Overview
This document gives guidelines to apply the available chemical test methods for leather. This information can be used by those involved in setting specifications for leather, especially for those parameters relating to restricted chemical substances. Lists of restricted chemicals contain many substances that are not relevant to the leather industry. Those chemical substances that are not mentioned in this document do not need to be determined, thus avoiding unnecessary analytical costs. This document (EN ISO 20137:2017) has been prepared by Technical Committee "International Union of Leather Technologists and Chemists Societies (IULTCS)" in collaboration with Technical Committee CEN/TC 289 "Leather", the secretariat of which is held by UNI (Italy). The responsible German standardization committee is Working Committee NA 062-05-52 AA "Chemische Prüfverfahren für Leder" ("Chemical test methods of leather") at DIN Standards Committee Materials Testing (NMP).
