Key result
Type:
relative density
Density:
ca. 2.073
Temp.:
19.1 °C
Remarks on result:
other: Mean value of two assays (assay No.1: 2.074 ± 0.001, assay No.2: 2.072 ± 0.002).

Two independent measurements were performed at 19.1°C.

The two assays resulted in relative densities of 2.074 ± 0.001 and 2.072 ± 0.002, respectively. The mean relative density was thus 2.073 ± 0.002 at 19.1°C.

Reference volume (Va) was 79.444 cm³.

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

Test item sample weight was 5.9608 g and 6.3448 g in assay No. 1 and 2, respectively.

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

Conclusions:
The relative density of yttrium trichloride hexahydrate was determined according to the EU A.3 method and OECD test guideline 109 in compliance with GLP using a gas comparison pycnometer. The relative density of the test item was determined to be 2.073 ± 0.002 at 19.1°C.

Description of key information

A guideline study (Demangel, 2017; Klimisch 1) to establish the relative density of the test item (yttrium trichloride hexahydrate) was performed according to the EU A.3 method and OECD test guideline 109 in compliance with GLP using a gas comparison pycnometer. The relative density of the test item was determined to be 2.073 ± 0.002 at 19.1°C. Results of this study are reliable without restrictions.
