This standard deals with hydraulic performance tests for acceptance of rotodynamic pumps (centrifugal, mixed flow and axial pumps, in the following simply designated as "pumps"). It may be applied to pumps of any size and to any pumped liquids behaving as clean cold water such as defined in clause 5.4.5.1. It is neither concerned with the structural details of the pump nor with the mechanical properties of their components. As mentioned above this standard 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. Applies either to a pump itself without any fittings or to a combination of a pump associated with all or part of its upstream and/or downstream fittings.
