ISO 8528-7:2017 specifies the requirements and parameters for the specification and design of a reciprocating internal combustion (RIC) engine driven generating set, with reference to the definitions given in ISO 8528‑1 to ISO 8528‑6.

It applies to alternating current (a.c.) generating sets driven by RIC engines for land and marine use, excluding generating sets used on aircraft or to propel land vehicles and locomotives.

For some specific applications (for example, essential hospital supplies, high-rise buildings, etc.) supplementary requirements may be necessary. The provisions of this document are intended to be regarded as a basis.

For other reciprocating-type prime movers (e.g. sewage gas engines, steam engines), the provisions of this document are intended to be used as a basis.
