Full Description

1.1 This test method covers the determination of the dilute solution viscosity (DSV), the gel characteristics, and the swelling index of raw non-oil-extended and non-pigmented SBR and NBR.

1.2 This test method may be used to determine the DSV and gel characteristics of rubbers other than SBR and NBR, however, solvents other than 2-butanone and toluene may be required.

1.3 This test method is not intended for the measurement of micro-gel.

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
