Mean density p for the two test series: 1.20 cm3

Relative density (compared to water at 4 °C): 1.20.

Conclusions:
The relative density of the test item at ambient temperature (compared to water at 4°C) was determined to be 1.20 (20.0°C).
Executive summary:

A study was conducted according to OECD TG 109, Regulation (EC) No 440/2008 method A.3 to determine the relative density of the test item. The density was determined in six independent determinations. Using the pycnometer method the density was determined to be 1.20 g/cm3 at 20.0 °C and the relative density 1.20 with respect to water at 4 °C respectively.

Description of key information

The relative density of the test item at ambient temperature (compared to water at 4°C) was determined to be 1.20 (20.0°C). (reference 4.4 -1).

Key value for chemical safety assessment

Relative density at 20C:
1.2
