ASTM D1217 Standard Test Method for Density and Relative Density (Specific Gravity) of Liquids by Bingham Pycnometer
12. Report
12.1 In reporting density, give the test temperature and the units (for example, density, 20°C = x.xxxxx g/mL). In reporting relative density (specific gravity), give both the test temperature and the reference temperature, but no units (for example, relative density (specific gravity), 20/4°C = x.xxxxx). Carry all calculations to one digit beyond the last significant figure, but report the final result to the fifth decimal place (0.00001).
13. Precision and Bias
13.1 Precision - Results, using the 25-mL Bingham-type pycnometer, should not differ from the mean by more than the following amounts:
NOTE 7 - The precision for this method was not obtained in accordance with RR:D02-1007.
13.2 Bias - The difference of results from the established values when compared to pure reference materials is not expected to be more than more or less 0.00003 g/mL. Specific bias has not been established by cooperative testing.
