1. Table of Acceptance Criteria and Reported Device Performance

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

• Physical and Dimensions Testing: Inspection Level S-2, AQL 4.0. The specific number of gloves tested is not provided, but these AQL levels dictate the sampling plan. Data provenance is not explicitly stated beyond being conducted by the manufacturer, Shijiazhuang Dilly Plastics Products Co., Ltd.
• FDA 1000 ml. Water Fill Test: Inspection Level S-4, AQL 2.5. The specific number of gloves tested is not provided, but these AQL levels dictate the sampling plan. Data provenance is not explicitly stated beyond being conducted by the manufacturer.
• Primary Skin Irritation and Skin Sensitization: The document does not specify the sample size (e.g., number of subjects, number of tests) for these biocompatibility tests, nor does it explicitly state the country of origin or whether the studies were retrospective or prospective.

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

• Not Applicable. This document pertains to the 510(k) submission for patient examination gloves, which does not involve subjective diagnostic interpretations requiring expert consensus for ground truth establishment. The "ground truth" for these tests (e.g., pinhole presence, skin irritation) is based on objective measurements and established protocols.

4. Adjudication method for the test set:

• Not Applicable. As the device is examination gloves and the tests are objective physical and chemical assessments, there is no need for an adjudication method in the context of expert review or consensus, such as 2+1 or 3+1.

5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done:

• No. An MRMC comparative effectiveness study is not applicable for this type of device (patient examination gloves). These studies are typically used for diagnostic imaging devices where human readers interpret medical images, and the AI's impact on their performance is evaluated.

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

• Not Applicable. This device is patient examination gloves, not an algorithm or AI system. Therefore, a standalone performance evaluation of an algorithm is not relevant.

7. The type of ground truth used:

• The "ground truth" for the tests performed is based on:
  • Objective measurements against established standards: For physical and dimensional properties, the ground truth is whether the glove meets the specifications of ASTM-D-5250-92.
  • Objective experimental outcomes: For the pinhole test, the ground truth is whether water penetrates the glove under specified conditions. For biocompatibility, the ground truth is the presence or absence of a measurable irritating or sensitizing reaction.

8. The sample size for the training set:

• Not Applicable. This documentation is for a physical medical device (examination gloves), not an AI/ML algorithm that requires a training set. The tests performed are quality control and performance verification tests for manufactured products.

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

• Not Applicable. As there is no AI/ML algorithm or training set involved, the concept of establishing ground truth for a training set does not apply.

Here's an analysis of the provided text regarding the acceptance criteria and the study proving the device meets them, structured as requested:

Device: Shijiazhuang Dilly Plastics Products Co., Ltd. Synthetic Powder-Free Vinyl Patient Examination Gloves

Acceptance Criteria and Device Performance:

Study Details:

• Sample size used for the test set and the data provenance:

  • ASTM D5250-92 Physical and Dimensions Testing: "Inspection Level S-2, AQL 4.0." (Specific sample size not explicitly stated, but determined by the AQL level for lots.)
  • FDA 1000 ml. Water Fill Test: "AQL 2.5, Inspection Level S-4." (Specific sample size not explicitly stated, but determined by the AQL level for lots.)
  • Primary Skin Irritation and Skin Sensitization Testing: Not explicitly stated.
  • USP Iodine Test for Starch: Not explicitly stated.
  • Data Provenance: The document implies in-house testing conducted by Shijiazhuang Dilly Plastics Products Co., Ltd. in P.R. China, presumably on newly manufactured gloves. This would be considered prospective for the specific batches tested.

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

  • The document describes performance against established industry standards (ASTM D5250-92) and FDA test methods (1000 ml. Water Fill Test, USP Iodine Test), as well as biocompatibility testing. It does not mention expert consensus for establishing ground truth in the context of diagnostic interpretation. Ground truth for these criteria is defined by the objective pass/fail parameters outlined in the respective standards and test methodologies.

• Adjudication method for the test set:

  • No adjudication method (like 2+1, 3+1) is mentioned as this is not a study involving subjective interpretations (e.g., image reading). The tests are objective measurements against defined criteria in standards.

• 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 device is a physical examination glove, not an AI-powered diagnostic or assistive tool for human readers.

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

  • No. This device is a physical product and does not involve an algorithm.

• The type of ground truth used:

  • The ground truth for the performance criteria is based on objective, standardized measurements and pass/fail criteria defined by ASTM D5250-92, FDA test methods (e.g., 1000 ml. Water Fill Test, USP Iodine Test), and general biocompatibility testing protocols.

• The sample size for the training set:

  • Not applicable. This device is not an AI/machine learning product and therefore does not have a "training set" in that context. The "training" here would be for the manufacturing process to consistently produce compliant gloves.

• How the ground truth for the training set was established:

  • Not applicable, as there is no "training set" in the AI sense. The manufacturing process is designed and controlled to meet the established performance standards.
