The Hydraulic Institute (HI) announces that both the Centrifugal Pump Test Standard (ANSI/HI 1.6 − 2000) and the Vertical Pump Test Standard (ANSI/HI 2.6 − 2000) have been superseded by the newly released Standard for Rotodynamic Pumps for Hydraulic Performance Acceptance Tests, (ANSI/HI 14.6 − 2011). The new test standard contains significant updates from the 2000 version(s) and is considered the new global reference for testing centrifugal and vertical pumps.

ANSI/HI 14.6 − 2011 includes six (6) acceptance grades instead of two (2) that were included in the 2000 versions. Tolerance bands have been developed that will be of interest to those concerned with energy efficiency. Acceptance grades with bilateral tolerances and acceptance grades with unilateral tolerances are defined. Default acceptance grades based on the purchaser’s application are available to guide the pump community (used when there is no specific test acceptance grade in the contract document). The standard contains tolerances for pumps with low horsepower input.
