Results
Measurement chamber with a volume of Vc= 7.9970 cm3 and
an expansion chamber with a volume of Vr= 6.1927 cm3 were
used. Two test series with different weights were done at a temperature
of 20 °C. Results are show in Tables 1 and 2.

Mean density ρPR for the two test series is 1.57 g/cm3. Relative density (compared to water at 4 °C) is:
D4R= 1.57 ± 0.01
Description of key information
Relative density: 1.57 at 20 °C (OECD 109, air comparison pycnometer)
Key value for chemical safety assessment
- Relative density at 20C:
- 1.57
