The density and relative density of the test item were determined using a pycnometer with a volume of 10 mL. The density of the test item was calculated from the difference in weight between the full and empty pycnometer and its volume.
The volume of the pycnometer was determined first. The pycnometer was weighed empty.
Then it was filled with water, dried on the outside and weighed again. The temperature of the water was measured. The procedure was performed in duplicate. The mean volume of the pycnometer was calculated.
The pycnometer was filled with test item, dried on the outside and weighed. The temperature of the test item was measured. The test was performed in duplicate. The mean density and relative density of the test item were determined.
Measurements were performed at 20.0 ± 0.5°C. Weightings were performed on an analytical balance with an accuracy of 0.1 mg.
Interpretation
The density of a substance is the quotient of its mass and its volume and is expressed in SI units of kg/m3.
The relative density is the ratio between the mass of a volume of a substance to be examined, determined at 20°C, and the mass of the same volume of water, determined at 4°C. The relative density has no dimension.
A pycnometer was used for the determination of the density and relative density of ISO-MIX.
The density of the test item at 20ºC was 1.00 g/cm3(1.00 × 103 kg/m3).
The relative density was 1.00.
