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
Reference:
Composition 0
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.

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.

Description of key information

Under the conditions of the study the density of the test material was 7.84 g/cm³.

Key value for chemical safety assessment
