17、r- Tests for colour fastness - Colour fastness to machine washing, Endorsement notice The text of the International Standard IS0 15702 : 1998 was approved by CEN as a European Standard without any modification. NOTE: Normative references to international publications are listed in Annex ZA (normativ
18、e). Introduction In some countries, it has become customary to wash items containing leather components, such as sport shoes, rucksacks etc., in washing machines. Also labels on clothing that are washed in machines are sometimes made of leather. In order to assess leathers designed to be used for su
19、ch items, a machine washing test method has been developed. This International Standard assesses the colour fastness of such leathers under relatively severe conditions, using an alkaline detergent, which has been developed for textiles. It is not intended to replace IS0 15703, Leather - Tests for c
20、olour fastness - Colour fastness to mild washing, which assesses the colour fastness of leather to mild hand washing. The detergent specified in this International Standard contains a high percentage of phosphate, which may affect some leather dyes unfavourably and which is, for environmental reason
21、s, reduced or even banned from use in commercial textile detergents in many countries. But no other internationally agreed detergent is available and it fulfils the purpose of the test, which is to measure the colour fastness of leather to a process that is characteristic for textiles. As soon as su
22、ch an alternative detergent is agreed on internationally, a revision of this method will be considered. Page 3 EN IS0 15702 : 1999 1 scope This International Standard specifies a method for determining the resistance of leather to washing in a washing machine under specified conditions. The method i
23、s suitable for assessing the change in colour of the leather, the staining of an adjacent textile fabric and any change in the finish of the leather. This method can also be used in leather preparation for assessing the change in any other physical or chemical property during machine washing. 2 Norm
