Abstract

Overview

ISO 5433:2022 - Leather - Bovine wet blue - Specification defines requirements, sampling and test methods for bovine wet blue leather tanned primarily with basic chromium sulfate. This third edition (2022) replaces ISO 5433:2013 and provides standardized criteria for raw material, tanning, presentation, chemical limits, shrinkage temperature, fungicide use, sampling, testing, packaging and marking of wet blue bovine hides and parts.

Key topics and technical requirements

Tanning: Must use basic chromium sulfate as the primary tanning agent; visual inspection shall show complete penetration by the bluish chromium color. Tanning carried out at pH ≥ 3.0.
Shrinkage temperature: Measured per ISO 3380. Minimums: ≥ 85 °C for low chrome tannage and ≥ 100 °C for full chrome tannage. Chromic oxide content guidance links to these requirements.
Chemical requirements (Table 2):
- Volatile matter: > 50% of dry mass (or as agreed)
- Matter soluble in dichloromethane:
