- Conclusions:
- The relative densityof the test item is 2.54 g/cm3 (at 20.2°C)
- Executive summary:
The density of test item was determined acccording to OECD guideline 109 / EU method A.3 using the Gas comparison pycnometry method.
Two test item samples were tested. Three measures were performed with each sample. The result is a mean value.
Relative density was measured as 2,54 g/cm3 at 20.2°C. This data is considered as a key data.

Description of key information
The relative density of the test item is 2.54 g/cm3 (at 20.2°C).
The test item is denser than water.
Key value for chemical safety assessment
- Relative density at 20C:
- 2.54
Additional information
A fully reliable experimental study, conducted according to a recognized OECD/EC method and under GLP, is available. It is considered as a key study.
This data is supported by an handboock data.
