FOR GAS TURBINES-NEW STANDARD RATING POINT

Because the rating standard for gas turbines in the United States has been equivalent to the pressure and temperature of an elevation of 1000 ft., while European rating was for a sea level condition and a different temperature, American gas turbines suffered a 15 percent penalty when compared to the ratings of European manufactured gas turbines. This was remedied in 1968; the International Council on Combustion Engines established the standard gas turbine rating at 15 degrees C (59 degrees F) and 760 mm Hg(a) pressure (sea level). In 1969 the International Standards Organization accepted the above rating standard with the addition of a relative humidity of 60 percent. Use of this proposed rating standard in the United States will eliminate confusion over outputs of gas turbines. In addition, special ratings for specific operating conditions can still be supplied if requested.
