Understanding the differences between the legacy standard, PTC 4.1, and its successor, PTC 4, is crucial for modern engineers. The newer code was intended to correct many of the older code's deficiencies. A comparison of their key features is summarized in the table below.
ASME PTC 4.1-1964 (reaffirmed 1991) provides a simplified, widely used method for determining steam generator efficiency, often favored for routine testing over the more rigorous, modern PTC 4-1998 standard. It utilizes either the Input-Output (direct) or Heat Loss (indirect) method to calculate efficiency, with the latter generally offering higher accuracy.

This method calculates efficiency directly by measuring the heat absorbed by the working fluid (water/steam) and dividing it by the heat input from the fuel.
