Link to relevant study record(s)
- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 15 March 2017 - 07 November 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- Study was conducted in accordance with international guidelines and in accordance with GLP. All guideline validity criteria were met.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.3 (Relative Density)
- Version / remarks:
- Regulation (EC) 440/2008 of 30 May 2008
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 109 (Density of Liquids and Solids)
- Version / remarks:
- 02 October 2012 version
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- oscillating densitimeter
- Dynamic viscosity of test material:
- Viscosity is not a REACH data requirement for Registrations below Annex IX. In the absence of a prescribed data requirement, dynamic viscosity was assessed using expert judgement. The test item was deemed to have a dynamic viscosity less than 5 Pa s. The test item is not regarded to be sufficiently viscous to prevent the use of the oscillating densitometer method to determine the relative density of the test item.

- Conclusions:
- The relative density of the test item was determined to be 1.0436 at 20 ˚C.
- Executive summary:
EU Method A.3. – The relative density of the test item was determined utilising an oscillating densitometer. The procedure employed was designed to be compatible with Method A.3. Relative Density of Commission Regulation (EC) No 440/2008 of 30 May 2008.
Two determinations were carried out. An instrumentation check was performed using ultra-pure water. The measuring cell was cleaned put and dried. Approximately 1 cm3 of a visually bubble free, homogenous sample of test item was injected into the measuring cell. The density of the test item was determined. This determination was performed twice at 20.0 °C ± 0.2 °C to acquire an average value.
The mean relative density (D420) of the test item was determined to be 1.0436, based on the ratio of the measured density of the test item relative to the density of water at 4 °C i.e.;
D420 =rtest item/rwater
where:
rtest item= density of test item at 20.0 °C (g/cm3)
rwater= density of water at 4.0 °C (g/cm3)
