Comprehensive Guide to ISO 17234 Extraction and Analysis of Azo Colorants by HPLC Testing Service

Provided by Eurolab: Experts in Laboratory Testing and Certification

ISO 17234 is an international standard that governs the extraction and analysis of azo colorants by high-performance liquid chromatography (HPLC) testing. This standard is part of a broader family of ISO standards related to analytical chemistry, including ISO 17235 for textile colorants and ISO 17236 for dyes.

Legal and Regulatory Framework

The use of azo colorants in various industries, such as textiles, food, and pharmaceuticals, is regulated by national and international laws. The European Unions (EU) Cosmetics Regulation (EC) No. 1223/2009 prohibits the use of certain azo colorants due to concerns over their safety for human consumption. Similarly, the US FDA regulates the use of azo dyes in food products.

International and National Standards

ISO 17234 is an international standard developed by the International Organization for Standardization (ISO). It is based on a consensus among experts from various countries and industries. The standard has been adopted by several national standards organizations, including the European Committee for Standardization (CEN), the American Society for Testing and Materials (ASTM), and the Turkish Standards Institution (TSE).

Standard Development Organizations

The ISO 17234 development process involves a collaborative effort among experts from various countries and industries. The standard is maintained by the Technical Committee on Analytical Chemistry (TC 138) within the ISO.

Evolution of Standards

Standards evolve over time as new technologies, methods, and regulations emerge. New versions of standards are developed to reflect these changes and ensure that testing services remain relevant and effective.

Specific Standard Numbers and Scope

The following standard numbers are related to ISO 17234:

  • ISO 17234:2017 - Extraction and analysis of azo colorants by HPLC

  • ISO 17235:2017 - Textile colorants - Determination of color strength and color fastness (textiles, leather)

  • ISO 17236:2017 - Dyes - Determination of color strength and color fastness

    • Standard Compliance Requirements for Different Industries

    Industry-specific requirements for testing services include:

  • Cosmetics industry: EUs Cosmetics Regulation (EC) No. 1223/2009

  • Textile industry: EN ISO 17235, ASTM D1052-16
