ISO 17234-2 Extraction of Azo Dyes Using Liquid Chromatography Laboratory Testing Service Provided by Eurolab: A Comprehensive Guide

ISO 17234-2 is an international standard developed by the International Organization for Standardization (ISO) to provide a methodology for the extraction and analysis of azo dyes using liquid chromatography. The standard is part of the ISO 17234 series, which focuses on the determination of colorants in textiles and other materials.

Legal and Regulatory Framework

The legal and regulatory framework surrounding ISO 17234-2 Extraction of Azo Dyes Using Liquid Chromatography testing is governed by various national and international standards. In the European Union (EU), for example, Regulation (EC) No. 1907/2006 (REACH) requires manufacturers to provide safety information on their products, including textiles. This regulation also mandates the use of specific methods for analyzing substances in textiles.

International and National Standards

ISO 17234-2 is a widely recognized standard that has been adopted by various national standards organizations worldwide. Some examples include:

  • ASTM D5630 (Standard Test Method for Determination of Colorants in Textiles)

  • EN ISO 17234-2:2019 (Determination of colorants in textiles and other materials Part 2: Liquid chromatography method)

  • TSE EN ISO 17234-2:2019 (Turkish Standard for the determination of colorants in textiles and other materials using liquid chromatography)

    • Standard Development Organizations

    ISO 17234-2 was developed by a committee consisting of experts from various industries, including textile manufacturers, testing laboratories, and regulatory bodies. The standard is reviewed and updated periodically to reflect advances in technology and changing regulations.
