Conclusion:The relative density of the test item has been determined to be 2.056 at 23.0 ± 0.5°C.
Executive summary: The relative density of the test material has been determined to be 2.056 at 23.0 ± 0.5°C, using the specimens’ non-solvent cyclohexane and a glass pycnometer, designed to be compatible with Method A3 Relative Density of Commission Regulation (EC) No 440/2008 of 30 May 2008.
