- Executive summary:
A study was conducted to determine the relative density of the test substance, C16 TMA-MS (93.44% active) according to OECD Guideline 109 and EU Method A.3 (pycnometer method). Pycnometers were used to estimate the relative density. The empty and dry pycnometer was weighed, filled with the test substance and incubated at 20°C for 20 min. The pycnometer was then stoppered, wiped and weighed. Thereafter, it was filled with demineralized water and incubated at 20°C. Afterwards, the pycnometer was topped up to the mark, wiped and weighed. The relative density (D20/4) was measured as the ratio between the mass of a volume of test substance and the mass of the same volume of water at 4°C. Under the study conditions, the relative density of the test substance was determined to be 1.0173 at 20°C (Henkel, 2016).
