ISO/TS 17226:2003 specifies two methods for the determination of free and released formaldehyde in leathers. One method is relatively simple with regard to the laboratory equipment (colorimetric method), while the other needs more sophisticated equipment (HPLC method). The HPLC method is selective and not sensitive to coloured extracts.
