Foreword
This classiciation of fires was first established by
CEN in 1968 in the Unification Document
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 2 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 2 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 European Standard:
Austria, Belgium, Denmark, Finland, France,
Germany, Greece, Iceland, Ireland, Italy,
Luxembourg, Netherlands, Norway, Portugal,
Spain, Sweden, Switzerland and United Kingdom
This European Standard shall be given the status of
a national standard, either by publication of an
identical text or by endorsement, at the latest by
April 1993, and conflicting national standards shall
be withdrawn at the latest by April 1993

2 Definition and designation of
Trang 7© BSI 03-1999 3
0 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
1 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
2 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
