1   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, 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.

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.
