In the door and window industry, the quality and performance of EPDM strips are usually evaluated and certified according to the standards of different countries or regions. The following are the relevant standards of EPDM strips in the United States, the United Kingdom and China:
1. American standard: ASTM C864: This is a standard developed by the American Society for Testing and Materials (ASTM) to evaluate elastic strips for door and window sealing. This standard covers the requirements and test methods for the physical properties, weather resistance, tensile strength, and compression resistance of EPDM rubber strips.

2. British Standard: BS 4255: This is a standard issued by the British Standards Institution (BSI), which is used to evaluate the requirements and test methods of door and window seals. The BS 4255 standard covers the physical properties, weather resistance, tensile strength, compression resistance and other requirements of EPDM rubber strips.

3. Chinese standard: GB/T 14683: This is the standard issued by the National Standardization Administration of China, which is used to evaluate the technical requirements and test methods of door and window sealant strips. The GB/T 14683 standard covers the physical properties, weather resistance, tensile strength, compression resistance, and service life of EPDM strips.
These standards are widely used in the door and window industry in various countries or regions to ensure that the quality and performance of EPDM strips meet specific requirements. Door and window manufacturers and suppliers usually refer to these standards to select qualified EPDM strips and ensure that their products meet the corresponding technical standards and regulations. It should be noted that the specific applicable standards may vary according to different door and window types, uses and regions, so local codes and standard requirements should be referred to in specific applications.
