Abstract
Overview
ISO 11641:2025 - Leather - Tests for colour fastness - Colour fastness to perspiration is an international test method for assessing how leather colours resist exposure to human perspiration. Prepared by IULTCS and ISO, this third edition defines a reproducible laboratory procedure that simulates alkaline (and optionally acid) perspiration and measures both colour change of the leather and staining of adjacent fabrics.
