The density of the test item was calculated as 1.0023 ± 0.0001 g/cm3at 20.0 ± 0.2°C.

Conclusions:
The density of the test item was calculated as 1.0023 ± 0.0001 g/cm3 at 20.0 ± 0.2°C.
Executive summary:

The study was performed in order to determine the density of the test substance according to OECD 109 and EU Method A3 guidelines, using the pycnometer method.

The density of the test item was calculated as 1.0023 ± 0.0001 g/cm3at 20.0 ± 0.2°C.

This value is the mean of two independent determinations ± the standard deviation. Standard deviation shows very good correlation of the two determinations.

Description of key information

The density of the test item was calculated as 1.0023 ± 0.0001 g/cm3 at 20.0 ± 0.2°C.

This is a mean of two independent determinations.

Key value for chemical safety assessment

Relative density at 20C:
1.002

Additional information

A fully reliable experimental study, conducted according to OECD 109/ EU A3 guideline is available.

It is considered as a key study, and the result is retained as key data.
