* Due to a run precision function of the instrument, the analysis stopped when 5 results are gained that have a variation of less than 0.05% of the cell volume, Run 1 was not used to calculate the mean value as it was ouside this acceptance criteria.

Conclusions:
Using the AccuPyc 1330TC Pycnometer, with a water bath temperature measured at 20degC +/- 0.5degC, Dechlorane plus 25 was found to have a mean relative density of 1.71 g/cm3.
Executive summary:

Experimental determination of the density of Dechlorane plus 25 was performed using an AccuPyc 1330TC Pycnometer in accordance with EU A3 Air Comparison Pycnometer Method using Helium. 2 tests of 5 runs each were performed using 2.2547 g and 2.5305 g of the sample. Test 1 resulted in a relative density of 1.7079 g/cm3 and Test 2 resulted in a relative density of 1.7097 g/cm3. Dechlorane plus 25 was found to have a mean relative density of 1.71 g/cm3.
