The history of overall vibration measurements in North America and Europe goes back to the 1950s. Over the decades, there have been many misunderstandings related to this subject. The sources of the misunderstanding will be described.

Currently, there is a trend to try to use overall vibration measurements for screening vibrations in selected areas, such as reciprocating compressors and piping. One such guideline has been developed and published by the European Forum for Reciprocating Compressors (EFRC). It will soon be an ISO Standard.

A new standard for high speed reciprocating compressors is nearing completion, and will be discussed. It will also provide guidance for using overall vibrations as a screening tool.
