Air permeability testing is an important aspect of quality control in various industries, particularly those involving textiles and filtration. Several common industry standards and guidelines exist for conducting air permeability testing. Here are a few prominent ones:

1. ASTM D737: This standard, published by the American Society for Testing and Materials (ASTM), outlines the test method for measuring the air permeability of textile fabrics. It provides procedures for both constant pressure and variable pressure methods.

2. ISO 9237: The International Organization for Standardization (ISO) developed this standard for determining the permeability of fabrics to air. ISO 9237 specifies the test apparatus, sample preparation, test procedure, and calculation methods.

3. ISO 5636: Part 5: This ISO standard specifically focuses on air permeance of paper and board. It provides guidance on the measurement of air permeance using a Gurley-type tester or Bendtsen tester.

4. EN ISO 15496: This European standard covers the determination of air permeability of flexible packaging materials. It specifies testing conditions, equipment requirements, and sample preparation for conducting accurate measurements.

5. JIS L 1096: This Japanese Industrial Standard defines the test method for determining air permeability of textile fabrics. It details the apparatus, sample conditioning, and test procedures, as well as calculations for reporting the results.

It's important to note that specific industries may have additional standards or guidelines related to air permeability testing, depending on their particular applications and requirements. These standards help ensure consistency, accuracy, and reliability in evaluating the air permeability characteristics of various materials.
