The National Board of Boiler and Pressure Vessel

An external inspection while the boiler is under pressure is suggested midway between the annual inspections. An internal boiler inspection consists of all waterside areas of the vessel (steam, blow-off, and water connections), and fireside conditions, as well as dearators, superheaters, and economizers.
