ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those int
19、ended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see ww

23、 Technologists and Chemists Societies (IUF Commission, IULTCS) in collaboration with the European Committee for Standardization (CEN) Technical Committee CEN/TC 289, Leather, the secretariat of which is held by UNI, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienn
24、a Agreement).It is based on IUF 442 published in J. Sec. Leather Tech. Chem., 56, pp. 395-400 (1972) with a minor amendment in 65, p. 128 (1981), and declared an official method of the IULTCS in 1973 and reconfirmed in 1989.IULTCS, originally formed in 1897, is a world-wide organization of professio
25、nal leather societies to further the advancement of leather science and technology. IULTCS has three Commissions, which are responsible for establishing international methods for the sampling and testing of leather. ISO recognizes IULTCS as an international standardizing body for the preparation of
26、test methods for leather.This second edition cancels and replaces the first edition (ISO 15701:1998), which has been technically revised with the following changes: use of polymeric test materials other than poly(vinyl chloride) is allowed; change in title to reflect the use of polymeric test materi

28、stness Colour fastness to migration into polymeric material1 ScopeThis International Standard specifies a method for assessing the propensity of dyes and pigments to migrate from leather to a synthetic substrate by determining the transfer of colour from the leather to white plasticized poly(vinyl c
29、hloride) in contact with it.This method is suitable for leather of all kinds at any stage of processing.NOTE Tests to determine the transfer of colour from the leather using other polymeric materials (e.g. thermoplastic polyurethane) are also possible.2 Normative referencesThe following documents, i
30、n whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies.

32、her Chemical, physical and mechanical and fastness tests Sampling location3 PrincipleThe side under test of the leather specimen is placed on a polymeric sheet, for example a white-pigmented sheet of plasticized poly(vinyl chloride), and the resultant composite specimen is exposed to heat under pres
33、sure in a suitable apparatus. The transfer of colour from the leather to the white sheet is assessed with the standard grey scale for assessing staining and, if applicable, any change in hue of the staining is also assessed.The use of standard sheets of plasticized poly(vinyl chloride) makes it poss
34、ible to determine the tendency of colour to migrate from the leather to synthetic materials used in conjunction with the leather.If the leather has a finish, the test may be carried out with the finish intact or broken.The general colour fastness testing principles used are in accordance with those
35、described in ISO 105-A01, taking into account the differences between textile substrates and leather.4 Apparatus and materialsNormal laboratory apparatus and:4.1 Test apparatus, in which the composite specimen can be subjected, between glass plates, to a uniform pressure of (81,7 4,0) kPa using an a
36、pproximately 5 kg load weight. The pressure tolerance includes a maximal supplementary mass due to the glass plates of 250 g. The construction of the test apparatus shall ensure that the pressure is constant during the whole test. ISO 2015 All rights reserved 1BS EN ISO 15701:2015ISO 15701:2015(E)NO
37、TE 1 The 81,7 kPa pressure from a 5 kg load weight is equivalent to 833 g/cm2on the (30 20) mm leather specimen.NOTE 2 A test apparatus that allows removal of the load weight after fixing the composite specimens is not suitable for this test.NOTE 3 Examples of suitable apparatus available commercial
38、ly are given in Annex A.4.2 Oven, maintained at (50 2) C.4.3 Sheet of suitable polymeric material, preferably pigmented white.If no additional information is provided, use plasticized poly(vinyl chloride), pigmented white, (0,5 0,1) mm thick, measuring approximately 50 mm 30 mm.NOTE Examples of suit
39、able commercial sources for the prepared sheets of polyvinyl chloride and the specifications are given in Annex A.4.4 If the finish is to be broken, fine-grained abrasive paper, grade P180, as defined in the P-series grain size standard published by the Federation of European Producers of Abrasive P

41、ng with ISO 105-A03 or an instrumental system for assessing staining, complying with ISO 105-A04.5 Test specimens5.1 If the piece of leather available for testing is a whole hide or skin, then first take a sample in accordance with ISO 2418.5.2 If the leather has no finish, or if it has a finish but
42、 is to be tested with the finish intact, or the reverse side of the leather is to be tested, with the press knife (4.5) simply cut out a representative test specimen measuring 30 mm 20 mm.In case of a differing load weight, it is possible to realize the pressure stated in 4.1 either by adding a supp
43、lementary load (only possible for lower load weights) or by adjusting the dimensions of the specimen. The second possibility is restricted by the dimensions of the plasticized poly(vinyl chloride) sheet that has to exceed the dimensions of the test specimen.IULTCS/IUF 442:2015(E)2 ISO 2015 All right

The new area would be in this case of 5,4 cm2(27 mm 20 mm) instead of 6 cm2.5.3 If the le
46、ather has a finish and is to be tested with the finish broken, prepare the test specimen as follows:Cut out a piece of leather measuring approximately 80 mm 60 mm and lay it out, finish side down, on a sheet of abrasive paper (4.4), measuring about 150 mm 200 mm, held flat on a work surface. Load th
47、e upper side of the piece of leather uniformly with a 1 kg weight. Move the piece of leather 100 mm to-and-fro on the abrasive paper, carrying out 10 to-and-fro cycles.NOTE With practice, it is possible to achieve the same roughening effect holding the abrasive paper in the hand.Brush the roughened
48、area thoroughly to remove all dust. From the roughened area of the leather, use the press knife (4.5) to cut out a test specimen measuring 30 mm 20 mm.The fact that the finish has been broken shall be mentioned in the test report.5.4 Make up a composite specimen by placing the test specimen, with th
49、e side to be tested face down, in the centre of an approximately (50 30) mm piece of the plasticized poly(vinyl chloride) sheet (4.3).6 Procedure6.1 The load weight shall be preheated in the oven (4.2) at (50 2) C for at least 2 h. Place the composite specimen between two glass plates, place the plates in the apparatus (4.1) and load with an approximately 5 kg load weight corresponding to a pressure of (81,7 4,0) kPa on the leather.It is possible to test several composite specimens simultaneousl
