Description

This Standard specifies hydraulic performance tests for acceptance of rotodynamic pumps (centrifugal, mixed flow and axial pumps). It is applicable to pumps of any size and to any pumped liquids behaving as clean cold water. 

This standard is identical with and has been reproduced from ISO 9906:1999.

Scope

This 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 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.
