DIN EN 15326-2009 沥青和沥青粘合剂.密度和比重的测量.毛细管塞比重瓶法(包括修改件A1-2009).英文版本DIN EN 15326-2009-08
Bitumen and bituminous binders - Measurement of density and specific gravity - Capillary-stoppered pyknometer method(includes Amendment A1:2009); English version of DIN EN 15326:2009-08
This European standard specifies a procedure for determining the specific gravity and density of bituminous
binders at (25,0 + 0,2) ℃ 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 ℃). 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.
