Standards Development


The Vibration Institute and Acoustical Society of America (ASA) would like to invite all interested parties to participate in the development of an American National Standards Institute (ANSI) industry standard pertaining to shaft alignment methodology concerning large industrial rotating apparatus.

The Vibration Institute is forming a working group to undertake the task of creating a standard with broad industry acceptance which will cover basic technical information on machinery shaft alignment. This standard will focus on alignment activity and results - not the technician. It will contain considerations, methodologies and acceptance tolerances, forming the basis of effective shaft alignment without bias to tool or instrument brand. The standard’s core technical components of Measure, Analyze, Correct and Document will lead to acceptably aligned machines, and will address alignment types, accurate shaft rotational centerline and mechanical run-out measurements, machinery deterioration, baseplate preparation, offline-to-running movement, and acceptance tolerances based on coupling types used. The standard will apply to horizontally or vertically arranged, direct connected industrial machinery utilizing flexible or rigid coupling methods.

If you, or a colleague, are interested in participating in this exciting new standard, please complete the online form at http://www.vi-institute.org/vi-initiatives/alignment-standard-asa-application/ or submit your information via email to ASC_S2_WG15@vi-institute.org

The participation deadline was January 31, 2014, thank you for your interest.
