Conclusions:
The relative density of MEA-LAS was 1.001 g/mL, corresponding to 1001 kg/m3 at 20°C, measured by the pycnometer method.
Executive summary:

The relative density of MEA-LAS was determined following guideline EU Method A.3 (Relative Density) with pycnometer.

The density was calculated from the difference in weight between the full and empty pycnometer and its known volume. The tests were run at a constant temperature, preferably 20°C, and at least two measurements were performed.

The relative density of MEA-LAS was 1.001 g/mL corresponding to 1001 kg/m3 at 20°C, measured by pycnometer method.

This density test is classified as acceptable, and satisfies the guideline requirements of the EU Method A.3.
