Findings

Relative density

EEC A.3

(CIPAC MT 3.2.1)

Absolute – 1.411 g/ml

Relative – 1.411

Conclusions:
The relative density of the test item is 1.411.
Executive summary:

The density determination of the test item, using the Gay-Lussac pycnometer in accordance with EU Method A3 (CIPAC MT 3.2.1) was based in measuring the mass of the substance occupying a unit volume at 20˚C (GLP study). The average measured absolute density at 20°C was 1.411 g/ml, and the average calculated relative density at 20°C temperature was 1.411.

Description of key information

Key study. Method according to EU A.3/CIPAC MT 3.2.1, GLP study. The relative density of the test item at 20ºC is 1.411.

Key value for chemical safety assessment

Relative density at 20C:
1.411
