18、ion 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 member body interested in a subject for which a technical committee has been established h
19、as 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 Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Int
20、ernational 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 adopted by the technical committees are circulated to the member bodies for voting. Public
21、ation 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 patent rights. ISO shall not be held responsible for identifying any or all such patent ri
22、ghts. ISO 5403-1 was prepared by the European Committee for Standardization (CEN) Technical Committee CEN/TC 289, Leather, in collaboration with the Physical Test Commission of the International Union of Leather Technologists and Chemists Societies (IUP Commission, IULTCS), in accordance with the Ag
23、reement on technical cooperation between ISO and CEN (Vienna Agreement). IULTCS, originally formed in 1897, 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 establishin
24、g international methods for the sampling and testing of leather. ISO recognizes IULTCS as an international standardizing body for the preparation of test methods for leather. This first edition of ISO 5403-1 cancels and replaces ISO 5403:2002, which has been technically revised. Subclause 5.3 has be
25、en revised and the formula in 7.2 has been corrected. The main reason for revision was to align part 1 with part 2 and editorial changes have therefore also been made.

28、r resistance of flexible leather Part 1: Repeated linear compression (penetrometer) 1 Scope This part of ISO 5403 specifies a method for determining the dynamic water resistance of leather by means of repeated linear compression. It is applicable to all flexible leathers but is particularly suitable
29、 for leathers intended for footwear applications. 2 Normative references The following referenced documents are indispensable 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 a
30、ny amendments) applies. ISO 2418, Leather Chemical, physical and mechanical and fastness tests Sampling location ISO 2419, Leather Physical and mechanical tests Sample preparation and conditioning ISO 3696:1987, Water for analytical laboratory use Specification and test methods 3 Principle A test pi
31、ece is formed into the shape of a trough and flexed while partially immersed in water. The time taken for water to penetrate through the test piece is measured. The method also allows for the percentage mass of the water absorbed and the mass of the water transmitted through the test piece to be det
32、ermined. NOTE This test method uses compression-type flexing, whereas the test method of ISO 5403-2 for water resistance imparts folding-type flexing on the leather specimens. Given the two completely different flexing actions, it is not possible to compare the results obtained from the two test met
33、hods. 4 Apparatus, reagents and materials Usual laboratory apparatus is required and, in particular, the following. 4.1 Test machine, including the parts described in 4.1.1 to 4.1.3. (See also Annex A.) 4.1.1 One or more pairs of cylinders, 30,0 mm 0,5 mm in diameter, made of inert rigid material, m
34、ounted with their axes horizontal and co-axial. One cylinder shall be fixed and the other moveable along the direction of its axis such that the maximum separation of the cylinders is 40,0 mm 0,5 mm.

36、cles/min and an amplitude of 1,0 mm 0,1 mm, 1,50 mm 0,15 mm, 2,0 mm 0,2 mm or 3,0 mm 0,3 mm about its mean position. NOTE The four amplitudes of the crank motion are such that the test piece is compressed by 5 %, 7,5 %, 10 % or 15 % respectively when the cylinders approach one another. 4.1.3 Tank, m
37、ade from non-corroding material, holding distilled or deionized water, in which the test piece can be partially immersed. The test machine may also include an electrical circuit that indicates when water has penetrated through the test piece. 4.2 Ring-shaped clamps, with internal diameter adjustable
38、 between 30 mm and 40 mm. 4.3 Press knife, the inner wall of which is a rectangle of 60 mm 1 mm 75 mm 1 mm, conforming to the requirements of ISO 2419. 4.4 Distilled or deionized water, of grade 3 in accordance with ISO 3696:1987. 4.5 Balance, weighing to 0,001 g. 4.6 Clock, reading to 1 s. 4.7 Abra
39、sive paper, grade P180, as defined in the P-series grit-size standard published by the Federation of European Producers of Abrasive Products, cut into rectangles of 65 mm 5 mm 45 mm 5 mm, fixed to a flat, rigid base of the same size and weighted to give a total mass of 1,0 kg 0,1 kg. A fresh piece o
40、f abrasive paper shall be used for each test. 4.8 Absorbent cloth, cut into rectangles of 120 mm 5 mm 40 mm 5 mm, machine washed prior to first use following the cycle recommended by the cloth manufacturer. A suitable cloth is terry towelling (frott) in 100 % cotton and weighing about 300 g/m2. The
41、absorbency of this material might not be optimal when new, and therefore the cloths shall be washed before the first use. 4.9 Auxiliary apparatus, to determine the stiffness of the test piece, consisting of one pair of cylinders of 30,0 mm 0,5 mm in diameter mounted with their axes horizontal and co
42、-axial, a means of moving the cylinders together, a means of measuring the reduction in distance between the cylinders, to the nearest 0,1 mm, and a means of measuring the force exerted along the axes of the cylinder to the nearest 5 N. 5 Sampling and sample preparation 5.1 Sample in accordance with
43、 ISO 2418. Cut four test pieces by applying the press knife (4.3) to the grain (or to the outer surface when worn). Cut two test pieces with the longer side parallel to the backbone and two test pieces with the longer side perpendicular to the backbone. If there is a requirement for more than two hi
44、des or skins to be tested in one batch, then only one test piece in each direction need be taken from each hide or skin, provided that the overall total is not less than two test pieces in each direction. 5.2 Prepare the four test pieces using the following method. Lightly buff the grain (or the out
45、er surface when worn) by placing the test-piece grain (or the outer surface when worn) upwards on a flat surface. Place the weighted abrasive paper (4.7) on the test piece and move the abrasive paper ten times backwards and forwards along the full length of the test piece without applying any more d
46、ownward force than is applied by the weighted abrasive. NOTE In some situations, it might be more appropriate to flex a sample for 20 000 cycles using the method and apparatus specified in ISO 5402-1.

This surface coat greatly increases the water resista
48、nce of the leather. If microcracks develop rapidly in this coat as a result of flexing during wear or the coat is damaged by abrasion, then measurements made on the leather as received can be misleading. The abrasion and flexing treatments described above are intended to simulate the abrasion which the leather would receive while being worn and the test piece should therefore be abraded or flexed before the test. The purpose of this abrasion is not to remove the surface coat but merely to scratch it lightly. 5.3 Store the test specimens in a standard controlle
