This International Standard specifies hydraulic performance tests for acceptance of rotodynamic pumps (centrifugal,
mixed flow and axial pumps, hereinafter simply designated as pumps). It is applicable to pumps of any size and to
any pumped liquids behaving as clean cold water (such as defined in 5.4.5.2). It is neither concerned with the
structural details of the pump nor with the mechanical properties of their components.
This International 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.
For pumps produced in series with selection made from typical performance curves and for pumps a with power
input of less than 10 kW, see annex A for higher tolerance factors.
This International Standard is applicable both to a pump itself without any fittings and to a combination of a pump
associated with all or part of its upstream and/or downstream fittings.
Die Prüfungen zur Feststellung der Leistungen von Kreiselpumpen werden festgelegt, wobei zwei Meßgenauigkeitsklassen beschrieben sind. Die Prüfanordnungen, die Prüfungsdurchführung und die Auswertung der Prüfergebnisse sind detailliert dargestellt.
