ICS Code (Gas and steam turbines. Steam engines): 27.040
scope:

This International Standard covers the safety requirements for industrial, commercial, and residential automated stationary microturbine (micro gas turbine) engine generator assemblies with an individual system or subsystem output rating with nominal supply voltages not exceeding 1 000 V for alternating current (A.C.) and not exceeding 1 500 V for direct current (D.C.), 500 kW per individual unit/subsystem or less that are intended for installation and use in ordinary and hazardous location using liquid or gaseous fuels and the safety related control and detection systems and essential auxiliaries for all types of open cycles, closed-cycle, and semi-closed (simple, combined, regenerative, reheat, etc.) used in onshore and offshore applications including floating production platforms.

This International Standard applies to driven machinery only where it is an integral part of the microturbine (e.g. a gearbox integral to the microturbine), or is located within the microturbine enclosure and forms part of the enclosure hazardous area classification (e.g. a generator within the microturbine enclosure), or where the driven machinery has a direct effect on the operational safety of the microturbine.

This International Standard details the anticipated significant hazards associated with microturbines and specifies the appropriate preventative measures and processes for reduction or elimination of these hazards. This International Standard addresses the risks of injury or death to humans and risks to the environment. Equipment damage without risk to humans or the environment is not covered.

Microturbine packages are generally specified using International Standards and national standards. Achieving safety is promoted by using additional safety codes and standards, which are shared by microturbines with other technologies.

NOTE It is necessary to recognize that local legislation in the country in which the equipment is to be put to use might not be covered by this International Standard.

This International Standard approaches microturbine safety from an international perspective, based on the content of existing, recognized ISO and IEC standards to the greatest extent possible. Where no ISO or IEC standard exists, other codes or standards (such as EN, NFPA, etc.) have been included. Where local legislation accepts other established codes or standards, or an alternative international or national standard providing equivalent requirements for achieving the desired tolerable level of risk, the use of these alternative codes or standards in place of the references provided in Clause 2 is permissible.

This International Standard excludes microturbines used primarily for direct and indirect propulsion, special heat source applications, and in research and development programmes. It also excludes microturbines for compressed-air energy storage plants. Where appropriate, this International Standard can be used to give general guidance in such applications.

This International Standard is not applicable to machinery or safety components that were manufactured before the date of its publication as an International Standard
