Applicant's summary and conclusion
- Conclusions:
- The relative density of the test material has been determined to be 1.75 at 21.2 ± 0.5°C.
- Executive summary:
In a determination of general physico-chemical properties study (Harlan project number: 0959/0224) the test material is shown to have a relative density of 1.75 at 21.2 ± 0.5°C. The determination was carried out using a gas comparison pycnometer (Quantachrome MVP-2), Method A3 Relative Density of Commission Regulation (EC) No 440/2008 of 30 May 2008.
