This Standard specifies the requirements for components, ancillary equipment and management systems used as a part of the boiler pressure and energy generating systems, including management systems, combustion equipment, water level security, safety valves, general valves and fittings, blowdown connections and integral piping.NOTE: Ancillary equipment and its installation, which form part of the support system, e.g. feed water supply, plant piping, and environmental equipment, are covered in AS 3892.This Standard is intended to-(a) establish the requirements for boiler management systems for all levels of automated operation, and to include controls, interlocks, electrical systems and other safety systems; (b) establish the minimum requisite fittings and valves such as safety valves and blowdown valves; (c) establish selection criteria for energy input equipment such as combustion equipment and the requirements for interfacing with the boiler design; and (d) form a bridge between the design codes (AS 1228, AS 1271, AS 1797) and AS 3892.
