ISO 2781:2008 specifies two methods of test for the determination of the density of solid vulcanized and thermoplastic rubbers.

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 material.

The standard does not cover the determination of the relative density of rubber, which is the ratio of the mass of a gi ## Source - https://isopublicstorageprod.blob.core.windows.net/opendata/_latest/iso_deliverables_metadata/csv/iso_deliverables_metadata.csv Last verified: 2026-08-05.
