI assistance are not relevant.

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

No. This is a non-AI medical device. The "standalone performance" refers to the device's intrinsic mechanical and filtration capabilities as measured by the laboratory tests.

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

The "ground truth" is based on standardized test methods and established performance criteria laid out in recognized industry standards (ASTM, ISO, CFR). For example:

• Fluid resistance is "ground-truthed" by passing or failing the 160 mmHg pressure spray.
• Filtration efficiencies are "ground-truthed" by the measured percentage retention of particles or bacteria.
• Biocompatibility is "ground-truthed" by standard cytotoxic, irritation, and sensitization assays.

8. The sample size for the training set:

Not applicable. This is a non-AI medical device; therefore, there is no "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.
