- Adequacy of study:
- key study
- Study period:
- 21-06-2013
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: Guideline study performed under GLP. All relevant validity criteria were met.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.3 (Relative Density)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 109 (Density of Liquids and Solids)
- Deviations:
- no

- Density:
- 1.29 g/cm³
- Temp.:
- 25 °C
- Remarks on result:
- other: Applicant converted units to 1.29 g/cm3 at 25.0 ± 0.5°C
- Conclusions:
- The density of the test item has been determined to be 1.29 g/cm^3 (or 1290 kg/m^3) at 25.0 ± 0.5°C.
- Executive summary:
The density was determined using the gas pycnometer method within EU Method A.3 and OECD TG 109 under GLP. All measurements were performed in triplicate and two determinations were performed to ensure a reproducibility of less than ± 20 kg/m^3 was obtained. The mean density of the test item has been determined to be 1.29 g/cm^3 (or 1290 kg/m^3) at 25.0 ± 0.5°C.
