AS ISO 9906:2018 PDF
Adopts ISO 9906:2012 to specify hydraulic performance tests for customers’ acceptance of rotodynamic pumps (centrifugal, mixed flow and axial pumps, hereinafter “pumps”).
The tests in this International Standard are intended to ascertain the performance of the pump and to compare this with the manufacturer’s guarantee.
The nominated guarantee for any quantity is deemed to have been met if, where tested according to this International Standard, the measured performance falls within the tolerance specified for the particular quantity.
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 can be applied to pumps of any size and to any pumped liquids which behave as clean, cold water.
This International Standard specifies three levels of acceptance:
— grades 1B, 1E and 1U with tighter tolerance;
— grades 2B and 2U with broader tolerance;
— grade 3B with even broader tolerance.
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.
