Description / Abstract:

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:

a) sulfur-modified types;

b) mercaptan-modified types;

c) types modified by other products.

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