标准摘要
[中文适用范围]： 本文件规定了皮革中游离甲醛和释放甲醛的测定方法。 该方法基于比色分析，不适用于甲醛的精确定量。 甲醛含量是指在标准条件下从皮革中提取的水提取物中含有的游离甲醛和通过水解提取的甲醛的量。 该过程对甲醛不是绝对选择性的。 其他化合物（例如提取染料）可能会在 412 nm 处产生干扰。 [外文原描述]： This document specifies a method for the determination of free and released formaldehyde in leathers. This method, based on colorimetric analysis, is not intended to be used for a precise quantification of formaldehyde. The formaldehyde content is taken to be the quantity of free-formaldehyde and formaldehyde extracted through hydrolysis contained in a water extract from the leather under standard conditions. This process is not absolutely selective for formaldehyde. Other compounds such as extracted dyes could interfere at 412 nm.
