It applies to mobile fire extinguishers with a total mass above 20 kg and specified in clause 4 of this standard. This standard is limited to water based and powder extinguishers. 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 standard but, may be made the object of national specification. 2 Normative references This European Standard incorporates by dated or undated references, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.
