The wo

18、rk of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governm

19、ental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The

20、main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.

21、Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 26082-1 was prepared by the European Committee for Standardization (CEN) Technical Committee CEN/

22、TC 289, Leather, in collaboration with the Physical Tests Commission of the International Union of Leather Technologists and Chemists Societies (IUP Commission, IULTCS) in accordance with the agreement on technical cooperation between ISO and CEN (Vienna Agreement). IULTCS, originally formed in 1897

23、, is a world-wide organization of professional leather societies to further the advancement of leather science and technology. IULTCS has three Commissions, which are responsible for establishing international methods for sampling and the testing of leather. ISO recognizes IULTCS as an international

24、 standardizing body for the preparation of test methods for leather. This first edition of ISO 26082-1 cancels and replaces ISO 26082:2007, which has been technically revised. It has a modified title and small changes have been made to 5.3, 5.7 and 6.2. ISO 26082 consists of the following parts, und

26、echanical test methods for the determination of soiling Part 1: Rubbing (Martindale) method 1 Scope This part of ISO 26082 specifies a method for determining the resistance of all forms of leather to visible soiling through repeated contact with soiled objects. It provides a physical pretreatment ro

27、utine for leathers that may be vulnerable to loss of soiling resistance while in service, prior to conducting further tests such as cleaning. 2 Normative references The following referenced documents are indispensable for the application of this document.

32、rposes 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 particular, the following. 5.1 Martinda

33、le 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 the specimen holder assembly is (795 10

34、) 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 mandrel device for specimen mounting, as d

35、efined 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 nominal pressure of 1,6 kPa on the test sp

36、ecimen 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 noted that this stroke differs from

37、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 another with a diameter of at least 3

38、8 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 is impregnated with a soilant mix of

39、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 mm, for the abrasion specimen holder

40、 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 diameter of at least 140 mm, for the abradi

41、ng table of the Martindale apparatus (5.1). BS EN ISO 26082-1:2012ISO 26082-1:2012(E) IULTCS/IUP 53-1:2012(E) ISO 2012 All rights reserved 35.9 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,

42、 or both. 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 te

43、st specimens, 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

44、testing 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 l

45、eather 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.

46、1 The soiling 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 wo

47、ol felt 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 shal

48、l be specified 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

49、 of approximately 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 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
