ISO 17299-3:2014

Textiles — Determination of deodorant property — Part 3: Gas chromatography method

 

Introduction

This part of ISO 17299 describes a gas chromatography testing method for concentration measurement of odour chemicals in deodorant testing. This is the most general testing method that could be carried out in many testing laboratories globally if they have gas chromatography.

To avoid duplication, the major stream of the testing procedure is described in ISO 17299-1. This part of ISO 17299 describes a specific procedure for the gas chromatography testing method.

 

1   Scope

This part of ISO 17299 specifies a gas chromatography test method for the deodorant testing of all textile products. This method applies to the odour component chemicals, such as indole, isovaleric acid, nonenal, and acetic acid with added sodium chloride (NaCl). Two preparation methods are described in this test method:

— an odour chemical is applied in a container avoiding contact with a specimen in method A. Each chemical is tested separately;

— an odour chemical is injected directly on to the specimen in a container in method B. The chemicals tested in this method are a mixture of acetic acid and sodium chloride (NaCl).
