This document includes 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. When compared with EN 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 (EN ISO 17226-1) should be used in preference to EN ISO 17226-2. The formaldehyde content is taken to be the quantity of formaldehyde contained in a water extract from the leather.
