International Standard ISO 105-A02 was prepared by Technical Committee ISO/TC 38, Textiles, Sub-Committee SC 1, Tests for coloured textiles and colorants. This fourth edition cancels and replaces the third edition (ISO 105-A02:1987), of which it constitutes a minor revision. 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 part contained a series of "sections", each designated by the re- spective part letter and by a two-digit serial number (e.g. "Section Ao1"). These sections are now being republished as separate documents, them- nations. A complete list of these parts is given in ISO 105-A01. ISO 1993 All rights reserved.
