The relative density of the test item was determined to be 1.6653 ± 0.03065 (with 95 % confidence interval) at 20 °C.

 

Conclusions:
The relative density of the test item was determined to be 1.6653 ± 0.03065 (with 95 % confidence interval) at 20 °C.

Description of key information

The relative density of the test item was determined to be 1.6653 ± 0.03065 (with 95 % confidence interval) at 20 °C.

Key value for chemical safety assessment

Additional information

A study was conducted according to OECD TG 10, Regulation (EC) No 440/2008 method A.3 and OPPTS 830.7300 to determine the relative density the test item (reference 4.4-1). The density was determined in five independent determinations. Using the pycnometer method the density was determined to be 1.6653 ± 0.03065 g/cm3 at 20 ± 0.5 °C and the relative density 1.6653 with respect to water at 4 °C respectively.
