Link to relevant study record(s)
- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2 October 1991 - 16 January 1992
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: Study conducted to GLP in compliance with agreed protocols, with no or minor deviations from standard test guidelines and/or minor methodological deficiencies, which do not affect the quality of the relevant results.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 109 (Density of Liquids and Solids)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.3 (Relative Density)
- Deviations:
- no
- GLP compliance:
- yes
- Type of method:
- pycnometer method
- Type:
- relative density
- Density:
- 5.408
- Temp.:
- 20 °C
- Conclusions:
- The relative density of the test material was found to be 5.408.
- Executive summary:
The relative density of the substance was determined in accordance with the standardised guidelines OECD 109 and EU Method A.3.
The density of the test material was determined relative to bi-distilled water using a pycnometer at 20 °C (293.15 K) and bi-distilled water was also employed as the displacing vehicle.
The relative density was found to be 5.408.

Description of key information
The relative density was determined to be 5.408.
Key value for chemical safety assessment
- Relative density at 20C:
- 5.408
Additional information
The relative density of the test material was determined in the key study in accordance with GLP and the standardised guidelines OECD 109 and EU Method A.3.
The density of the test material was determined relative to bi-distilled water using a pycnometer at 20 °C (293.15 K) and bi-distilled water was also employed as the displacing vehicle.
The relative density was found to be 5.408.
Supporting information is available in the form of a second study in which the relative density of the test material was investigated in accordance with GLP using a method designed to comply with the standardised guideline EU Method A.3.
The density was determined relative to water using a pycnometer with an immersion liquid. The test was carried out at 20.5 °C using hexane as the immersion liquid.
The relative density of the test material was determined to be 3.8777 at 20.5 °C.
