This document specifies a method for determining the colour fastness to perspiration of leather of all kinds at all stages of processing. It applies particularly to gloving, clothing and lining leathers, as well as leather for the uppers of unlined shoes.
Abstract
Overview
EN ISO 11641:2025 - Leather - Tests for colour fastness - Colour fastness to perspiration () specifies a laboratory method to assess how leather retains colour when exposed to human perspiration conditions. Adopted by CEN and prepared by IULTCS in collaboration with CEN/TC 289, this standard applies to leather at all processing stages and is particularly relevant for . The method simulates the more demanding alkaline perspiration environment to provide conservative, reproducible results.
