ISO Foreword
ISO (International Organization for Standardization) is a worldwide federation of national standards bodies (ISO group members). The work of formulating international standards is generally carried out through ISO technical committees. Each research body member is interested in a certain subject of an established technical committee and has the right to send representatives to attend the corresponding committee. International organizations, governments and non-governmental organizations also participate in the work in collaboration with ISO. ISO () works closely with the International Electrotechnical Commission (IEC) to study all topics of electrotechnical standardization. The draft international standard adopted by the technical committee is sent to the group members for voting. As an international standard publication, it requires at least 75% of the voting group members to pass.
International Standard ISO8528-1 was developed by SC2* Performance and Test Subcommittee of ISO/TC70 "Technical Committee for Internal Combustion Engines". ISO8528 is under the general title of "AC Generator Sets Driven by Reciprocating Internal Combustion Engines" and includes the following parts: Part 1: Application, Rating and Performance

This standard specifies test methods for the characteristics of complete generating sets. The generating set manufacturer shall be responsible for the specified characteristics and the tests performed.
This standard applies to alternating current (ac) generating sets driven by reciprocating internal combustion (RIC) engines for land and marine use. It does not apply to generating sets for aviation or driving land vehicles and locomotives. For some special purposes (such as necessary hospital power supply, high-rise buildings, etc.), additional requirements may be necessary. This standard specifies the requirements to be made.
For AC generator sets driven by other types of reciprocating prime movers (such as biogas engines, steam engines), the provisions of this standard should be used as the basis.
