Foreword

This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part 1.Structure and Drafting Rules of Standardization Documents". Drafting. This document supersedes GB/T 20382-2006 "Determination of Carcinogenic Dyes in Textiles" and GB/T 20383-2006 "Sensitizing Dyes in Textiles". "Determination of Disperse Dyes". This document is based on GB/T 20382-2006, and integrates the content of GB/T 20383-2006, and... Compared with GB/T 20382-2006, apart from structural adjustments and editorial changes, the main technical changes are as follows. ---The principle has been changed (see Chapter 4, Chapter 3 of the.2006 edition); ---Reagents and materials have been changed (see Chapter 5, Chapter 4 of the.2006 edition); ---The instruments and equipment have been changed (see Chapter 6, Chapter 5 of the.2006 edition); ---The experimental procedures have been changed (see Chapter 7, Chapter 6 of the.2006 edition); ---The formulas for calculating the content of each target sensitizing, carcinogenic, and other dyes have been changed (see Chapter 8, Chapter 7 of the.2006 edition); ---The limits of quantitation have been changed (see 9.1, 8.1 in the.2006 edition); ---Precision has been revised (see 9.2, 8.2 in the.2006 edition); ---The content regarding sensitization, carcinogenicity, and other dyes has been revised (see Appendix B, Appendix A of the.2006 edition). This document is modified to adopt ISO 16373-2.2014 "Textiles - Dyes - Part 2.Extractable dyes including sensitizing and carcinogenic dyes". The dye was determined using a general method (using the pyridine-water method).
