Mean density of test material = 1058.0 kg/m3
Density of water at 4.0°C = 1000.0 kg/m3
Relative density = 1058.0/1000 = 1.0580
Conclusion
The relative density of the test substance has been determined to be 1.0580 at 20.5 ± 0.5°C.
Comments
The density was calculated using the following formula:
Density = d x (c – a)/(b – a) kg/m3
a = mass of pycnometer (g)
b = mass of pycnometer and distilled water (g)
c = mass of pycnometer and test material (g)
d = density of water (kg/m3)
Description of key information
Relative density: 1.058 at 20.5 ± 0.5°C (EU Method A.3)
Key value for chemical safety assessment
- Relative density at 20C:
- 1.058
Additional information
A relative density value of 1.058 at 20.5± 0.5°C was determined for the substance using a pycnometer method in accordance with EU Method A.3 and in compliance with GLP. The result is considered to be reliable.
