DESCRIPTION

BS EN ISO 17226-2:2019


This standard BS EN ISO 17226-2:2019 Leather. Chemical determination of formaldehyde content is classified in these ICS categories:
  • 59.140.30 Leather and furs

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.
