Machinery vibration standards

Abstract

Over the past 20 years the use of vibration measurement has grown rapidly in the areas of machinery mechanical condition monitoring and evaluation. As a result of this growth, a number of measurement techniques and measurement parameters have evolved. While there has been some commonality in these techniques and parameters, it has often been found difficult to compare machine condition when the same techniques and parameters were not used. Other associated problems have also resulted. This variability in techniques and parameters indicated a real need for vibration measurement standardization within the United States, and throughout the world. To meet this need, standardization committees were formed by the American National Standards Institute (ANSI) to handle U.S. standardization requirements, and by the International Standards Organization (ISO) to produce vibration standards acceptable on a worldwide basis. Vibration Standards offer a potential of a number of advantages: (1) machinery purchase specification simplification, (2) machine design guidelines, (3) machine evaluation criteria, (4) a more useable data base, and (5) easier interchange of technical information. As a result of these advantages, a number of national (ANSI) and international (ISO) machinery vibration standards have been developed. This paper reviews those machinery vibaration standards which have been published, as well as those which are in‐process and planned.
