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Centrifugal Pump Test Standard (ANSI/HI 1.6 − 2000) and the Vertical Pump Test Standard (ANSI/HI 2.6 − 2000) have been superseded by the newly released Standard for Rotodynamic Pumps for Hydraulic Performance Acceptance Tests, (ANSI/HI 14.6 − 2011).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.

The standard features an updated layout of the test arrangement and appendices containing information regarding measuring equipment, string tests, and discrete test parameters.  New graphics and content provide readers with insight into NPSH testing.  In addition, it contains special test techniques related to model testing to predict performance of pumps to large to test by conventional means.

HI Technical Director, Gregg Romanyshyn stated, “This significantly updated test standard for rotodynamic pumps is destined to become the new global reference for factory testing of pumps” adding that, “all members of the pump community will want to ensure that they have a copy of this newly released test standard.”

Test Standard (14.6 − 2011) is available at the HI eStore in PDF format for $195.00.  Hardcopy formats will be ready to ship on or before September 22, 2011.  HI Members enjoy a 25% discount.  Contact Publications@Pumps.org for further information or assistance ordering.
