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, a lower precision is to be
expected.
NOTE 2 This test method may be performed at other temperatures (i.e. 15 °C). When doing so, the density values of
water and isopropanol should be determined.
The pyknometer method shall be used as a reference method for determining the specific gravity and density
of bituminous binders.
WARNING — Use of this standard may involve hazardous materials, operations and equipment. This
standard does not purport to address all of the safety problems 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.
