標(biāo)準(zhǔn)簡介

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.nd edition 2018-12 Leather — Chemical determination of formaldehyde content — Part 1: Method using high performance liquid chromatography Cuir — Dosage chimique du formaldéhyde — Partie 1: Méthode par chromatographie en phase liquide à haute performance Reference numbers ISO 17226-1:2018(E) IULTCS/IUC 19-1:2018(E) ？ ISO 2018 ISO 17226-1:2018(E) IULTCS/
