14、SO 2589:2002(E) iv ISO 2002 All rights reservedForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each me

15、mber 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 closely with the International E

16、lectrotechnical 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. Draft International Standards ad

17、opted 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 document may be the subject of pa

18、tent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 2589 was prepared by the Physical Test Commission of the International Union of Leather Technologists and Chemists Societies (IUP Commission, IULTCS) in collaboration with the European Committee for Sta

19、ndardization (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 (Vienna Agreement). It is based on IUP 4 originally published in J. Soc. Leather Trades Chemists 42, p. 387, (1958) and d

20、eclared an official method of the IULTCS in 1959. An updated version was published in J. Soc. Leather Tech. Chem. 82, p. 225, (1998) and a further revision published in J. Soc. Leather Tech. Chem. 84, p. 311, (2000) and reconfirmed as an official method in March 2001. This latest revision now includ

22、RD ISO 2589:2002(E) ISO 2002 All rights reserved 1Leather Physical and mechanical tests Determination of thickness 1 ScopeThis International Standard specifies a method for determining the thickness of leather. The method is applicable toall types of leather of any tannage. The measurement is valid

23、for both the whole leather and a test sample.2 Normative referencesISO 2418Leather - Chemical, physical and mechanical and fastness tests Sampling locationISO 2419Leather - Physical and mechanical tests - Sample preparation and conditioning3 PrincipleThe leather is placed in a gauge under a specifie

24、d load for a specified time and the thickness read directly.4 Apparatus4.1 Test machine, including the following:4.1.1 Gauge, graduated to read to 0,01 mm directly with an accuracy of + 0,02 mm over the whole scale length.4.1.2 Anvil, comprising the flat horizontal surface of a cylinder of diameter

25、10,00 mm + 0,05 mm projecting 3,0mm + 0,1 mm above the surface of a concentric flat circular platform of diameter 50,0 mm + 0,2 mm.NOTE The circular platform of 50 mm diameter helps to support medium weight leathers which might otherwise presenta convex surface to the presser foot. The anvil is rais

26、ed 3 mm above the platform so that errors are avoided in measurementson heavy leathers which are not flat.4.1.3 Presser foot, having a flat circular surface of diameter 10,0 mm + 0,05 mm, coaxial with the anvil andcapable of movement normal to the face of the anvil. The contacting surfaces of the an

27、vil and presser foot shall bedead weight loaded with 393 g + 10 g. Movements of the presser foot shall give a direct reading of the movementon the gauge (4.1.1).NOTE The loads and dimensions quoted in 4.1.3 give a pressure of 49,1 kPa (500 g/cm2).The following referenced documents are indispensable

28、for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

30、 prepared for other tests. 3 measurements to be taken, distributed across the sample.5.3 Sample of unknown origin. 5 measurements to be taken, distributed across the sample.5.4 For very heavy, firm leathers, a smaller sample is recommended to avoid curvature. 3 measurements to betaken, distributed a

31、cross the sample.5.5 For whole hides, 5 measurements for each location should be taken.Condition all samples in accordance with ISO 2419.6 ProcedurePlace the apparatus on a flat, horizontal surface. Place the sample in the gauge grain side up if this can beidentified. If the grain cannot be identifi

32、ed place the sample in the gauge with either surface upwards. Apply theload gently and record the thickness 5 s + 1 s after full loading is reached.7 Expression of resultsThe results shall be expressed as the arithmetic mean and range to the nearest 0,01 mm.8 Test reportThe test report shall include
