DESCRIPTION

BS EN ISO 17226-1:2021 - TC


This standard BS EN ISO 17226-1:2021 - TC Tracked Changes. 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 high-performance liquid chromatography (HPLC), is selective and not sensitive to coloured extracts and is intended to be used for 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 of use.
