Are there some common fabric penetration testing standards for reference?

There are some common fabric penetration testing standards that you can refer to. These standards are developed by different standardization organizations to evaluate the permeability properties of fabrics. Here are a few common fabric penetration testing standards:

1. AATCC 127: This standard was developed by the American Association of Textile Chemists and Colorists (AATCC) to evaluate the water permeability of fabrics.

1. ISO 811: This standard is formulated by the International Organization for Standardization (ISO) to evaluate the liquid resistance and liquid permeability of fabrics.

1. ASTM D737: This standard is formulated by the American Society for Testing and Materials (ASTM) to evaluate the liquid resistance and liquid permeability of fabrics.

1. GB/T 4744: This standard is formulated by the Chinese national standard to evaluate the liquid resistance and liquid permeability of fabrics.

These standards provide detailed test procedures and requirements, including provisions on fluid pressure, test time, sample size, etc. According to your needs and the relevant requirements of the region, choose the appropriate standard for fabric permeability test. Please note that these are just some common standards, and you may need to conduct further research and selection according to the requirements of specific application fields and industries.
