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
- Reference substance name:
- Reaction mass of calcium carbonate and calcium sulfate and magnesium hydroxide
- Molecular formula:
- not applicable - multi-constituent substance
- 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
