17、 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-governmental, in liaison with ISO, also take part in the work. ISO collaborate

The method

28、is applicable to all types of leather of any tannage. The measurement is valid for both the whole leather and a test sample.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

30、ditioning3 PrincipleThe leather is placed in a gauge under a specified 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

31、, comprising the flat horizontal surface of a cylinder of diameter 10,00 mm 0,05 mm projecting 3,0 mm 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 otherwise presen

32、ts a convex surface to the presser foot. The anvil is raised 3 mm above the platform so that errors are avoided in measurements on 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 and capable of movement normal t

33、o the face of the anvil. The contacting surfaces of the anvil and presser foot shall be dead weight loaded with 393 g 10 g. Movements of the presser foot shall give a direct reading of the movement on the gauge (4.1.1).NOTE The loads and dimensions quoted in 4.1.3 give a pressure of 49,1 kPa (500 g/

34、cm2).4.1.4 Rigid stand, to hold the gauge (4.1.1), anvil (4.1.2) and presser foot (4.1.3).

Five measurements to be taken, distributed across the sample.5

35、.2 Sample prepared for other tests. Three measurements to be taken, distributed across the sample.5.3 Sample of unknown origin. Five measurements to be taken, distributed across the sample.5.4 For very heavy, firm leathers, a smaller sample is recommended to avoid curvature. Three measurements to be

36、 taken, distributed across the sample.5.5 For whole hides, five 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 be identified. If th

37、e grain cannot be identified place the sample in the gauge with either surface upwards. Apply the load 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

38、test report shall include the following:a) a reference to this International Standard, i.e. ISO 2589;b) the results obtained expressed to the nearest 0,01 mm;c) the standard atmosphere used for conditioning and testing as given in ISO 2419;d) any deviations from the method specified in this Internat
