ISO 14184-2:2011规定了通过蒸汽吸收法测定任何形式的纺织品在加速储存条件下释放的甲醛量的方法。
本程序适用于通过本方法测定的织物上可释放甲醛的范围为20 mg/kg至3500 mg/kg。下限为20毫克/千克。低于此限值时,结果报告为“无法检测”。
ISO 14184-1:2011给出了一种测定游离甲醛和部分通过水溶液水解提取的甲醛的方法。
ISO 14184-2:2011 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 3 500 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 14184-1:2011.
