Link to relevant study record(s)
- Endpoint:
- density, other
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2018
- 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:
- An automatic gas pycnometer was used to determine the density of the substance, which was tested 1. 'as received' and 2. after drying at 200°C for 16 h under vacuum. Drying yielded a 1.7 wt-% loss.
Each sample was objectd to 10 analyses/test cycles. - GLP compliance:
- no
- Type of method:
- air comparison pycnometer (for solids)
- Specific details on test material used for the study:
- TREATMENT OF TEST MATERIAL PRIOR TO TESTING
A portion of the substance was dried at 200°C for 16 h under vacuum prior to the density investigations.
Besides the dried sample, a sample of the substance 'as received' was tested. - Dynamic viscosity of test material:
- not applicable (substance is a solid)
- Key result
- Type:
- density
- Density:
- 3.035 g/cm³
- Temp.:
- 25 °C
- Remarks on result:
- other: dried sample
- Remarks:
- average of a 10 dependent analyses
- Type:
- density
- Density:
- 3.003 g/cm³
- Temp.:
- 25 °C
- Remarks on result:
- other: sample tested as received
- Remarks:
- average of a 10 dependent analyses
- Conclusions:
- The density of the substance was determined to be 3.035 g/cm3 (at 25°C).
- Executive summary:
The density of the (dried) solid substance was determined to be 3.035 g/cm3 (at 25°C using a gas comparison pycnometer).
Reference
The systematic error is estimated at ≤ 1% relatively.
Since the systematic error is estimated at < 1% relatively, the maximum absolute error obtained over these samples is approx. 0.03 g cm-3.
Description of key information
The density of the substance was determined to be 3.035 g/cm3 (at 25°C).
Key value for chemical safety assessment
Additional information
Determined in a study comparable to a guideline study using an automatic gas pycnometer and dried sample.
