scope:

This standard covers testing of rotodynamic pumps, up to 150 kW (200 hp), hereafter in this document referred to as pumps, establishing minimum testing protocols for verification of pump efficiency conforming to US Department of Energy (DOE) regulations.

HI 40.6 is intended to be used for efficiency testing at accredited pump test facilities, such as manufacturers' pump test facilities or laboratories only. Industry experience shows that it is very difficult to perform measurements accurate enough to satisfy the requirements in this standard when testing is performed in the field. Therefore field-testing is not permitted as a method of efficiency testing per this standard.

This standard applies to a bare pump by itself without any fittings, unless fittings are an integral part of the pump. In that case, the losses for these components must be included in the performance of the pump. A bare pump is defined as a rotodynamic machine constructed with fluid inlet and outlet sections and input shaft to drive it. The exception is a vertically suspended pump where this includes only the bowl assembly. A fitting is an upstream or downstream component that is not integral to the construction of the pump.

This standard is not intended for production pump testing. Refer to ANSI/HI 14.6 Rotodynamic Pumps for Hydraulic Performance Acceptance Tests and ANSI/HI 11.6 Rotodynamic Submersible Pumps for Hydraulic Performance, Hydrostatic Pressure, Mechanical, and Electrical Acceptance Tests for production pump testing.
