Mean density of test material: 1013.8 kg/m³
Density of water at 4.0 °C: 1000.0 kg/m³
Relative density of test material: 1013.8 / 1000.0 = 1.0138
The density was calculated using the following formula: Density = d x [(c-a) / (b-a)] kg/m³
Where:
a = Mass of pycnometer (g)
b = Mass of pycnometer and distilled water at 20.0 °C (g)
c = Mass of pycnometer and test material at 20.0 °C (g)
d = Density of water at 20.0 °C (kg/m³)
Description of key information
The relative density of the test item at 20 °C (compared to water at 4 °C) is D20/4 = 1.0138.
Key value for chemical safety assessment
- Relative density at 20C:
- 1.014
