ISO INTERNATIONAL STANDARD 105-Z03 First edition 1996-09-15 Textiles - Tests for colour fastness Part Z03: Intercompatibility of basic dyes for acrylic fibres Textiles Essais de solidité des teintures - Partie Zo3: Intercompatibilite des colorants basiques pour fibres acryliques ISO Referencenumber ISO 105-Z03:1996(E) ISO 105-Z03:1996(E) 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 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 Electrotechnical Commission (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 least 75 % of the member bodies casting a vote. International Standard ISO 105-Z03 was prepared by Technical Committee ISO/TC 38, Textiles, Subcommittee SC 1, Tests for coloured textiles and colorants. isO 105 was previously published in thirteen “parts", each designated by a letter (e.g.“Part A"), with publication dates between 1978 and 1985. Each designated “parts"” but retaining their earlier alphanumeric designations. A complete list of these parts is given in ISO 105-A01. @ISO1996 All rights reserved.

The This International Standard specifies a method for de- assessments are made using the scale showing the termining the behaviour of a basic dye in relation to its greatest difference in hue from that of the dye under compatibility with other basic dyes when applied to test. acrylic fibres in the presence of those basic dyes. The compatibility value of the dye is assessed by de- termining its dyeing behaviour in combination with 2 Normative reference each of a series of reference dyes in the relevant scale. The following standard contains provisions which, through reference in this text, constitute provisions of NOTE-- The recommended reference dyes have been this part of IsO 105.
