Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Density
Administrative data
Link to relevant study record(s)
- Endpoint:
- relative density
- Type of information:

- Adequacy of study:
- key study
- Study period:
- 22 Oct 2015 - 25 Feb 2016
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 109 (Density of Liquids and Solids)
- Deviations:
- no
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- EU Method A.3 (Relative Density)
- Deviations:
- not applicable
- GLP compliance:
- no
- Other quality assurance:
- ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories)
- Type of method:
- pycnometer method
- Specific details on test material used for the study:
- Purity not specified
- Key result
- Type:
- relative density
- Density:
- 1.228
- Temp.:
- 20 °C
- Remarks on result:
- other: mean value of 2 determinations
- Conclusions:
- The density of the substance at 20 ºC was 1.228 g/cm³ and the relative density was 1.228.
- Executive summary:
According to the OECD Guideline 109 (Density of Liquids and Solids) corresponding to A.3., Council Regulations EC No 440/2008 the solid sample was accurately weighed into a 20 mL pycnometer and by displacement of the solvent (n-heptan), its equivalent volume was determined. Finally, the density of the sample was calculated. The relative density at 20 ºC was 1.228 g/cm3 and the relative density was 1.228.
Reference
Literature data (CRC Handbook of Chemistry and Physics 75th Edition)
d (20, w) (density of water at 20 °C) = 0.9982 g/mL
d (4, w) (density of water at 4 °C) = 0.99997 g/mL
d (20, a) (density of air at 20 °C) = 0.0012 g/mL
Validity criteria for the measurement of the density:
| Target condition according to guideline: | Actual condition according to the study: | Validity criteria met: |
| The test is done at constant temperature, preferably at 20°C. | The pycnometer was thermostated at 20 °C in a water bath until the readings of the filling height remained constant. | Yes |
| Duplicate measurements are required. | The key value is the mean value of two measurements. | Yes |
Description of key information
