Resumen:
The document deals with hydraulic performance tests for acceptance of rotodynamic pumps (centrifugal, mixed flow and axial pumps). It may be applied to pumps of any size and to any pumped liquids behaving as clean cold water. It is neither concerned with the structural details of the pump nor with the mechanical properties of their commponents. The document contains two grades of accuracy of measurement: Grade 1 for higher accuracy and grade 2 for lower accuracy. These grades include different values for tolerance factors, for allowable fluctuations and uncertainties of measurement.
