The results of the two measurements of the density for the test substance were: 1.3874 g/cm3 and 1.3854 g/cm3 .The mean relative density of the test item was determined to be 1.3864 at 20.3 °C (two samples).

Conclusions:
The mean relative density of the test item was determined to be 1.3864 at 20.3 °C.
Executive summary:

A study was conducted according to Regulation (EU) No. 440/2008 method A.3 and OECD Guideline No. 109(2012) to determine the relative density of the test item. The density was determined in two assays. Using the pycnometer method the density of the test item at 20.3 °C was determined to be 1.3874 g/cm3 and 1.3854 g/cm3, respectively. The mean relative density of the test item was determined to be 1.3864 at 20.3 °C.


Description of key information

The mean relative density of the test item was determined to be 1.3864 at 20.3 °C (reference 4.4-1).

Key value for chemical safety assessment

Relative density at 20C:
1.386
