Here's an analysis of the provided information, focusing on acceptance criteria and study details:

1. A table of acceptance criteria and the reported device performance

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

The document does not explicitly state the specific sample sizes used for each individual test conducted on the "Disposable Surgical Isolation Gowns." However, it references various ASTM, ISO, AATCC, and CPSC standards, which would typically define the required sample sizes for each test method. The provenance of the data (country of origin, retrospective/prospective) is not provided. These are non-clinical bench tests performed on the physical product.

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 section is not applicable. The "Disposable Surgical Isolation Gowns" device is a physical product, and its performance is evaluated through standardized laboratory tests (non-clinical tests) against predefined acceptance criteria, not through expert interpretation of data or images. Ground truth here is based on the objective results of these physical and chemical tests.

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

This section is not applicable. As mentioned above, the evaluation involves objective laboratory measurements against set standards, not subjective assessments requiring adjudication by multiple experts.

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

This section is not applicable. The device is a physical medical garment (isolation gown), not an AI-powered diagnostic or assistive technology that would involve human readers or AI assistance.

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

This section is not applicable. The device is a physical medical garment, not an algorithm.

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

The "ground truth" for the performance of the Disposable Surgical Isolation Gowns is based on objective measurements obtained from standardized physical, chemical, and biological tests as defined by national and international standards (e.g., AAMI, ASTM, ISO, CPSC). These standards specify the test methods and the criteria for acceptable performance. For example:

Data Provenance: The document states that the non-clinical tests were conducted to verify that the proposed device met design specifications. Given the applicant's address (Anhui Medpurest Medical Technology Co.,Ltd, China) and the submission correspondent's address (Shanghai SUNGO Management Consulting Co., Ltd, China), it can be inferred that the testing was performed in China or by labs contracted by the applicant. The data is retrospective in nature, as it's a summary of tests already performed for regulatory submission.

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

This document describes non-clinical performance and biocompatibility testing for a physical medical device (surgical gowns). It does not involve diagnostic image analysis or clinical interpretation. Therefore, the concept of "experts establishing ground truth for a test set" in the context of medical image analysis or similar tasks is not applicable here. The ground truth for these tests is established by standardized testing methodologies and instruments as defined by the listed ASTM, AATCC, ISO, and CPSC standards.

4. Adjudication method for the test set

As this is non-clinical performance and material property testing, an adjudication method (like 2+1 or 3+1) is not applicable. The results are quantitative measurements obtained through defined protocols. Pass/Fail criteria are based on exceeding or falling below specified thresholds in the relevant standards.

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, a multi-reader multi-case (MRMC) comparative effectiveness study was not done. This type of study is relevant for AI-powered diagnostic devices where human interpretation is assisted by AI. This submission is for a physical medical device (surgical gowns), and no AI component is described.

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

No, a standalone performance study was not done in the context of an algorithm. This submission is for a physical medical device (surgical gowns) and does not involve an algorithm. The "standalone" performance here refers to the physical and barrier properties of the gown itself, which are measured directly through the non-clinical tests.

7. The type of ground truth used

The ground truth for this device's performance is established by standardized laboratory testing and measurements based on the referenced national and international standards (e.g., AAMI, ANSI, ASTM, AATCC, ISO, CPSC). For example:

• For barrier protection, the ground truth is the measured hydrostatic pressure and water impact performance against the specified level (AAMI Level 3).
• For physical properties like tear strength and breaking strength, the ground truth is the force required to tear or break the material as measured by testing machines.
• For biocompatibility, the ground truth is the measured biological response (e.g., cell viability for cytotoxicity, skin reaction for irritation/sensitization) compared to established toxicity thresholds.

8. The sample size for the training set

Not applicable. This submission is for a physical medical device (surgical gowns) and does not involve AI/machine learning, and therefore does not have a "training set."

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

Not applicable. As there is no training set mentioned or implied for this device, the method for establishing ground truth for a training set is irrelevant.
