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 conditions

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

DevelopmentNote
Together with ISO 17226-1 supersedes ISO TS 17226. Also numbered as IULTCS/IUC 19-2. (05/2008) DRAFT ISO/DIS 17226-2 is also available for this standard. (08/2017)
