BS 4066-3: 1994 IEC 332-3: 1992 : Tests on electric cables under fire conditions — Part 3: Tests on bunched wires or cables — (Implementation of CENELEC HD 405.3 S1)

This Part of BS 4066 has been prepared under the direction of the Cables and
Insulation Standards Policy Committee. It implements HD 405.3 S1:1993 which
was published by the European Committee for Electrotechnical Standardization
(CENELEC). It is identical with IEC 332-3:1992 Tests on electric cables under fire
conditions — Part 3: Tests on bunched wires or cables, published by the
International Electrotechnical Commission (IEC). This Part of BS 4066
supersedes BS 4066-3:1986, which is withdrawn.
It should be noted that IEC 332-3:1992 is a Technical Report of type 2. It is not to
be regarded as an international standard. A review of IEC 332-3:1992 will be
carried out not later than 3 years after its publication with the options of
extension for another 3 years, conversion into an international standard, or
withdrawal.
Additional guidance is given in National annex NB on test sample mounting.
Part 1 of BS 4066 specifies a method of test on a single vertical insulated wire or
cable and the requirement for compliance.
Part 2 of BS 4066 specifies a method of testing a small insulating wire under fire
conditions when the method specified in BS 4066-1 is not suitable because some
small conductors may melt during application of the flame. Part 2 of BS 4066 also
includes the requirement for compliance.
The foreword of HD 405.3 makes reference to the “date of withdrawal” (dow) of
the relevant national standard. In this case, the relevant national standard is
BS 4066-3:1986. Certificates and marks already awarded may continue to apply
to production until 1 March 1999.
A British Standard does not purport to include all the necessary provisions of a
contract. Users of British Standards are responsible for their correct application.
