29、emical, 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 pressure i

30、n 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 possible t

31、o 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 descri

32、bed 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 approxi

33、mately 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.4IDIN EN ISO 15701:2015-07 IEN ISO 15701:2015 (E) NOTE 1 The 81,7 kPa pressu

34、re 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 commercially are given in Annex A.

35、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 suitable commercial sources

36、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 Products (FEPA).NOTE FEPA

37、 Standard (43-1-2006), obtainable from FEPA (Federation of European Producers of Abrasives), 20 Avenue Reille, 75014 Paris, France. www.fepa-abrasives.org4.5 Press knife, the inner wall of which is a rectangle (30 1) mm (20 1) mm.4.6 Grey scale for assessing staining, complying with ISO 105-A03 or a

38、n 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 is to be tested with th

39、e 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 supplementary load (only pos

40、sible 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.5IDIN EN ISO 15701:2015-07IEN ISO 15701:2015 (E) A modality to rec

41、alculate the specimen area is given below.AmAm1100=()whereA0is the area of the specimen stated by this International Standard;A1is the recalculated area of the specimen;m0is the load weight stated by this International Standard;m1is the load weight existing in the laboratory.EXAMPLE If the available

42、 load weight m1is 4,5 kg, additional loading pieces of 0,5 kg are permitted to be added or a specimen with a different area is allowed to be used. The new area would be in this case of 5,4 cm2(27 mm 20 mm) instead of 6 cm2.5.3 If the leather has a finish and is to be tested with the finish broken, p

43、repare 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 the upper side of the piece of leather uniformly with a 1 kg weigh

44、t. 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 area thoroughly to remove all dust. From the roughened area of t

45、he 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 the side to be tested face down, in the centre of an approximately

46、 (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 l

47、oad weight corresponding to a pressure of (81,7 4,0) kPa on the leather.It is possible to test several composite specimens simultaneously, but care shall be taken to place each centrally between two plates so that pressure is exerted evenly over the specimen surfaces.6.2 Place the apparatus in the o

48、ven at (50 2) C for 16 h.NOTE Different test temperatures can be used as appropriate for assessing particular aspects of colour migration, such as for example the higher temperatures encountered in some processing procedures.6.3 On completion of the heat treatment, take the apparatus from the oven,

49、remove the load weight from the composite specimens and allow them to cool to room temperature.6.4 As soon as the composite specimens have cooled, separate them into their component elements and assess any staining of the plasticized poly(vinyl chloride) sheet with the grey scale (4.6).
