Results of duplicate determinations of relative density are shown in the following table;

Measurement  Determination 1  Determination 2 
Mass of Pycnometer(g)  21.2263  21.2905 
Mass of Pycnometer and distilled H2O at 20.0 deg C  46.1528  46.619 
Mass of Pycnomter and test material at 20.0 deg C  45.5014  45.9309 
Density of water at 20.0 deg C (kg/m3)  998.20  998.20 
Density (kg/m3)  972.12  971.07 
Relative density  0.972  0.971 

mean relative density: 0.972 and temperature: 20.0 +/- 0.5 deg C

Conclusions:
The relative density of the test material has been determined to be 0.972 at 20.0 ± °C
Executive summary:

The relative density for SiMAA2 was determined using the pycnometer method, Method A3 of Commission Directive 92/69/EEC (which constitutes Annex V of Council Directive 67/548/EEC).

The relative density of the test material has been determined to be 0.972 at 20.0 ± °C.
