Administrative data
Link to relevant study record(s)
- Endpoint:
- density, other
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- Not stated
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study with acceptable restrictions
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- The specific density was measured with a helium pycnometer. An amount of dry test material was weighed into the beaker and then the sample cell was purged with helium for at least five minutes. The free space of the sample cell was filled with helium and referred to the calibrated volume.
- GLP compliance:
- not specified
- Type of method:
- pycnometer method
- Key result
- Type:
- density
- Density:
- 7.84 g/cm³
- Remarks on result:
- other: no information on temperature provided
- Conclusions:
- Under the conditions of the study the density of the test material was 7.84 g/cm³.
- Executive summary:
The specific density was measured with a helium pycnometer. An amount of dry test material was weighed into the beaker and then the sample cell was purged with helium for at least five minutes. The free space of the sample cell was filled with helium and referred to the calibrated volume. When the last three runs achieved a deviation of ± 0.02 %, the measurement was successfully complete.
Under the conditions of the study the density of the test material was determined to be 7.84 g/cm³.
