30、E) 4 Terms and definitions For the purposes of this document, the following terms and definitions apply. 4.1 soiling change in colour of a leather specimen caused by rubbing a standard soiled fabric on the coated surface of the leather 5 Apparatus and materials Normal laboratory apparatus and, in pa

31、rticular, the following. 5.1 Martindale abrasion apparatus, as specified in ISO 12947-1. 5.2 Abrasion specimen holder heads, for the Martindale apparatus (5.1) as defined in ISO 12947-1. The holder shall be fitted with loading pieces so that the sum of the mass of the applied load and the mass of th

32、e specimen holder assembly is (795 10) g. This exerts a nominal pressure of 12 kPa on the test specimen during the test. Use the abrasion option that forms a Lissajous figure with a (60 1) mm stroke. 5.3 Pilling specimen holder heads, for the Martindale apparatus (5.1), including the auxiliary mandr

33、el device for specimen mounting, as defined in ISO 12945-2. The pilling specimen holder shall be fitted with ring weight and the nominal 12 kPa loading piece (as in 5.2), so that the sum of the mass of the applied load and the mass of the specimen holder assembly is (1 010 15) g. This exerts a nomin

34、al pressure of 1,6 kPa on the test specimen during the test. The use of the mandrel is necessary to correctly mount the soiling cloth on the holder and to avoid contact with the soiling surface of the cloth. Use the abrasion option that traces a Lissajous figure with a (60 1) mm stroke. It should be

35、 noted that this stroke differs from the standard machine setting for the textile pilling test. NOTE This might not be possible with all Martindale machines, particularly old machines. 5.4 Circular sample cutters, for the specimen and soiling cloth. One cutter with a diameter of at least 140 mm and

36、another with a diameter of at least 38 mm. 5.5 Standard soiling cloth, cut to a diameter of either at least 38 mm for the abrasion specimen holder of the Martindale apparatus (5.2), or at least 140 mm for the pilling specimen holder of the Martindale apparatus (5.3). The standard soiling test cloth

37、is impregnated with a soilant mix of carbon black and olive oil. Alternative soiling cloths can be specified by the client. NOTE Various standard soiling cloths are commercially available, see Annex A. 5.6 Polyetherurethane foam underlay, as specified in ISO 12947-1, cut to a diameter of at least 38

38、 mm, for the abrasion specimen holder of the Martindale apparatus (5.2). 5.7 Wool felt underlay, as specified in ISO 12945-2, cut to a diameter of (90 1) mm, for the pilling specimen holder (5.3). This is available pre-cut to size. 5.8 Wool felt underlay, as specified in ISO 12947-1, cut to a diamet

39、er of at least 140 mm, for the abrading table of the Martindale apparatus (5.1). 5DIN EN ISO 26082-1:2012-07 EN ISO 26082-1:2012 (E) 5.9 Grey scale for measuring change in colour, complying with ISO 105-A02, or an instrumental system for measuring change in colour, complying with ISO 105-A05, or bot

40、h. NOTE For very lightly coloured leather samples, it is more suitable to use the grey scale for measuring staining, complying with ISO 105-A03, or an instrumental system for measuring staining, complying with ISO 105-A04, or both. 6 Sampling and sample preparation 6.1 Prior to cutting the test spec

41、imens, condition the leather in accordance with ISO 2419. 6.2 Using the circular cutting device (5.4), cut two circular test specimens meauring not less than 140 mm in diameter out of the leather piece. Set aside one test specimen as the unsoiled reference. If the leather piece available for testing

42、 is a whole hide or skin, sample the test specimens in accordance with standard procedures given in ISO 2418. 7 Pretreatment wearing procedures In particular situations, at the clients request, it may be instructive to test the specimen after it has been subject to simulated wear. Pieces of leather

43、may, for example, first be subjected to a repeated flexing treatment in a suitable machine prior to the soiling testing. Or the leather test specimen may, for example, be subjected to an appropriate abrasion treatment prior to the soiling testing. 8 Procedure using a standard soiling cloth 8.1 The s

44、oiling procedure takes place on the abrading table of the Martindale abrasion machine (5.1). The leather test specimen backed with the wool felt underlay (5.8) is fitted on the abrading table (lower position) with the leather test side facing upwards. Check the leather specimen and backing wool felt

45、 are centrally positioned in the clamp of the abrading table. 8.2 The standard soiling cloth (5.5), backed with the appropriate underlay, shall be fitted to the specimen holder head (upper position) of the Martindale abrasion machine (5.1). The size of the specimen holder head to be used shall be sp

46、ecified by the client, either according to ISO 12945-2 for the larger pilling specimen holder head (5.3) with a circular soiling cloth surface of approximately 90 mm diameter, or according to ISO 12947-1 for the smaller abrasion specimen holder head (5.2) with a circular soiling cloth surface of app

47、roximately 28 mm diameter. NOTE 1 The larger size of the soiling cloth for the pilling holder means that normally heavier soiling will occur when this holder is used. However, the levelness of the soiling on the test specimen is considerably better and the larger size is the preferred option. Use a

48、piece of wool felt underlay (5.7) for the pilling specimen holder head. For the abrasion specimen holder head, use a new piece of foam underlay (5.6) for each change of the soiling cloth. Check that the machine settings for the Lissajous figure stroke is (60 1) mm. NOTE 2 The machine setting for the stroke of 60 mm is used for both sizes of the specimen holder. This gives a much better levelness of soiling on the specimen when compared with the 24 mm str
