REAL DENSITY OF CALCINED PETROLEUM COKE: ASTM D2638
TEST SUMMARY
A sample is dried and ground to pass a 75- μm screen. The mass of the volume is determined directly, and the volume derived by the volume of helium displaced when the sample is introduced into a helium pycnometer. The ratio of the mass of the sample to the volume is reported as the real density.
TEST PRECISION
The test has a repeatability of 0.018 and reproducibility of 0.025 g/cm3.
Bias of this test method is not known.
