- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- Testing was conducted between 15 June 2011 and 20 December 2011.
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- Study conducted in compliance with agreed protocols, with no or minor deviations from standard test guidelines and/or minor methodological deficiencies, which do not affect the quality of the relevant results. The study report was conclusive, done to a valid guideline and the study was conducted under GLP conditions.
- Qualifier:

- Key result
- Type:
- relative density
- Density:
- 1.61 other: Unitless
- Temp.:
- 21 °C
- Conclusions:
- The relative density of the test item has been determined to be 1.61 at 21.0 ± 0.5°C.
- Executive summary:
The determination was carried out using a gas comparison pycnometer, designed to be compatible with Method A3 Relative Density of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 109 of the OECD Guidelines for Testing of Chemicals, 27 July 1995. The relative density of the test item has been determined to be 1.61 at 21.0 ± 0.5°C.
