适用范围：This part of ISO 17226 specifies a method for the determination of free and released formaldehyde inleathers. This method is based on colorimetric analysis.The formaldehyde content is taken to be the quantity of free-formaldehyde and formaldehyde extractedthrough 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 couldinterfere at 412 nm
