GB/T 11039.2-2005 Focused Spinning & weaving products are resistant to gas fumigation air pollutants colour fastness test. This standard specifies the test method, specifies the parameter settings of test equipment, such as gas fumigation devices, and details the treatment process of Spinning & weaving products in gas fumigation environments, including key conditions such as fumigation time, gas concentration, temperature, and rigorous result evaluation methods. According to this standard test, it can accurately judge the stability of Spinning & weaving products in air pollution environments such as gas fumigation, and provide a key basis for Spinning & weaving enterprises to control product mass and evaluate the applicability of products in relevant environments.
