scope:

This document specifies noise test codes for determining the sound power level and the emission sound pressure level at the workstation of reciprocating internal combustion engine driven electrical power generating sets.

This document applies to constant and variable-speed reciprocating internal combustion (RIC) engine driven alternating current (AC) and direct current (DC) generating sets for fixed and mobile applications with rigid or flexible mountings. It is applicable for land and marine use, excluding generating sets used on aircraft or to propel land vehicles and locomotives.

NOTE 1 For some specific applications (e.g. essential hospital supplies, high-rise buildings) supplementary requirements can be necessary. The provisions of this document can be regarded as a basis.

NOTE 2 This document is referenced with regard to noise in ISO 8528-13:2016, which contains requirements concerning the design of generating sets, verification of noise levels and information related to noise in the operating and maintenance instructions.
