ASME PTC 4.1-1964 provides standardized procedures for calculating steam-generating unit efficiency through both input-output and heat loss methods. While often utilized for routine monitoring, this standard has been largely superseded by ASME PTC 4-2013, which offers improved accuracy for contractual testing. For a review of this standard, refer to the document at NormSplash ASME PTC 4-2013 - NormSplash 14 May 2017 —
