This Part of GB/T 2912 specifies a method for determining the amount of formaldehyde released under the conditions of accelerated storage from textiles in any form by means of a vapour absorption method. This Part is intended for use in the range of releasable formaldehyde on the fabric between 20 mg/kg and 3500 mg/kg. The detection limit is 20 mg/kg. Below this limit the result is reported as "not-detectable".
