Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The relative density is the ratio between the mass of a volume of the sample at 20°C, and the mass of the same volume of water, determined at 4°C. The relative density has no dimension and is given by the formula
D= (m1/m2)*p
where:
m1 is the apparent mass, in grams, of sample required to fill the flask at 20°C
m2 is the apparent mass, in grams, of water required to fill the flask at 20°C
p is the density of water at 20°C = 0.9982g/mL
Description of key information
The relative density of the test material is given by: 0.001058 g/L at 20°C (EU Method A.3 (Relative Density)).
Key value for chemical safety assessment
- Relative density at 20C:
- 1.058
Additional information
The density is calculated from the difference in weight between the full and empty pycnometer and its known volume.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
