Bibliography

This document specifies the rules of design, type testing and inspection during manufacturing, ratings and classification of mobile fire extinguishers and test method to be used. It applies to mobile fire extinguishers with a total mass above 20 kg. This document is limited to water based and powder mobile extinguishers with a maximum allowed pressure PS of 30 bar. This document applies to mobile fire extinguishers with a nominal content of 50 kg (powder) and 45 l or 50 l (water, water based and foam) that are manoeuvred by an operator on foot only.It does not cover fire tests for class C fires, but powder extinguishers are effective on this type of fire. Class D fires are considered to be a very specialist application and are not included in this document, but may be made the object of national specification.NOTEThis document does not specify any metallic materials which comply with the essential requirements of the Directive 97/23EEC (PED). Materials that successfully pass the essential requirements of the PED may be used.
