Over deze norm
This International Standard specifies hydraulic performance tests for customers acceptance of rotodynamic pumps (centrifugal, mixed flow and axial pumps, in the following simply designated as „pumps"). This International Standard is intended to be used for pump acceptance testing at pump test facilities, such as manufacturers pump test facilities or laboratories. It may be applied to pumps of any size and to any pumped liquids that behave as clean cold water. This International Standard contains 3 levels of acceptance; - Grades 1B, 1E and 1U with tighter tolerance band - Grades 2B, 2U with broader tolerance band and - Grade 3B with even broader tolerance band. This International Standard 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.
