CENTRI 2/U1 It was subsequently submitted to ballot in November 1971 with a view to its translation into a European Standard, and adopted by CEN on 21 June 1972 On 19 March 1984 CEN adopted an amendment to EN consisting of an addition of an introduction which has been extracted in whole from ISO 3941 (1977) This amendment was considered useful and was requested by CEN/TC 70 at its meeting on 25/26 March 1982 in Milan, as certain countries use or have used a specific class of fire to designate fires in live electrical installations At its meeting held in Paris on 29/30 January 1992 CEN/TC 70 has reconfirmed EN without modifications This version supersedes EN 2:1972 In accordance with the Common CEN/CENELEC Internal Regulations the following countries are bound to implement this

be withdrawn at the latest by April 1993 Contents Foreword Introduction Scope Definition and designation of classes of fires Page 3 © BSI 03-1999 EN 2:1992 Introduction This standard defines classes of fires according to the material undergoing combustion In consequence it does not define a particular class of fire involving an electrical risk Scope The present document classifies in four categories the different kinds of fires which can be defined in terms of the nature of the fuel Such a classification is particularly useful in the context of fire fighting by means of an extinguisher Definition and designation of classes of fires The following designations are for the purpose of classifying fires of different natures and of simplifying spoken and written reference to them: Class A: fires involving solid materials, usually of an organic nature, in which combustion normally takes places with the formation of glowing embers Class B: fires involving liquids or liquefiable solids Class C: fires involving gases Class D: fires involving metals © BSI 03-1999 BS EN 2:1992 National annex NA (informative) Committees responsible The United Kingdom participation in the preparation of
