Provides general requirements for portable fire extinguishers, including the materials, design, construction, methods of manufacture, performance of the extinguisher and any associated gas container, including requirements for instructions and markings.

This Standard specifies requirements for portable fire extinguishers. It covers materials, methods of manufacture and performance of the extinguisher and any associated compressed gas container, instructions and markings.Specific requirements for individual types of fire extinguishers are given in AS/NZS 1841.2, AS/NZS 1841.3, AS/NZS 1841.4, AS/NZS 1841.5, AS/NZS 1841.6, AS/NZS 1841.7 and AS/NZS 1841.8A portable fire extinguisher is generally referred to in this Standard as an extinguisher or the extinguisher and typical components used in portable fire extinguishers are illustrated in Figure 1.1.Manufacturers making a statement of compliance with this Australian/New Zealand Standard on a product, or on packaging or promotional material related to that product, should ensure that such compliance is capable of being verified.
