Scope

This document describes the procedures for measuring and evaluating the specified
external mechanical vibration characteristics of the generator set at specified
measurement positions.
This document is applicable to fixed and mobile AC generator sets driven by
reciprocating internal combustion engines with rigid and/or elastic mounting. This
document is applicable to land and marine use, not to generator sets used in aviation or
generator sets used to drive land vehicles and locomotives.
For some specific applications (such as power supply to hospitals, high-rise buildings,
etc.), additional requirements are required. The provisions of this document are
regarded as the basis for these applications.
For generator sets driven by other reciprocating prime movers (such as biogas engines,
steam engines, etc.), the provisions of this document are regarded as the basis for these
applications.
