Link to relevant study record(s)
- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 1995-04-24 to 1995-04-25
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- The study was conducted according to an internationally recognised method, and under GLP. No deviation affected the quality of the study. Purity is specified in the report, and isomers composition is available from the notifier. Therefore full validation applies.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.3 (Relative Density)
- Version / remarks:
- Commission Directive 92/69/EEC
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- Inspected on 31 January 1994. Signed on 16 March 1994
- Type of method:
- pycnometer method
- Dynamic viscosity of test material:
- no data
- Type:
- density
- Density:
- 927.26 kg/m³
- Temp.:
- 20 °C
- Key result
- Type:
- relative density
- Density:
- 0.927 other: relative density has no dimension
- Temp.:
- 20 °C
- Conclusions:
- The substance is less dense than water.
- Executive summary:
The density of the test substance was measured under GLP according EU A3 guideline, pycnometer method.
Two determinations were performed; results were consistent, so the average value was retained. The final density was converted to relative density vs density of water at 4°C.
The relative density D20/4 of test substance has been determined to be 0.927.
Reference
| determination | ||
| 1 | 2 | |
| a = mass of pycnometer (g) | 29.8927 | 26.1825 |
| b = mass of pycnometer and distilled water at 20°C (g) | 79.7913 | 75.9885 |
| c = mass of pycnometer and test material at 20°C (g) | 76.2496 | 72.4438 |
| d = density of water at 20.0°C (kg/m3) | 998.20 | |
| Density of test material (kg/m3) | 927.35 | 927.16 |
Mean density of test material = 927.26 kg/m3
Density of water at 4.0°C = 1000 kg/m3
Relative density of test material (D20/4) = 927.26 / 1000 = 0.92726
Description of key information
The substance is less dense than water.
Key value for chemical safety assessment
- Relative density at 20C:
- 0.927
Additional information
A fully reliable experimental study, conducted according to a recognized EC method and under GLP, is available. Therefore, it is considered as a key study. The result is retained as key data.
