Recommend any standards to follow for the face mask respiratory resistance test

Here are some specific standards and regulations that canbe followed for the face mask respiratory resistance test:

 

1. ASTM F3502 - Standard Test Method for Respirator Fit Capability for Negative Pressure Half-Facepiece Particulate Respirators

2. EN 149:2001+A1:2009 - Respiratory protective devices - Filtering half masks to protect against particles - Requirements, testing, marking

 

3. GB 2626-2019 - Respiratory protection - Non-powered air-purifying particle respirator

 

4. NIOSH 42 CFR Part 84 - Respiratory Protective Devices

 

5. ISO 16900-1:2019 - Respiratory protective devices - Methods of test and test equipment - Part 1: Determination of inward leakage and total inward leakage

 

These standards and regulations provide guidance on the test methods, equipment, and procedures for measuring the respiratory resistance of face masks and respirators. Following these standards can help ensure that the test results are accurate, reliable, and consistent across different testing facilities. Additionally, compliance with these standards may be required by regulatory bodies such as the Occupational Safety and Health Administration (OSHA) in the United States or the European Committee for Standardization (CEN) in the European Union.
