标准编号 Standard/Code标准名称 Standard Title
EN ISO 17226-2Leather - Chemical determination of formaldehyde content - Part 2: Method using colorimetric analysis (ISO 17226-2:2018)


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.

Test Requirement 测试要求:

FORMALDEHYDE 甲醛

Sample Size 样品数量 / 送样规格: 2pcs / 4 * A4 size
