Foreword

This standard mainly refers to the use of the Japanese Industrial Standard JISL0888..1998 "light, sweat composite color fastness test method" part of the content. This standard specifies two test methods, A and B, among which. a) The A method replaces the light and sweat glass containers specified in GB/T 14576-1993 with a film. The selected film has acid resistance and resistance. Alkaline, heat resistance and light transmittance meet the requirements of relevant standards for light resistance test; b) The B method replaces the multi-layer standard white cloth specified in GB/T 14576-1993 with the sample plate, which is economical and can reach the test. effect. This standard is proposed and managed by the National Certification and Accreditation Administration. This standard was drafted. Tianjin Entry-Exit Inspection and Quarantine Bureau of the People's Republic of China. The main drafters of this standard. Liu Hong, Wang Huimin. This standard is the first published industry standard for inspection and quarantine. Import and export textiles are resistant to light and sweat Fastness test method

1 Scope

This standard specifies the test method for the color fastness to light and sweat of imported and exported textiles. This standard is applicable to the determination of the light fastness of imported and exported textiles under the action of acid and alkali sweat.
