4General principles
This document considers different types of leather intended for automotive upholstery, trims, such as steering-wheels/gear-knobs.
5 Sampling
5.1Laboratory samples shall be located and identified in accordance with EN ISO 2418.
5.2The number of leather samples shall be in accordance with ISO 2588, if not otherwise agreed by theparties.
6 Conditioning and sample preparation
Leather samples shall be conditioned and prepared for physical, mechanical and fastness tests in accordance with EN ISO 2419.
Leather samples for chemical tests shall be conditioned and prepared in accordance with EN ISO 4044.
7 List of test methods
The following tables define test methods which should be used to test automotive leather. The parameters to be tested are divided in fundamental properties (Table 1) and complementary properties (Table 2).
8 Test reports
The test reports shall contain at least the information defined in used standard test methods. The test reports should also include additional information (e.g. special evaluation of specimens) requested in specifications.
