This Standard sets out requirements for materials, design, construction, inspection and testing of boilers as defined in AS/NZS 1200.

NOTE: The Scope of this Standard covers requirements for cast iron in addition to welded boilers inclusive of vapour-generating and hot fluid units subject to internal vapour or liquid pressure. Other forms of construction should be by agreement between the parties concerned.

This Standard specifically applies to the design and construction of boilers including superheaters, reheaters and economizers.

It also applies to all pressure parts containing fluid up to and including the valves separating the pressure parts from—

(a) steam piping to and from other equipment;

(b) water piping to and from other equipment;

(c) drain piping;

(d) the surrounding atmosphere, except that for safety valves, their vent piping to the atmosphere is also covered; and

(e) for equipment such as reheaters which may not incorporate valves at their supply and return connection points, the Standard applies to the equipment included between the inlet to the inlet header and the outlet from the outlet header of such equipment.

This Standard also provides guidance on locomotive and other heritage boilers, and on the design of blowdown vessels.
