The work ofpreparing International Standards is normally carried out through ISOtechnical committees. Each member body interested in a subject for whicha technical committee has been established has the right to be representedon that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISOcollaborates closely with the International Electrotechnical Commission(IEC) on all matters of electrotechnical standardization.Draft International Standards adopted by the technical committees arecirculated to the member bodies for voting. Publication as an InternationalStandard requires approval by at least 75 % of the member bodies castinga vote.International Standard ISO 15700 was prepared by the Fastness TestsCommission of the International Union of Leather Technologists andChemists Societies (IUF Commission, IULTCS). It is based on IUF 420published in J. Soc. Leather Tech. Chem., 59, p. 99 (1975), and declaredan official method of the IULTCS in 1975.Annex A of this International Standard is for information only.SIST EN ISO 15700:2000

ISO 15700:1998(E)© ISO23PrincipleTwo drops of distilled water are placed at separate spots on the leather. After 30 min, anysurplus water is removed with filter paper from one of the drops and any physical effects areobserved. The other drop is allowed to evaporate overnight and the change in colour of theleather is assessed with the standard grey scale.Since the finish of a patent leather and other plastic coated leathers is impervious to water, analternative procedure is required in which the water spot are placed on the inside surface of theleather.The general colour fastness testing principles are in accordance with those described inISO 105-A01, taking into account the differences between textile substrates and leather.4Apparatus and materialsOrdinary laboratory apparatus and4.1Pipette, to deliver water drops of approximately 0,15 ml.4.2Water
