ISO 17299-4:2015

Textiles — Determination of deodorant property — Part 4: Condensation sampling analysis

 

Introduction

This part of ISO 17299 describes condensation sampling analyses to measure the very low concentration of the odour chemicals which is assumed at the level of human olfactory perception threshold.

 

1   Scope

This part of ISO 17299 specifies a deodorant testing method using analytical instruments after using condensation sampling methods for all textile products. This method is applicable to gaseous odour chemicals, such as indole, methyl mercaptan, hydrogen sulfide, isovaleric acid, and nonenal.

condensation sampling

method for collecting gaseous odour chemicals at very low concentration levels, which are then condensed by analytical methods to higher concentration levels to facilitate detections of the chemicals
