Conclusions:
The mean result for Relative density for Thio-Acid is (D 20 4) 1.352
Sample density 1352 kg.m-3 @ 20°C
Executive summary:

The test is conducted to determine the relative density of a solid or liquid substance. For solids or liquids, pycnometers of various shapes and with known volumes may be employed. The density is calculated from the difference in weight between the full and empty pycnometer and its known volume. The tests are run at a constant temperature, preferably 20°C, and at least two measurements are generally performed.

The test is conducted in accordance with the procedure described in EU Regulation (EC) 440/2008, Annex Part A test A3.

The mean result for Relative density for Thio-Acid at 20°C is 1352 kg/m-3.
