The purpose of this recommendation is to provide standard procedures and rules for the conductance and reporting of acceptance tests in order to determine: power, thermal efficiency and other performance characteristics of gas turbine power plants. The recommendation defines standard conditions which shall be used if no other conditions are agreed at the time of purchase. The recommendation also provides methods for correcting results obtained under test conditions to standard or other specified conditions. This document is not intended to provide a basis for the conductance of test work generally aimed at development or research.
The recommendation applies to open cycle gas turbine power plants using a normal combustion system. It has been extended to also include closed and semi-closed cycle gas turbine power plants. In case of gas turbines using free piston gasifiers or special heat sources (eg., chemical process, nuclear reactions, furnace for a supercharged boiler) the code may be used as a basis but will require to be suitably modified.
