Relación con otras normas DIN:
This part of ISO 17226 specifies a method for determination of free and released formaldehyde in leathers. This method is based on High Performance Liquid Chromatography (HPLC). It is selective and not sensitive to coloured extracts. 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. When compared with ISO 17226-2, the two analytical methods should give similar trends but not necessarily the same absolute result. Therefore, in the case of dispute, this method (ISO 17226-1) shall be used in preference to ISO 17226-2.
