Textiles — Determination of formaldehyde — Part 3: Free and hydrolysed formaldehyde (extraction method) by liquid chromatography
纺织品甲醛的测定第3部分:液相色谱法测定游离和水解甲醛(萃取法)
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.
