The following ASTM standards are commonly used for air permeability testing:

1. ASTM D737 - Standard Test Method for Air Permeability of Textile Fabrics: This standard applies to air permeability testing of fiber fabrics and fabric composites.

2. ASTM E398 - Standard Test Method for Water Vapor Transmission Rate of Sheet Materials Using Dynamic Relative Humidity Measurement: This standard applies to the water vapor transmission rate test of materials such as films and sheets. This standard applies to the testing of water vapor transmission rate of materials such as film and sheet.

3. ASTM F2476 - Standard Test Method for the Determination of Carbon Monoxide Concentrations in Enclosed Atmospheres Using Length of Stay and Breathing Rate Adjusted Dosages: This standard applies to the testing of water vapor transmission rate of materials such as film and sheet. Rate Adjusted Dosages: This standard applies to the test for analyzing carbon monoxide concentrations in enclosed spaces.

4. ASTM C522 - Standard Test Method for Airflow Resistance of Acoustical Materials: The scope of this standard includes testing of airflow resistance of acoustical materials.

The above standards are commonly used for air permeability testing in a variety of fields, and it is important to understand the specifics of the standard and its scope of application before using it to ensure that the test is accurate and effective.

In addition, depending on the material and application requirements, there are other ASTM standards related to air permeability testing, such as:

- ASTM D726 - Standard Test Method for Air Permeability of Plastic Film and Sheet Materials.

- ASTM E96 - Test Method for Water Vapor Transmission Rate Applicable to Surface Packaging Materials, Paper, and Other Materials.

- ASTM E2178 - Standard Test Method for Measuring Air Permeability of Composite Materials or Textiles.

- ASTM F1868 - Standard Test Method for Measurement of Moisture Vapor Transmission Rate of Man-Made Materials such as Plastics and Textiles.

These standards are based on different material types and application areas. When performing air permeability testing, it is recommended that the applicable ASTM standard be selected for testing based on the actual situation. Please note that the version and scope of application of the standards may be updated, so please select the relevant latest version as required.
