Conclusions:
The density of the test item LUMULSE GMT-K was calculated as 0.9501± 0.0000 g/cm3 at 20.0 ±0.2°C was measured. This value is the mean of two independent determinations ± the standard deviation. Standard deviation shows perfect correlation of the two determinations.
Therefore, the study is considered valid.
Executive summary:

Determination of the Density of LUMULSE GMT-K according to OECD 109 resp. EU A.3

 

Findings and Results:

Using the pycnometer method, a density of 0.9501 ± 0.0000 g/cm3 at 20 ± 0.2 °C was measured. This value is the mean of two independent determinations ± the standard deviation. Standard deviation shows perfect correlation of the two determinations.

Description of key information

A density of 0.9501 ± 0.0000 g/cm3 at 20 ± 0.2 °C was measured.

Key value for chemical safety assessment
