Operational Monitoring and Condition Evaluation

Chair: Max L’vov

Scope: Develop and maintain standards for operational condition monitoring and evaluation of machinery. Liaison with the corresponding ISO standards groups. Coordination of the US vote on related or parallel international standards.

Responsible for the following published standards:

• ASA/ANSI S2.28 – Guide for the Measurement and Evaluation of Broadband Vibration of Surface Ship Auxiliary Rotating Machinery
• ASA/ANSI S2.29 – Guide for the Measurement and Evaluation of Vibration of Machine Shafts on Shipboard Machinery
