Abstract

Specifies two methods of test for the determination of the density of solid vulcanized rubber. Apparatus, time-interval between vulcanization and testing, conditioning of test pieces, procedures for the two methods, expression of results and test report are laid down. This Standard is identical with and reproduced from ISO 2781:1988.

Scope

This International Standard specifies two methods of test for the determination of the density of solid vulcanized rubber. Such determinations are of importance in the control of the quality of a rubber compound and in the calculation of the mass of rubber required to produce a given volume of vulcanizate. This International Standard does not cover the determination of the relative density of rubber, which is the ratio of the mass of a given volume of the rubber to the mass of an equal volume of pure water at a given temperature. In this International Standard the determination is made by observation of gravitationalforces underdifferent conditions but, for convenience, these forces are expressed in mass units.
