Remarks on result:
other: Mean value of two assays (assay No.1: 5.730, assay No.2: 5.681)

Two independent measurements at 21.0°C (assay No. 1) and 21.2°C (assay No. 2) were done. Runs 1, 2, 3 and 4 of assay No. 1 were not taken into account because they did not comply with the quality criterion, also runs 1, 2 and 3 of assay No. 2 were not taken into account because they did not comply with the quality criterion.

The two assays resulted in relative densities of 5.730 ± 0.005 and 5.681 ± 0.005, respectively. The mean relative density was thus 5.706 ± 0.027 at 21.1°C.

Reference volume (VA) was 79.444 cm³.

Volume of sample cell holder (VC) was 27.678 cm³.

Test item sample weight was 8.4001 g and 8.1090 g in assay No. 1 and 2, respectively.

The measurements are described in the table in the next section.

Conclusions:
Based on the tests performed, the relative density of the test item was 5.706 ± 0.027 at 21.1°C.

Description of key information

Based on the guideline study (Klimisch 1, Demangel, 2017) the mean relative density of the test item is 5.706 ± 0.027 at 21.1°C.

Key value for chemical safety assessment

Relative density at 20C:
