Specifies requirements for components, ancillary equipment, and management systems used as part of the boiler pressure and energy-generating system, including combustion equipment, water level security, safety valves and other fittings, blowdown connections and integral piping. Most of the requirements in This Standard are currently in AS 1228, Boilers - Water-tube, and AS 1797, Boilers - Fire-tube, shell and miscellaneous, with some requirements similar in both Standards, while others are different. The requirements have been reviewed, and as far as practicable, uniform requirements have been proposed in This Standard which will be applicable to all types of boilers. It is intended that all such requirements shall be withdrawn from AS 1228 and AS 1797 at their next revision.
