Annex C (informative) - Significance of specifications
        for gas turbine fuels

Provides the requirements for petroleum fuels for gas turbines (see ISO 3977) used in public utility, industrial, and marine applications.

This International Standard specifies the requirements for petroleum fuels for gas turbines (see ISO3977) used in public utility, industrial, and marine applications. It does not cover requirements for gas turbine fuels for aviation use. This International Standard is intended for the guidance of users such as turbine manufacturers, suppliers, and purchasers of gas turbine fuels.

This International Standard sets out the properties of fuels at the time and place of transfer of custody to the user. Further information and recommendations for the quality of the fuel entering the turbine combustion chambers are provided in AnnexB.

The terminology used and the test methods referred to in these specifications are presented in AnnexC.

NOTE 1 Additional information on fuels for gas turbines is given in ISO3977.

NOTE 2 The requirements for petroleum fuels for diesel engines and steam turbines for marine use are given in ISO8217.

The fuel categories in this International Standard have been classified in accordance with ISO8216-2:1986.
