Overview
The American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code (BPVC) establishes rules of safety governing the design, fabrication and inspection of boilers and pressure vessels. All boilers must have a data plate on the side of the boiler or on the heat exchanger that details when the boiler was made, the manufacturer that certified the boiler, the maximum allowable working pressure, maximum allowable temperature, input firing rate, output firing rate, minimum relief valve capacity and the boiler type.
