ISO 17226-1:2008规定了测定皮革中游离和释放的甲醛的方法。该方法基于高效液相色谱（HPLC）。它是有选择性的，对着色提取物不敏感。 甲醛含量取自在标准条件下从皮革提取物中提取的游离甲醛和甲醛提取量

ISO 17226-1:2008 specifies a method for the 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.
