Figure 15. Densimeter Results Using the Four Fluids
The standard deviation for four fluids (Figure16) is 0.053 kg/m3 or 0.0053%. This is considered a good result when one takes into account that this value is only about twice as large as the claimed uncertainties for the Standard Reference Materials (0.025 kg/m3 for Toluene and 0.035 kg/m3 for Isooctane).
