The document is written and maintained by volunteers chosen for their technical expertise. Such vessels may be fired or unfired. This division of section viii provides requirements applicable to the design fabrication inspection testing and certification of pressure vessels operating at either internal or external pressures exceeding 15 psig. The asme bpvc certification program conforms to the rules governing the design fabrication assembly and inspection of boiler and pressure vessel components during construction.

The asme boiler pressure vessel code bpvc is an american society of mechanical engineers asme standard that regulates the design and construction of boilers and pressure vessels.

As per asme section viii 1 ug 99 the pressure vessels designed for internal pressure shall be subjected to a hydrostatic test pressure which at every point in the vessel is at least equal to 1 3 times the mawp multiplied by the lowest ratio for the materials of which the vessel is constructed of the stress value s for the test temperature on. Asme unfired pressure vessel code the original unfired pressure vessel code section viii as prepared by the asme boiler code committee was concerned largely with riveted construction. 8 asme s boiler and pressure vessel code bpvc 2013 pressure vessels continued division 2.
