Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 07 March 2018
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Justification for type of information:
- The study was conducted according to an internationally recognised method, and under GLP. The test substance is adequately characterised. Therefore full validation applies.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 109 (Density of Liquids and Solids)
- Version / remarks:
- 2012
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.3 (Relative Density)
- Version / remarks:
- 2008
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- Inspected on 4,5 and 6 July 2016/ Signed on 10 January 2017
- Type of method:
- pycnometer method
- Key result
- Type:
- relative density
- Density:
- 0.946 other: unitless
- Temp.:
- 20 °C
- Key result
- Type:
- density
- Density:
- 945.8 kg/m³
- Temp.:
- 20 °C
- Conclusions:
- The density of the test item has been determined to be 945.8 kg/m3 at 20.0 +/- 0.1°C (mean of two determinations).
The relative density of the test item was determined to be D204 = 0.946. - Executive summary:
The study was performed in order to determine the density of test item according OECD 109, resp. EU A.3 guideline, using a pycnometer.

Description of key information
The density of the test item has been determined to be 945.8 kg/m3 at 20.0 +/- 0.1°C (mean of two determinations).
The relative density of the test item was determined to be D204 = 0.946.
Key value for chemical safety assessment
- Relative density at 20C:
- 0.946
Additional information
A fully reliable experimental study, conducted according to OECD 109/ EU A3 guideline is available.
It is considered as a key study, and the result is retained as key data.
