Leather - Tests for colour fastness - Colour fastness to mild washing, Endorsement notice The text of the International Standard IS0 15703 : 1998 was approved by CEN as a European Standard without any modification. NOTE: Normative refer
17、ences to international publications are listed in Annex ZA (normative). Page 3 EN IS0 15703 : 1999 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
18、 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 provi

IUP 2, Sampling 3 Principle A composite specimen of the leather and an adjacent textile fabric is agitated
24、together with PTFE rods in a washing liquor, rinsed and then squeezed and dried. 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
25、 are in accordance with those described in IS0 105-A01, taking into account the differences between textile substrates and leather. 4 Apparatus and materials Ordinary laboratory apparatus and 4.1 Test apparatus), consisting of a rotating drum of capacity approximately 500 ml made typically of glass
26、or stainless steel and sealed using solvent-resistant rubber gaskets, for example. 4.2 PTFE rod+), 20 mm k 2 mm long, 7 mm to 9 mm in diameter. 4.3 Plain-weave fabric, measuring 1 O0 mm x 36 mm, for use as adjacent fabric.

NOTE 2 IS0 105-A04 and
28、 IS0 105-A05, this may be used instead of the visual assessment method. If a suitable instrumental system is available for measuring the change in colour in accordance with l) Examples of suitable apparatus available commercially are given in annex A. 2, Examples of commercial sources are given in a
29、nnex A. Page 5 EN IS0 15703 : 1999 5 Test specimen If the piece of leather available for testing is a whole hide or skin, then first take a sample in accordance with IUP 2. Take a specimen of leather measuring 100 mm x 36 mm which is representative of the piece of leather available for testing. NOTE
30、 3 If the same specimen of leather is required for other chemical or physical tests after the mild washing treatment, for example to assess the dimensional stability after mild washing, then a larger specimen will be more appropriate. Assemble the composite specimen by placing the piece of adjacent
31、fabric (4.3) over the leather specimen and attaching them together, for example by inserting two steel staples or stitching them together with a thread, at the narrow ends. Attach the adjacent fabric to the flesh side of grain leathers and to the side worn inside for other leathers. 6 Procedure 6.1
32、litre of water (4.5) and stirring vigorously until no solids are visible. Prepare a suitable quantity of washing liquor by adding 5,O g of detergent (4.4) to every 6.2 Place 100 ml of the washing liquor and 20 PFTE rods (4.2) in the drum (see 4.1), and warm to 30 OC f 2 OC. Place the composite speci
33、men in the drum and rotate at 40 rpm * 5 rpm for 30 min, maintaining the temperature at 30 OC f 2 OC. 6.3 Remove the washing liquor and replace it with 100 ml of water (4.5) at 30 OC k 2 OC (rinsing water). Rotate the drum at 40 rpm k 5 rpm for 10 min, maintaining the temperature at 30 OC k 2 OC. Re
34、peat that rinsing procedure once more with fresh rinsing water. 6.4 Remove the composite specimen from the drum, place it between sheets of blotting paper, and the blotting paper between glass plates. Place a weight of 4,5 kg on the upper glass plate and maintain the pressure for 1 min. Take the com
35、posite specimen out, unfasten one narrow end and place the composite specimen, opened out, on a horizontal grille so that the leather and adjacent fabric are not touching. Let the composite specimen dry in air under standard conditions as specified in IS0 2419 (20 OC k 2 OC and 65 % f 2 % RH). Stake
36、 the leather lightly. 6.5 Assess the change of colour of the grain side (or side worn outside) of the leather either visually in accordance with IS0 105-A02 or instrumentally in accordance with IS0 105-A05. 6.6 Assess the staining of the adjacent fabric either visually in accordance with IS0 105-A03
37、 or instrumentally in accordance with IS0 105-A04. 6.7 Note any changes in the leather finish, if applicable.
