Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Link to relevant study record(s)
- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 27 August 2002
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.3 (Relative Density)
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 109 (Density of Liquids and Solids)
- GLP compliance:
- yes (incl. QA statement)
- Other quality assurance:
- other: In-house quality assurance: study was periodically inspected and properly signed records of i nspections were submitted to testing facility
- Type of method:
- pycnometer method
- Dynamic viscosity of test material:
- No information on the dynamic viscosity of the test material is available. However, due to the high water content, the viscosity of the test material will be within the applicability domain of the method (i.e. < 500 Pa s).
- Key result
- Type:
- relative density
- Density:
- 1.071 other: (corresponds to D4(20))
- Temp.:
- 20 °C
- Conclusions:
- The relative density of the test item is 1.071 (corresponds to D4(20)).
- Executive summary:
The relative density of the test item was determined by the pycnometer meter in a GLP study according to EU test method A.3 and OECD testing guideline 109. The relative density of the test item is 1.071 (corresponds to D4(20)).

Density of water at 4 °C: 999.972 kg/m3
Formulas:
m (S) = m (P+S) - m (P)
V (S) = V (pycnometer)
Density (S) [kg/m3] = (m (S) [g] / V (S) [cm3]) 1000
Relative density = Density (S) [kg/m3] / 999.972 [kg/m3] (Density of water at 4 °C)
Description of key information
The relative density of the test item is 1.071 (corresponds to D4(20)).
Key value for chemical safety assessment
- Relative density at 20C:
- 1.071
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
