This document specifies gas chromatography (GC) test methods for the deodorant testing of all textile products. These methods apply to odour component chemicals, such as indole, isovaleric acid and nonenal.

Two methods are described in this document.

—   

Method A (single analysis) where an odour chemical is applied in a container avoiding contact with a test specimen.

—   

Method B (auto-regeneration) where an odour chemical is applied in a container avoiding contact with a test specimen multiple times to repeatedly challenge a test specimen.
