Describes the rules of design, type testing and inspection during manufacturing, ratings and classification of mobile fire extinguishers and test methods to be used.

This European Standard specifies the rules of design, type testing and inspection during manufacturing, ratings and classification of mobile fire extinguishers and test methods to be used. It applies to mobile fire extinguishers with a total mass above 20 kg for powder, water based and CO2 extinguishers. This standard applies to mobile fire extinguishers that are manoeuvred by an operator on foot only. It does not cover fire tests for class C and class F fires, but the used extinguishing media can be effective on these types of fire. Class D fires are considered to be a very specialist application and are not included in this standard, but may be made the object of national specification.
