CAN/CGSB 4.2 NO. 63.5-2016/ISO 14184-2:2011, IDT Textile Test Methods: Textiles - Determination of Formaldehyde - Part 2: Released Formaldehyde (Vapour Absorption Method)
: Brown Technical Book Store
This part of ISO 14184 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. The procedure is intended for use in the range of releasable formaldehyde on the fabric between 20 mg/kg and 3500 mg/kg when determined by this method. The lower limit is 20 mg/kg. Below this limit, the result is reported as "not detectable". A method for determination of free formaldehyde and formaldehyde extracted partly through hydrolysis in aqueous solution is given in ISO 14184-1.
