Scope: This standard is incorporated by reference in the Uniform Test Procedures for “Pumps” and “Dedicate Purpose Pool Pumps” as outlined in the Department of Energy - Energy Conservation Program (  This standard established minimum testing protocols for testing of rotodynamic pumps for determination of pump efficiency in a uniform manner.

HI 40.6 is intended to be used 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 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.
