Specifies requirements for wheeled fire extinguishers in which the extinguishant can be expelled by either gas stored under pressure in the cylinder or by pressure of gas released from a compressed gas cylinder. This Standard refers to materials, methods of manufacture and performance of the extinguisher and any associated compressed gas container; and also to instructions and markings.

This Standard specifies the requirements for wheeled fire extinguishers in which the extinguishant can be expelled by either gas stored under pressure in the cylinder of the extinguisher or by pressure of gas released from a compressed gas container. This Standard refers to materials, methods of manufacture and performance of the extinguisher and any associated compressed gas container; and also to instructions and markings.Where gases are used as a propellent or to facilitate leak detection that may have ozone depleting properties, consideration should be given to the compliance with the provisions of the Commonwealth Ozone Protection Act 1989 and its regulations.This Standard applies to the following types of wheeled fire extinguishers:(a) Water (gas container).(b) Water (stored pressure).(c) Wet chemical (stored pressure).(d) Foam (gas container).(e) Foam (stored pressure). (f) Powder (gas container). (g) Powder (stored pressure).(h) Carbon dioxide type.(i) Vapourizing liquid type (stored pressure)NOTE: A wheeled fire extinguisher is generally referred to in this Standard as 'an extinguisher' or 'the extinguisher'.
