The mean relative density was determined at 19.9°C as 1.5068 (individual values: 1.5071 g/cm3 and 1.5064 g/cm3).

Conclusions:
The relative density at 20 °C (compared to water at 4 °C) of the test item was found to be 1.5068.
Executive summary:

The relative density of the test item was determined according to Regulation (EC) No 440/2008 Part A. Method A.3 and OECD Test Guideline 109 using the air comparison pycnometer method. The relative density at 20 °C (compared to water at 4 °C) of the test item was found to be 1.5068. This value is the mean of two experiments with five replicates each.

Description of key information

The relative density at 20 °C (compared to water at 4 °C) of the test item was found to be 1.5068 (reference 4.4-1).

Key value for chemical safety assessment

Relative density at 20C:
1.507
