Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Materials and methods

Test guideline
Qualifier:
equivalent or similar to guideline
Guideline:
EU Method A.3 (Relative Density)
Principles of method if other than guideline:
The relative density has been measured at 20 ± 1 °C using a gas pycnometer. With this method, the volume of the test substance is measured in helium in a calibrated cell. Knowing the mass of sample introduced in the cylinder, the density and relative density can be calculated. Before the measurements, the equipment is calibrated with reference metallic balls.
GLP compliance:
no
Type of method:
pycnometer method

Test material

IUPAC Name:
Reaction mass of calcium carbonate and calcium sulfate and magnesium hydroxide
Details on test material:
Two samples of the test substance were tested: SOLVCAT and Granelli CRG
Both were sampled on 2 September 2009
