- Conclusions:
- The average calculated relative density at 20ºC temperature of the test item is 1.663.
- Executive summary:
The relative density of the test item has been determined using the Gay-Lussac pycnometer according to EU method A.3 and CIPAC MT 3.2.1, following GLP. The average measured absolute density at 20ºC temperature was 1.663 g/ml. The average calculated relative density at 20ºC temperature of the test item is 1.663.
