- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EPA OPPTS 830.7300 (Density / Relative Density / Bulk Density)
- Version / remarks:
- United States Environmental Protection Agency (EPA), 2002
- Deviations:
- no

- Type of method:
- air comparison pycnometer (for solids)
- Type:
- relative density
- Density:
- 2.23 other: no unit for relative denisty
- Temp.:
- 20 °C
- Remarks on result:
- other: to water at 4 °C
- Conclusions:
- The measured density of sample was 2228.7 ± 19.0 kg/m³ at 20 °C. The relative density of the sample at 20 °C to water at 4 °C is 2.23.
- Executive summary:
The relative density test was carried out according to OECD Guideline No 109, EU Method A.3 and OPPTS 830.7300 under GLP compliance.
The test was performed at a temperature of 20 ± 0.5 °C. A known weight of the test item was placed in the sample cell and its volume determined by the density tester. The density of the test item was calculated from its weight and of the defined volume.
The measured density of the sample was 2228.7 ± 19.0 kg/m³ at 20 °C. The relative density of the sample at 20 °C to water at 4 °C is 2.23.

Description of key information
The relative density test was carried out according to OECD Guideline No 109, EU Method A.3 and OPPTS 830.7300 under GLP compliance.
The test was performed at a temperature of 20 ± 0.5 °C. A known weight of the test item was placed in the sample cell and its volume determined by the density tester. The density of the test item was calculated from its weight and of the defined volume.
The measured density of the sample was 2228.7 ± 19.0 kg/m³ at 20 °C. The relative density of the sample at 20 °C to water at 4 °C is 2.23.
Key value for chemical safety assessment
- Relative density at 20C:
- 2.23
