标准范围

ISO 17226-2:2008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。甲醛含量是指在标准条件下，通过水解从皮革中提取的水提取物中提取的游离甲醛和甲醛的量这个过程对甲醛不是绝对有选择性的。其他化合物，如提取染料，在412nm处可能会产生干扰。

ISO 17226-2:2008 specifies a method for the determination of free and released formaldehyde in leathers. This method is based on colorimetric analysis.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 conditionsThis process is not absolutely selective for formaldehyde. Other compounds such as extracted dyes could interfere at 412 nm.
