ISO 2475:1999 PDF

This International Standard specifies, for general-purpose chloroprene rubbers (CRs):

• physical and chemical tests on raw rubbers;
• standard materials, standard test formulations, equipment and processing methods for evaluating the vulcanization characteristics.

General-purpose chloroprene rubbers fall into three broad classes based on the type of polymerization modifier used in their preparation:

• sulfur-modified types;
• mercaptan-modified types;
• types modified by other products.
