The work of preparing International Standards is normally carried out through IS

17、O 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-governmental, in liaison with ISO, also take part in the work. ISO collaborates c

18、losely 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 main task of technical committees is to prepare International Standards. Dra

19、ft 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.Attention is drawn to the possibility that some of the elements of this docum

20、ent may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.ISO 17130 was prepared by the European Committee for Standardization (CEN) Technical Committee CEN/TC 289, Leather, in collaboration with the Physical Tests Commission of the Inte

21、rnational 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, is a worldwide organization of professional leather societies to further the a

22、dvancement of leather science and technology. IULTCS has three Commissions, which are responsible for establishing international methods for the sampling and testing of leather.

26、 Sampling locationISO 2419, Leather Physical and mechanical tests Sample preparation and conditioningISO 17228, Leather Tests for colour fastness Change in colour with accelerated ageing3 PrincipleA conditioned test piece is aged using the conditions defined in ISO 17228. The shrinkage is determined

27、 after reconditioning.4 Apparatus and materials4.1 Oven, as specified in ISO 17228.4.2 Climate chamber, as specified in ISO 17228.4.3 Vernier calliper, reading to 0,1 mm.4.4 Support, glass plate covered with a polyester nonwoven fabric (as specified in ISO 105-B06).NOTE The glass plate support keeps

28、 the test piece flat and the polyester fabric stops the test piece from sticking to the glass.4.5 Press knife, square, as specified in ISO 2419 with inner walls measuring 150 mm 1 mm.4.6 Indelible marker.5 Sampling and sample preparation5.1 Sample in accordance with ISO 2418.

ISO 2013 All rights reserved 1BS EN ISO 17130:2013ISO 17130:2013(E)NOTE For some applications, it can be necessary to use larger test pieces e.g. (300 300) mm to

30、 enhance the accuracy, especially in the case of low shrinkage.5.2 Using an indelible marker (4.6), mark the lines and measurement reference points A, B, C and D on the test pieces.

31、urement reference points on a test pieceIf test pieces with another dimension, e.g. (300 300) mm, are used, a square should be marked with a distance to each edge of (25 1) mm.5.3 Condition the test pieces in accordance with ISO 2419 for at least 48 h.6 Procedure6.1 Measure the distances AB, CD, AC

32、and BD on each test piece using the vernier calliper (4.3).6.2 Preheat the oven (4.1) to the test temperature or adjust the climate chamber (4.2) to the starting conditions. Place the test pieces with the grain side, top side or coated side downward on the support (4.4) in the centre of the oven or

33、climate chamber.To allow a fast exchange of humidity, it is necessary to place the leather in such a way that an intensive contact of the air in the oven or climate chamber with the flesh side of the leather is guaranteed.6.3 Age the test pieces as described in ISO 17228.6.4 If required, measure the

34、 distances between the measurement points following the description in 6.1 immediately after ageing (not later than 5 min). In this case, report that the measurement was made immediately.IULTCS/IUP 55:2013(E)2 ISO 2013 All rights reservedBS EN ISO 17130:2013ISO 17130:2013(E)6.5 Recondition the test
