Formally titled "Steam Generating Units," ASME PTC 4.1 is a Code established by the American Society of Mechanical Engineers (ASME) Performance Test Codes (PTC) committee. Originally published in 1946 and revised most notably in 1964 (with reaffirmations thereafter), the 4.1 version specifically addresses the and Indirect Method (Heat Loss) for determining boiler efficiency. Originally published in 1946 and revised most notably
