Each member body interested in a subject for which atechnicalcommitteehasbeenestablishedhastherighttoberepresented 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 Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard ISO 105-Z06 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 part contained a series of "sections", each designated by the respective sections are now being republished as separate documents, themselves designated “parts" but retaining their earlier alphanumeric designations. A complete list of these parts is given in ISO 105-A01. Annex A of this part of ISO 105 is for information only. @ISO1998 All rights reserved.

The degree of migration is obtained by visual examination or by reflectance measurements. types of migration inhibitors, thickeners and electrolyte. The method may also be used to evaluate a pad liquor with which migration has been found on a continuous dye range. 2 Normative reference The following standard contains provisions which, through reference in this text, constitutes provisions of this part of IsO 105.
