ISO 15703 pdf download.Leather — Tests for colour fastness — Colour fastness to mild washing 1 Scope This International Standard specifies a method for determining the resistance of leather to mild washing under specified conditions. The method is 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 leather preparation for assessing the change in any other physical or chemical property during mild washing. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below.

The change in colour of the leather and the adjacent textile fabric are assessed with the standard grey scales and, if applicable, any changes in the finish are noted. The general colour fastness testing principles used are in accordance with those described in ISO 1 05-A01 , taking into account the differences between textile substrates and leather. 4 Apparatus and materials Ordinary laboratory apparatus and 4.1 Test apparatus 1 ) , consisting of a rotating drum of capacity approximately 500 ml made typically of glass or stainless steel and sealed using solvent-resistant rubber gaskets, for example. 4.2 PTFE rods 2) , 20 mm ± 2 mm long, 7 mm to 9 mm in diameter. 4.3 Plain-weave fabric, measuring 1 00 mm x 36 mm, for use as adjacent...
