Abstract

Overview

EN ISO 14931:2021 / ISO 14931:2021 - Leather for apparel (excluding furs) - Specifications and sampling procedures - is a CEN-adopted international standard that defines recommended values, test methods and sampling/conditioning procedures for apparel leather. The third edition (2021) updates limits for chemicals, adds mechanical requirements (tensile, elongation, stitch tear) and includes packaging and marking guidance. It supersedes EN ISO 14931:2015.

Key topics and technical requirements

The standard covers essential characteristics, associated test methods and recommended values for leather used in clothing (excluding furs). Important measurable requirements include:

Physical / mechanical
- Coating thickness ≤ 0.15 mm (ISO 17186)
- Tear load ≥ 15 N (ISO 3377-1)
- Tensile strength ≥ 12 N/mm2 and elongation 40–90 % (ISO 3376)
- Flexing resistance: aniline ≥ 20 000 cycles, pigmented finish ≥ 50 000 cycles (ISO 5402-1)
- Stitch tear resistance ≥ 40 N (ISO 23910)
Chemical / safety
- Chromium(VI)
