标准摘要
[中文适用范围]： 将纺织品样本（各种类型和各种形式的纺织品）暴露在密闭容器中的气态甲醛的作用下。 样本颜色的变化通过灰度来评估。 该方法不适用于评估在用脲醛产品进行防皱整理过程中或在随后用甲醛溶液进行染色处理过程中可能发生的颜色变化。 [外文原描述]： A specimen of the textile (textiles of all kinds and in all forms) is exposed to the action of gaseous formaldehyde in a closed container. The change in colour of the specimen is assessed with the grey scale. This method is not suitable for assessing changes in colour which may occur during crease-resist finishing with urea-formaldehyde products, or in subsequent treatment of the dyeing with solutions of formaldehyde.
