Leather - Chemical determination of formaldehyde content - Part 2: Method using colorimetric analysis (ISO 17226-2:2008); German version EN ISO 17226-2:2008


DIN EN ISO 17226-2-2008 发布历史

This part of ISO 17226 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 conditions. This process is not absolutely selective for formaldehyde. Other compounds such as extracted dyes could interfere at 412 nm.

DIN EN ISO 17226-2-2008由德国标准化学会 DE-DIN 发布于 2008-08,于 2009-09 废止。

DIN EN ISO 17226-2-2008 在中国标准分类中归属于: Y45 皮革加工与制品综合,在国际标准分类中归属于: 59.140.30 皮革和裘皮。
