ISO 8528-4:2005规定了往复式内燃机发电机组的控制设备和开关设备的标准。 本标准适用于陆上和海上使用的由往复式内燃机（RIC）驱动的交流（a.c.）发电机组，不包括用于飞机或驱动陆上车辆和机车的发电机组。 对于某些特定应用（如基本医院用品和高层建筑），可能需要补充要求。ISO 8528-4:2005的规定应被视为制定任何补充要求的基础。 对于由其他原动机（如蒸汽机）驱动的发电机组，ISO 8528-4:2005应被视为确定这些要求的基础。

ISO 8528-4:2005 specifies the criteria for controlgear and switchgear for generating sets with reciprocating internal combustion engines. It applies to Alternating Current (a.c.) generating sets driven by Reciprocating Internal Combustion (RIC) engines for land and marine use excluding generating sets used on aircraft or to propel land vehicles and locomotives. For some specific applications (e.g. essential hospital supplies and high-rise buildings), supplementary requirements may be necessary. The provisions of ISO 8528-4:2005 should be regarded as a basis for establishing any supplementary requirements. For generating sets driven by other prime movers (e.g. steam engines) ISO 8528-4:2005 should be regarded as a basis for establishing these requirements.
