ISO 17299-6:2025

Overview

ISO 17299-6:2025 specifies standardized gas chromatography (GC) methodologies for evaluating the deodorant property of all textile products. Developed by the International Organization for Standardization (ISO), this document is part of a broader series focusing on odour neutralization in textiles. The GC test method outlined in ISO 17299-6:2025 uses automated dosing and sampling procedures to accurately assess textile deodorization performance against representative odour component chemicals such as indole, isovaleric acid, and nonenal. Two test methods are detailed: Method A (a single analysis) and Method B (auto-regeneration), providing comprehensive approaches for assessing odour reduction capabilities.

Key Topics

• Deodorant Property Determination: The standard outlines robust test methods for quantifying the ability of textiles to reduce or neutralize unpleasant odours.
• Odour Component Chemicals: Specific focus is given to chemicals such as indole (excrement odour), isovaleric acid (sweat/body odour), and nonenal (body odour), representing common sources of odour in textiles.
• Automated Gas Chromatography: Employs automated dosing and headspace sampling, promoting reproducibility and accuracy in odour measurement.
• Test Methods:
  • Method A (Single Analysis): Involves a one-time exposure of the specimen to the odour chemical in a controlled container.
  • Method B (Auto-Regeneration): Repeatedly challenges the textile specimen with the odour chemical, simulating continued use and evaluating ongoing deodorant effectiveness.
• Calculation and Reporting: Clear guidance is provided for calculating odour reduction rates and compiling comprehensive test reports for compliance and quality assurance.

Applications

ISO 17299-6:2025 enables manufacturers, testing laboratories, and quality assurance teams to:

• Evaluate Textile Deodorant Efficacy: Objectively measure how effectively textiles neutralize odours using standardized, globally recognized methods.
• Product Development and Claims Verification: Support the development of high-performance odour-neutralizing textiles and substantiate marketing claims for deodorant properties.
• Quality Control: Facilitate batch testing and comparative analysis for clothing, uniforms, bedding, sportswear, and other textile products where odour control is critical.
• Research and Innovation: Provide a scientific foundation for innovations in deodorant textile technology by establishing a reliable, repeatable framework for laboratory testing.
• Compliance and Export: Assure international partners and customers that tested products meet established deodorization standards, simplifying global trade and regulatory acceptance.

Related Standards

• ISO 17299-3:2014 – Part 3: Gas Chromatography Method: Provides methodology for deodorant property determination using manual dosing and sampling, serving as a basis for comparison with the automated approach in Part 6.
• ISO 139 – Textiles: Standard Atmospheres for Conditioning and Testing: Specifies environmental conditions for specimen preparation, essential for consistent and valid results.
• ISO 3696 – Water for Analytical Laboratory Use: Details the quality requirements for water used in analytical testing, ensuring reliability in preparation and cleaning.

ISO 17299-6:2025 is a key reference for deodorant testing of textiles, supporting manufacturers and laboratories in achieving certified, credible, and reproducible results for deodorant properties using advanced, automated gas chromatography procedures. For industries where odour management is important, this standard delivers significant practical value and confidence in product claims.
