20、700:1999 BSI 03-2000 iii Foreword 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 member body interested i
21、n 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 Electrotechnical Commis
22、sion (IEC) on all matters of electrotechnical standardization. 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 least75% of the member bodies casting a vote. Internationa
23、l Standard ISO15700 was prepared by the Fastness Tests Commission of the International Union of Leather Technologists and Chemists Societies (IUF Commission, IULTCS). It is based on IUF420 published in J.Soc.Leather Tech. Chem.,59, p.99(1975), and declared an official method of the IULTCS in1975. An
24、nex A of this International Standard is for information only.iv blankENISO15700:1999 BSI 03-2000 1 1 Scope This International Standard specifies a method for assessing the effect, on leather of all kinds, caused by spotting with water. The method is suitable for assessing the change in physical appe
25、arance and the colour change of the leather. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the editions indicated were valid. All standards are subject to revi
26、sion, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below.

28、y scale rating. ISO3696:1987, Water for analytical laboratory use Specification and test methods. 3 Principle Two drops of distilled water are placed at separate spots on the leather. After30min, any surplus water is removed with filter paper from one of the drops and any physical effects are observ
29、ed. The other drop is allowed to evaporate overnight and the change in colour of the leather is assessed with the standard grey scale. Since the finish of a patent leather and other plastic coated leathers is impervious to water, an alternative procedure is required in which the water spot are place
30、d on the inside surface of the leather. The general colour fastness testing principles are in accordance with those described in ISO105-A01, taking into account the differences between textile substrates and leather. 4 Apparatus and materials Ordinary laboratory apparatus and 4.1 Pipette, to deliver
31、 water drops of approximately0,15ml. 4.2 Water, grade3 as defined in ISO3696. 4.3 Grey scale for assessing change in colour, in accordance with ISO105-A02. NOTE 1If a suitable instrumental system is available for measuring the change in colour in accordance with ISO105-A05, this may be used instead
32、of the visual assessment method. 5 Test specimen Take a specimen of leather, at least100mm 50mm in size, which is representative of the piece of leather available for testing. 6 Procedure (for patent leathers, seeclause7) 6.1 Place the specimen on a flat surface with the surface to be tested uppermo
33、st. Normally this will be the side corresponding to the outside of the leather article to be produced from the piece of leather. 6.2 With the pipette(4.1) place two drops (eachapproximately0,15ml) of water(4.2) approximately50mm apart on the surface of the specimen. 6.3 After30min remove the residua
34、l water (if any) from one spot by gently blotting with filter paper and note any physical effects the water has had on the leather. NOTE 2The physical effects which may be observed include swelling and loss of lustre. To detect these, it may be necessary to observe the leather from all directions. D
35、escribe the severity of the effect using one of the following terms: slight, moderate, or severe. 6.4 After allowing the specimen to stand for16h, assess, either visually in accordance with ISO105-A02 or instrumentally in accordance with ISO105-A05, the grey scale rating corresponding to the change
36、in colour of that part of the specimen which was spotted with the second drop. To assess the permanence of the colour change, subject the leather surface to a light manual treatment as described below and again assess the change in colour using the grey scale. (Subject the leather to the type of man
37、ual treatment normally applied by the end user to this type of leather. Forexample, polish shoe upper leathers lightly with a clear wax shoe polish, stake upholstery, gloving and clothing leathers lightly and brush suede leathers lightly.)EN ISO15700:1999 2 BSI 03-2000 7 Patent leathers and other pl
38、astic-coated leathers NOTE 3The wetting of such leathers from the back during use can cause ring-shaped marks or patches under the finish. However, such effects are not produced by applying water to the finished side of the leather, as in this International Standard, because patent leather finishes
39、are impervious to water. Therefore an alternative procedure is required for this type of leather. Test the fastness to water spotting of patent leather and other plastic coated leathers by wetting the inside surface of the specimen. Wet a small area with distilled water and, if necessary, aid wettin
40、g by rubbing in the water, for example, with a spatula. Continue adding water until it has penetrated through to the finished side or caused noticeable swelling. When this has happened, wait for30min and assess the effects on the leather as in6.3. 8 Effect of wear In particular situations, it may be
41、 informative to test the specimen after it has been subject to simulated wear. Pieces of leather may, forexample,first be subjected to a repeated flexing treatment in a suitable machine prior to testing for fastness to water spotting. 9 Test report The test report shall include the following informa
42、tion: a) a reference to this International Standard; b) a description of the type of leather tested; c) an indication as to which surface of the leather was tested; d) the physical effects of the water has had on the leather and the severity of each effect (see6.3); e) the grey scale method used and
43、 the grey scale rating obtained for the change in colour of the specimen before and after manual treatment (see6.4); f) the method of assessment and the grey scale rating obtained for the change in colour of the specimen before and after simulated wear, ifapplicable (seeclause8); g) details of any d
