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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 446-560-3 | CAS number: -
Density
Administrative data
Link to relevant study record(s)
- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 6 Feb - 13 Mar 2002
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.3 (Relative Density)
- Version / remarks:
- Test method A.3 (section 1.4.4), ".determination of the relative density", described in the EG guideline
92/69. - Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- other: DIN 51757
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- oscillating densitimeter
- Remarks:
- An U-formed tube, which can be caused to vibrate, is filled with approx. 0.7 ml of the liquid sample. The change of the vibration frequence in consequence of the changed mass is used to determine the density of the sample considering calibration data.
- Key result
- Type:
- relative density
- Density:
- 1.569
- Temp.:
- 20 °C
- Conclusions:
- The relative density of the test item at 20°C is: 1.5690.
- Executive summary:
The relative density of the test item at 20°C is: 1.5690.
Reference
The key result is the mean of two measured values: 1.5690 and 1.5689.
Validity criteria for the measurement of the denisty:
| Target condition according to guideline: | Actual condition according to the study: | Validity criteria met: |
| The tests have to be run at 20 °C. | The tests were performed at 20°C. | Yes |
| At least two measurements have to be performed. | Two values were measured. | Yes |
The relative density, D204, of solids or liquids is the ratio between the mass of a volume of substance to be examined, determined at 20 °C, and the mass of the same volume of water, determined at 4 °C. The relative density, D204, shall be reported as defined, along with the physical state of the measured substance. | The values of the relative densities are stated without further detail to the method or calculation used. The phsyical state of the measured substance is not stated. | No. Nevertheless, although there are few details about the method stated in the study report, the relative density was determined according to guideline 92/69/EWG nad DIN 51757. Thus, the detailed specifications stated in these guidelines may be considered as being fulfilled. |
Description of key information
The relative density of the test item at 20 °C is: 1.5690.
Key value for chemical safety assessment
- Relative density at 20C:
- 1.569
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).
