ASME PTC 4.1, formally known as the "Performance Test Code for Steam Generating Units," is an internationally recognized standard developed by the American Society of Mechanical Engineers (ASME). First published in 1964 and reaffirmed in 1991, this code established consistent, reliable procedures for determining the of industrial boilers. As prescribed by the code, a boiler's fuel-to-steam efficiency—a measure of overall heat exchange effectiveness accounting for radiation and convection losses—can be determined using two primary methods.
The standard breaks down efficiency testing into two fundamental approaches, allowing operators to choose the best method for their data availability. Asme Ptc 4.1.pdf BEST
