ISO 3865:2020 pdf download.Rubber, vulcanized or thermoplastic — Methods of test for staining in contact with organic material
1 Scope
This document specifies three methods for estimating the staining of organic finishes (subsequently referred to as “organic material”) by vulcanized or thermoplastic rubber, as defined in Clause 3:
— method A: contact staining and migration staining;
— method B: extraction staining;
— method C: penetration staining;

3.1 contact staining
stain which occurs on the surface of the organic material directly in contact with the rubber
3.2 migration staining
stain which occurs on the surface of the organic material surrounding the contact area
3.3 extraction staining
stain which occurs on the surface of the organic material as a result of contact with a liquid containing leached out constituents of the rubber
3.4 penetration staining
stain which occurs on the surface of a veneer layer of an organic material which is bonded to the rubber surface
4 Principle
4.1 Method A — Determination of contact straining and migration staining
The rubber to be tested is placed in direct contact with the specified organic material and then exposed to heat and/or artificial light.
4.2 Method B — Determination of extraction staining
The rubber to be tested is subjected to a test liquid which afterwards contacts the organic material.
This may be followed by irradiation of the organic material.
