Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

relative density
Type of information:
experimental study
Adequacy of study:
key study
Study period:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
according to guideline
OECD Guideline 109 (Density of Liquids and Solids)
Principles of method if other than guideline:
The test is conducted in accordance with the procedure described in EU Regulation (EC) 440/2008, Annex Part A test A.3 and OECD Test Guideline 109.

The relative density 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 has no dimension.

The density, ρ, of a substance is the quotient of the mass, m, and its volume, v. The density, ρ, is given, in SI units, in kg/m3.

For solids or liquids, pycnometers of various shapes and with known volumes may be employed. The density is calculated from the difference in weight between the full and empty pycnometer and its known volume. The tests are run at a constant temperature, preferably 20°C, and at least two measurements are generally performed.
GLP compliance:
yes (incl. QA statement)
Type of method:
pycnometer method
