Note 1: In case of Pressure generated from a pneumatic dead weight tester, Fluid head correction factor (ρf.g.∆h) may be considered negligible and pressure distortion correction (1+ λ∗ p) may be considered negligible if not reported in the certificate

Note 2: In case of absolute pressure measurements, the atmospheric pressure should be added to the generated pressure. The uncertainty component of atmospheric pressure measuring device should also be included while estimating the measurement uncertainty of calibration.
