CAS number: 13784-51-5
Calibration and validity verification
The calibration was carried out on August
The measured density of the calibration
liquids at 20°C is mentioned in table 1. Also the deviation from the
literature values is mentioned. The mean value for the calibration
liquids agrees within ± 0.002 g/cm3(accuracy range) with
the literature values.
Table : measured density of calibration
liquids at 20°C
Mean density value [g/cm3]
Deviation from literature value [g/cm3]
The validity of the method was verified
prior to the measurement with the test substance using demineralized
Measured density of water at 20°C:
measurement 1: 0.9982 g/cm3
measurement 2: 0.9982 g/cm3
measurement 3: 0.9982 g/cm3
values agree within ± 0.0005 g/cm3with the literature
value for demineralized water.
Density test substance
Measured density of the test substance at
measurement 1: 1.0512 g/cm3
measurement 2: 1.0513 g/cm3
measurement 3: 1.0516 g/cm3
Mean value at 20°C is 1.0514 g/cm3.
The standard deviation is ± 0.0002 g/cm3.
The relative density (D420),
is the ratio of the true density of a material at a temperature of 20ºC
and the density of water at a temperature of 4ºC (density = 0.999975g/cm3).
The relative density has no dimension.
The relative density (D420) is
relative density of
