ABSTRACT This International Standard specifies hydraulic performance te sts for acceptance of rotodynamic pumps (centrifugal, mixed fl ow and axial pumps, in the following simply designated as "pum ps"). This International Standard is intended to be used for p ump acceptance testing at pump test facilities, such as manufa cturers pump test facilities or laboratories. It may be applie d to pumps of any size and to any pumped liquids that behave a s clean cold water. This International Standard contains 3 classes of accuracy of measurement: class 1 x for higher accuracy and class 2 and 3 for lower accuracy. These classes include d ifferent values for tolerance factors, for allowable fluctuati ons and uncertainties of measurement. This International Stand ard applies either to a pump itself without any fittings or to a combination of a pump associated with all or part of its up stream and/or downstream fittings.
