Specifies the test methods for contamination of vulcanized or thermal plasticity rubber when it comes into contact with organic materials (e.g. paints, varnishes, plastics, etc.). The standard provides three test methods: contact dyeing and migration dyeing, extraction dyeing and penetration dyeing. These methods evaluate the dyeing and contamination effects of rubber materials on organic materials to help understand the performance of rubber in actual use. The update of the standard mainly involves the revision of references and test methods to ensure the accuracy and applicability of the test. Through these methods, users can systematically evaluate the performance of rubber products under various environment conditions.
