1 Scope
This document specifies a method for determining the amount of free formaldehyde and
formaldehyde extracted partly through hydrolysis by means of an extraction method.
The method can be applied for the testing of textile fibres, fabrics or yarns.
NOTE This method, based on liquid chromatography (LC), is selective and not sensitive to
coloured extracts and is intended to be used for precise quantification of formaldehyde.
