Key result
Type:
relative density
Density:
2.471
Temp.:
20.5 °C
Remarks on result:
other: Mean value of two assays (each in triplicate) (assay No. 1: 2.471, assay No. 2: 2.471).

Two independent measurements at 20.5°C were done (each in triplicate), each resulting in a mean relative density value of 2.471 +/- 0.002. The mean relative density of the test item was thus also 2.471 +/- 0.002.

Conclusions:
The relative density of dysprosium trinitrate (hexahydrated form) was determined to be 2.471 ± 0.002 at 20.5°C.
Executive summary:

The relative density of dysprosium trinitrate was determined according to EU A.3 method and OECD test guideline 109 in compliance with GLP using a gas comparison pycnometer. The relative density of dysprosium trinitrate was determined to be 2.471 ± 0.002 at 20.5°C.

Description of key information

The relative density of dysprosium trinitrate (hexahydrated form) was determined to be 2.471 ± 0.002 at 20.5°C.

Key value for chemical safety assessment

Relative density at 20C:
2.471

Additional information

An experimental study of reliability 1 according to Klimisch, performed in compliance with GLP and according to EU method A.3 and OECD Guideline 109 using gas comparison pycnometry, was selected as a key study.

The relative density was determined to be 2.471 +/- 0.002 at 20.5°C. Although the assay was not performed at strictly 20°C, the relatively small temperature difference is not considered to have influenced the density of the solid material to a significant extent.
