This document specifies a thermal pre-ageing procedure for leather to obtain indications about the tendency to the formation of hexavalent chromium under specified conditions and the determination of hexavalent chromium according to ISO 17075‑1 or ISO 17075‑2. This thermal pre-ageing procedure does not simulate any real condition in leather production or use. It is applicable to all types of chromium tanned leather.
Abstract
Overview
ISO 10195:2018 - Leather - Chemical determination of chromium(VI) content in leather - Thermal pre-ageing of leather and determination of hexavalent chromium - specifies a controlled thermal pre-ageing procedure to assess the tendency of chromium‑tanned leather to form hexavalent chromium (chromium(VI)). The standard defines how to pre-age leather samples thermally and then determine chromium(VI) levels using the established chemical methods in ISO 17075‑1 (colorimetric) or ISO 17075‑2 (chromatographic). It is applicable to all types of chromium tanned leather and is intended as an indicator test rather than a simulation of real-use conditions.
Key topics and technical requirements
- Purpose: Provide indications of a leather’s tendency to develop hexavalent chromium after thermal stress.
- Pre‑ageing conditions: Two defined temperature regimes:
- (60 ± 2) °C, relative humidity physically
