Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- 3 May 1994 to 15 Jul 1994
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.3 (Relative Density)
- GLP compliance:
- yes
- Type of method:
- pycnometer method
- Key result
- Type:
- relative density
- Density:
- 1.735 other: dimensionless
- Temp.:
- 20 °C
- Type:
- density
- Density:
- 2 g/cm³
- Temp.:
- 20 °C
- Conclusions:
- The absolute density was 2.0 g/cm3 at 20 ºC, corresponding to a relative density of 1.735.
- Executive summary:
The study was performed according to the EC A.3 and in compliance with GLP for determing the relative density of the test substance. The absolute density of the test substance has been determined to be 2.0 g/cm3 at 20 ºC from the two determinations performed, corresponding to a relative density of 1.735.

RESULTS
Sample #1 aliquot weight = 10.5147 g
Sample #1 aliquot volume = 5.2117 cm3
Sample #1 aliquot density = 10.5147 g / 5.2117 cm3 = 2.0175 g/cm3
Sample #2 aliquot weight = 12.1193 g
Sample #2 aliquot volume = 6.0943 cm3
Sample #2 aliquot density = 12.1193 g / 6.0943 cm3 = 1.9886 g/cm3
The mean absolute density was 2.00 g/cm3. Note: The purpose of following this procedure was to fulfill the requirements of the EEC for the test substance as detailed in EEC Method A3. The test substance was analyzed by helium pycnometry. The helium pycnometric method is included in EEC Method A3. This method measures absolute density of a solid sub-stance and not relative density. Since EEC Method A3 employs the title "Relative Density", so it is used in this report; however, the more correct term "absolute density" is reported above.
Description of key information
Relative density was determined to be 1.735 (corresponding to an absolute density of 2.0 g/cm3), pycnometer method, EU Method A.3, Gallacher 1994.
Key value for chemical safety assessment
- Relative density at 20C:
- 1.735
