Density
Administrative data
Link to relevant study record(s)
- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 29 October 1998
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.3 (Relative Density)
- Deviations:
- no
- GLP compliance:
- yes
- Type of method:
- air comparison pycnometer (for solids)
- Type:
- relative density
- Density:
- 1.29
- Temp.:
- 24.3 °C
- Conclusions:
- The relative density (compared to water at 4 °C) is DR4= 1.29
- Executive summary:
The purpose of the test was the determination of the relative density according to Guideline 92/69/EEC of 31 July 1992, Annex. Part A: Methods for the determination of physico-chemical properties. A.3. Relative Density. The study was conducted in compliance with the Principles of Good Laboratory Practice (GLP).
The density of a solid in any form can be measured at room temperature with the gas comparison pycnometer. The volume of a substance is measured in air or in an inert gas in a cylinder of variable calibrated volume. For the calculation of density one mass measurement is taken after concluding the volume measurement. Instrument: gas comparison pycnometer, model 930 (Beckmann).
The relative density (compared to water at 4 °C) is DR4= 1.29
