Table 6 Uncertainty in volume made up to 50 mL [V TEST ]
Uncertainty components | Distribution | Calibration uncertainty | Standard uncertainty ± μ(x) |
|---|---|---|---|
Calibration uncertainty of flask as per certificate; k = 2 | Normal | 50 ± 0.02 mL | 0.02/2 = 0.01 |
Effect of temperature variation on 50 mL volumetric flask at 95% confidence level | Rectangular | 50 × *3 × 2.1 × 10-4 = 0.032 | 0.032/√3 = 0.018 |
