The relative density of the test substance was determined to be 1.4071 ± 0.02935 (with 95 % confidence interval) at 20 °C with respect to water at 4 °C.

Conclusions:
The relative density of the test substance was determined to be 1.4071 at 20 °C with respect to water at 4 °C.
Executive summary:

The relative density of the test item was determined according to OECD TG 109, Regulation (EC) No 440/2008 method A.3 and OPPTS 830.7300 using the air comparison pycnometer method. Therefore the density was measured at a temperature of 20 °C ± 0.5 °C in 5 parallel tests. The mean relative density of the test item at 20 °C with respect to water at 4 °C was determined to be 1.4071 ± 0.02935 (with 95 % confidence interval).

Description of key information

The relative density of the test substance was determined to be 1.4071 at 20 °C with respect to water at 4 °C.

Key value for chemical safety assessment

Relative density at 20C:
1.407
