This International Standard specifies hydraulic performance tests for customers’ acceptance of rotodynamic pumps (centrifugal, mixed flow and axial pumps, hereinafter “pumps”).<\/p>\n
This International Standard is intended to be used for pump acceptance testing at pump test facilities, such as manufacturers’ pump test facilities or laboratories.<\/p>\n
It can be applied to pumps of any size and to any pumped liquids which behave as clean, cold water.<\/p>\n
This International Standard specifies three levels of acceptance:<\/p>\n
grades 1B, 1E and 1U with tighter tolerance;<\/p>\n<\/li>\n
grades 2B and 2U with broader tolerance;<\/p>\n<\/li>\n
grade 3B with even broader tolerance.<\/p>\n<\/li>\n<\/ul>\n
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.<\/p>\n
