The UV aging test chamber originated in the United States and was later promoted worldwide, especially in the coatings and plastics industries. Currently, many national and international organizations have established relevant standards. The main and basic standards are ASTM G154 and ISO 4892. -3, ISO11507 three standards, which are introduced separately below.
ASTM G154: This standard is a standard published by the American Society for Testing and Materials. The current version is ASTM G154-06, which was formerly known as ASTM G53, which is a device-based standard and is now abolished. ASTM G154 is a basic standard for UV aging tests and is applicable to a variety of non-metallic materials. It specifies the requirements of the equipment and the test procedures. Several sets of test conditions are listed in the appendix, although these conditions are only for For reference, but because they are widely used in the industry, users generally choose from it. It should be noted that the conditions listed in the current version have irradiance values, which are indispensable when reporting results.
ISO 4892-3: This standard is a fluorescent UV lamp exposure test standard for plastics issued by the National Standardization Organization. It describes the test principle, specifies the requirements for the UV aging test chamber, three test methods and corresponding 6-level test conditions, unless It is also stipulated that these conditions are preferred, and the same six sets of conditions have irradiance regulations.
ISO11507: This standard is the fluorescent ultraviolet lamp exposure test standard for coatings issued by the National Standardization Organization. It describes the test principle and specifies two test methods. For the method A, the test conditions are specified, and there is no clear requirement for the irradiance. For Method B, only one test condition is recommended.
