Bitumen and bituminous binders. Measurement of density and specific gravity. Capillary-stoppered pyknometer method Ingestion-build-82396 PD IEC TR 62977‑2‑4 helps1 Scope This European standard specifies a procedure for determining the specific gravity and density of bituminous binders at (25,0 0,2) C using the capillary stoppered pyknometer method. Emulsions are excluded from the scope of this method. NOTE 1 This method can also be used for other hydrocarbon binders, for bituminous binders from other sources, e. g. recovered from asphalt or after hardening and for bituminous binders containing filler. However,
