But in the newer editions, that paragraph was missed, and the API code ask the users to use such a standard of Battelle Institute “Investigation and Prediction of Cooling Rates During Pipeline Maintenance Welding and Battelle‘s Hot Tapp Thermal Analysis Mode”.
Can I get a copy of that standard of Battelle Institute.
