17、andard may involve hazardous materials, operations, and equipment. This International Standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this International Standard to establish appropriate safety and health practices and

18、determine the applicability of regulatory limitations prior to use.1 ScopeThis International Standard specifies the requirements for petroleum fuels for gas turbines (see ISO 3977) used in public utility, industrial, and marine applications. It does not cover requirements for gas turbine fuels for a

19、viation 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

20、recommendations for the quality of the fuel entering the turbine combustion chambers are provided in Annex B.The terminology used and the test methods referred to in these specifications are presented in Annex C.NOTE 1 Additional information on fuels for gas turbines is given in ISO 3977.NOTE 2 The

21、requirements for petroleum fuels for diesel engines and steam turbines for marine use are given in ISO 8217.The fuel categories in this International Standard have been classified in accordance with ISO 8216-2:1986.2 Normative referencesThe following documents, in whole or in part, are normatively r

27、shall be a homogeneous mixture of hydrocarbons, free from inorganic acids and adventitious foreign matter.NOTE Guidelines for limits for trace metals for fuels entering the turbine combustion chambers are contained in Annex A.3.2 Fuels of all categories shall remain homogeneous during storage and ha

However, certain met

29、als, even in trace quantities, are detrimental to gas turbine service life. Information on the significance and concentration of critical metallic elements in the fuel as it enters the turbine combustion chambers is provided in Annex B.4.1 The various categories of gas turbine fuels shall conform to

30、 the limiting requirements shown in Table 1 when the fuel is tested by the methods specified.4.2 Incorporation of additives by the fuel supplier for legal purposes or to improve certain aspects of performance is permitted, provided that the amount and type incorporated do not cause the additive-trea

31、ted fuel properties to fall outside the general requirements and specification limits laid down in Table 1.NOTE Additives may also be introduced subsequent to delivery, as noted in Annex C.4.3 A limit for low-temperature operability is a requirement of this International Standard, but limits cannot

32、be included in Table 1 because of the need to conform to local or national requirements. When this specification is called up, such limits, together with the test methods required, shall be stated.Information on internationally available test methods for low-temperature operability is given in Annex

33、 C (C.2.5).5 SamplingSampling for the requirements in Table 1 shall be carried out by the methods described in ISO 3170, ISO 3171, or equivalent International Standards.NOTE If sampling for trace metals is agreed upon by the interested parties, the recommendations in Annex B should be followed.6 Pre

34、cision and interpretation of test resultsThe majority of test methods specified in Table 1 contain a statement of the precision (repeatability and reproducibility) to be expected from it. Attention is drawn to ISO 4259, which covers the use of precision data in the interpretation of test results; th
