Executive summary:

The density for the test substance, TMAC T (purity not specified) was determined using pycnometer method according to Method NF T20 – 053 (determination of density of solids in powder and liquids). The determination was carried out with a pycnometer using the displacement method and hexadecane as solvent, in duplicate. Under the study conditions, the average density of the test substance was determined to be 0.94 g/cm3 at 20 ºC and the relative density was 940 (Borjesson, 2012).
