This 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 aviation use. This International Standard is intended for the guidance of users such as turbine manufacturers, and 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 Annex B. The rec­ommendations of Annex B as well as additional modifications by the gas turbine manufacturer may, however, be specified by mutual agreement between the interested parties.

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

Nothing in these specifications shall preclude observance of legal or fiscal regulations that may be more restrictive.

NOTE 1       Additional information on fuels for gas turbines is given in ISO 3977.

NOTE 2       The 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, Petroleum products — Fuels (class F) — Classification — Part 2: Categories of gas turbine fuels for industrial and marine applications.

This European Standard describes the specific functional requirements for the design, construction, operation, maintenance and disposal activities for safe and secure gas compressor stations.

This European Standard applies to new gas compressor stations with a Maximum Operating Pressure (MOP) over 16 bar and with a total shaft power over 1 MW. For existing compressor stations this European Standard applies to new compressor units. Where changes/modifications to existing installations take place, due account may be taken of the requirements of this European Standard.

This European Standard does not apply to gas compressor stations operating prior to the publication of this European Standard.

The purpose of this European Standard is intended to

       ensure the health and safety of the public and all site personnel

       to cover environmental issues and

       to avoid incidental damage to nearby property.

This European Standard specifies common basic principles for the gas infrastructure. Users of this European Standard should be aware that more detailed national standards and/or codes of practice may exist in the CEN member countries.

This European Standard specifies common basic principles for gas infrastructure. Users of this European Standard should be aware that more detailed national standards and/or code of practice may exist in the CEN member countries.

This European Standard is intended to be applied in association with these national standards and/or codes of practice setting out the above-mentioned basic principles.

In the event of conflicts in terms of more restrictive requirements in national legislation/regulation with the requirements of this European Standard, the national legislation/regulation shall take precedence as illustrated in FprCEN/TR 13737. FprCEN/TR 13737 gives:

       clarification of all legislations/regulations applicable in a member state;

       if appropriate, more restrictive national requirements;

       a national contact point for the latest information.

This European Standard does not apply to:

       off-shore gas compressor stations;

       gas compressor stations for compressed natural gas filling-stations;

       customer installations downstream of the point of custody transfer;

       design and construction of driver packages (see Annex C).

For supplies to utility services such as small central heating boilers reference should be made to EN 1775.

This European Standard specifies a gas chromatographic method for ethanol, in which higher alcohols (propan-1-ol, butan-1-ol, butan-2-ol, 2-methylpropan-1-ol (isobutanol), 2‑methylbutan‑1‑ol, and 3‑methylbutan‑1‑ol) up to 2,5 % (m/m), methanol up to 3 % (m/m) and other volatile impurities, in the range up to 2 % (m/m) are determined.

Due to possible interferences the method is not applicable to denatured ethanol samples.

NOTE          For the purposes of this European Standard, the term “% (m/m)” is used to represent the mass fraction (ω).
