DIN EN ISO 105-E03:2010-08

This part of ISO 105 specifies a method for determining the resistance of the colour of textiles of all kinds and in all forms to the action of active chlorine in concentrations such as are used to disinfect swimming-pool water (break-point chlorination). Three alternative test conditions are specified. The active chlorine concentrations of 50 mg/l and 100 mg/l are intended for swimwear. The active chlorine concentration of 20 mg/l is intended for accessories such as beach robes and towels. A specimen of the textile to be tested is treated with a dilute chlorine solution of a given concentration and dried. The change in colour of the specimen is either assessed by comparison with the grey scale or instrumentally. Three alternative test conditions are specified. This document (EN ISO 105-E03:2010) has been prepared by Technical Committee ISO/TC 38 "Textiles", in collaboration with Technical Committee CEN/TC 248 "Textiles and textile products", the secretariat of which is held by the BSI (United Kingdom). The Committee responsible for this standard is NA 062-05-11 AA "Farbechtheit von Textilien - Deutsche Echtheitskommission DEK" ("Colour Fastness of Textiles - German Colour Fastness Committee") at DIN.
