- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 15 November 2018
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 109 (Density of Liquids and Solids)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.3 (Relative Density)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EPA OPPTS 830.7300 (Density / Relative Density / Bulk Density)
- Deviations:
- no

- Key result
- Type:
- relative density
- Density:
- 0.94 other: dimensionless
- Temp.:
- 20 °C
- Conclusions:
- The density of the test item was determined to be 0.9399 at 20 °C.
- Executive summary:
A study was conducted according to OECD TG 109, Regulation (EC) No 440/2008 method A.3 and OPPTS 830.7300 to determine the relative density of the test item. The density was determined in six independent determinations. Using the pycnometer method the density was determined to be 0.9399 ± 0.01301 g/mL at 20 °C and the relative density 0.9399 with respect to water at 4 °C respectively. The standard deviation reflects the distinguished correlation of the individual determinations.
