BS ISO 2475:2011

This standard BS ISO 2475:2011 Chloroprene rubber (CR). General-purpose types. Evaluation procedure is classified in these ICS categories:

• 83.060 Rubber

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:

1. sulfur-modified types;

2. mercaptan-modified types;

3. types modified by other products.

For class c), the procedure for either a) or b) may be followed.
