Reference
Endpoint:
relative density
Type of information:
experimental study
Adequacy of study:
key study
Study period:
24 April 2018
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
OECD Guideline 109 (Density of Liquids and Solids)
Version / remarks:
2 October 2012
Deviations:
no
GLP compliance:
yes (incl. QA statement)
Type of method:
pycnometer method
Specific details on test material used for the study:
- Storage conditions: The test material was stored in a dark storage place at room temperature.
- Test material identification and stability under storage: The infrared (IR) spectrum of the test material measured at the test facility was confirmed to be identical to that provided by the sponsor. In addition, the IR spectrum of the test material after the completion of the experiment was the same as that before the start of the experiment, and it indicated that the test material was stable under storage conditions.

Conclusions:
Under the conditions of this study the density of the test material was 1.343 g/cm^3 at 20 °C. The specific gravity was 1.343.
Executive summary:

The relative density of the test material was investigated in accordance with the standardised guideline OECD 109 and under GLP conditions, using the pycnometer method.

The density of the test material was calculated from the difference in weight between the full and empty pycnometer. The test was run at a temperature of 20 °C, and two repetitions were performed.

Under the conditions of this study the density of the test material was 1.343 g/cm^3 at 20 °C. The specific gravity was 1.343.

Additional information

The relative density of the test material was investigated in accordance with the standardised guideline OECD 109 and under GLP conditions, using the pycnometer method. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).

The density of the test material was calculated from the difference in weight between the full and empty pycnometer. The test was run at a temperature of 20 °C, and two repetitions were performed.

Under the conditions of this study the density of the test material was 1.343 g/cm^3 at 20 °C. The specific gravity was 1.343.
