1.1 SCOPE
This Standard specifies criteria for determining the ha7ard levels of various types of pressure equipment to AS/NZS 1200. hut not including gas cylinders. Ii also classifies fluids for use with pressure equipment.
1.2 OBJECTIVE
This Standard is intended to provide a uniform, practical. generic system for assessing the level of hazard associated with various pressure equipment, i.e. the potential to harm people, or damage property and the environment a.s a consequence of pressure equipment loss of containment by rupture, serious leakage or collapse.
These hazard lcvcls may be used for a number of purposcs including—
(a) selecting the appropriate levels of control for safety purposes and risk management; (b) providing a basis for registration or notification of boilers and pressure vessels and
their design with ainhorities: and
(C) providing a basis for in-service inspection of pressure equipment.
1.3 APPLICATION
I his Standard is intended to be used in the design, manufacture, inspection, conformity assessment, use and ultimate disposal of pressure equipment.
The hazard levels determined by this Standard are minimum values and may need in certain cases to be increased.
NOTE: The National Standard for Plant, NOHSC: 1010(1994)， and subsequent State and Territory regulations usually reference this Standard (or AS 3920.1) and require design registration or notification for boilers and pressure vessels of hazard levels A, B, C and D and
registration of such equipment with hazard levels A, B or C.
