Density
Administrative data
Link to relevant study record(s)
- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- April 2005
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: Study conducted to GLP and in compliance with agreed protocols, with no or minor deviations from standard test guidelines and/or minor methodological deficiencies, which do not effect the quality of the relevant results.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.3 (Relative Density)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- pycnometer method
- Type:
- relative density
- Density:
- 0.7
- Temp.:
- 20 °C
- Conclusions:
- relative density: 0.701 at 20.0 ± 0.5°C
- Executive summary:
The relative density was determined using the pycnometer method, EU Method A.3. The relative density of the test substance at 20.0 ± 0.5°C was 0.701 (arithmetic mean of two determinations).
Reference
Calculation
The relative density was calculated using Equation 1 and Equation 2:
Equation 1: Density [kg/m³] = d(c - a)/(b-a)
where:
a = mass of pycnometer (g)
b = mass of pycnometer filled with water (g)
c = mass of pycnometer filled with test material (g)
d = density of water at test temperature (kg/m³)
Equation 2:Relative density =ρ/ρ(H2O, 4°C)
where:
ρ= density of test material (kg/m³)
ρ(H2O, 4°C) = density of water at 4°C (999.97 kg/m³)
Results
The results of the duplicate determinations (at 20°C) are shown in the following table:
| Determination | ||||
| 1 | 2 | |||
| Mass of pycnometer (g) | 8.0557 | 7.9184 | ||
| Mass of pycnometer and distilled water at 20.2°C (g) | 17.6990 | 17.7586 | ||
| Mass of pycnometer and test material at 20.4°C (g) | 14.8256 | 14.8267 | ||
| Density of water at 20.2°C (kg/m³) | 998.16 | 998.16 | ||
| Density (kg/m³) | 700.74 | 700.76 | ||
| Relative density | 0.701 | 0.701 | ||
Mean relative density: 0.701
Temperature: 20.0 ± 0.5°C
Description of key information
relative density of the test material: 0.701 (at 20.0 ± 0.5°C)
Key value for chemical safety assessment
- Relative density at 20C:
- 0.701
Additional information
The relative density was determined using the pycnometer method, EU Method A.3. The relative density of the test substance at 20.0 ± 0.5°C was 0.701 (arithmetic mean of two determinations).
