Describes a procedure for measurement and evaluation of the external mechanical vibration behaviour of generating sets at the measuring points stated in ISO 8528. Applicable to RIC engine-driven AC generating sets for fixed and mobile installations with rigid and/or resilient mountings. Suitable for land and marine use, not including generating sets used by aircraft or to propel land vehicles and locomotives.
