DANSK DS/ISO 4261 PDF

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.
