The Hydraulic Institute (HI), with the approval of the American National Standards Institute (ANSI), is in search of qualified individuals in North America to participate in the draft review process for the following updated standards: ANSI/HI 9.1-9.5 Pumps — General Guidelines, ANSI/HI 9.6.2 Rotodynamic Pumps — Assessment of Applied Nozzle Loads, and ANSI/HI 9.6.8 Rotodynamic Pumps — Guideline for Dynamics of Pumping Machinery.

The purpose of ANSI/HI 9.1-9.5 document is to offer guidelines for rotodynamic and positive displacement pump type classifications, materials of construction, airborne sound measurement and procedures for decontamination of returned product.

The purpose of ANSI/HI 9.6.2 document is to offer recommendations for the assessment of applied nozzle loads for different pump types.

The purpose of ANSI/HI 9.6.8 document, which applies to rotodynamic pumps, is to describe and recommend the means for evaluating pumping machinery construction attributes and relevant site characteristics to determine the effects of dynamic performance on equipment life and reliability. It also describes and recommends various levels of detailed evaluation and validation that are commensurate with the degree of equipment uncertainty and application risk.

Individuals and organizations who qualify and are directly and materially affected by these standards are asked to contact the Hydraulic Institute to be included in the ANSI canvas list to review the drafts. This list will be submitted to ANSI in order to meet its open canvas requirements.
