European foreword
This document (EN 50200:2015) has been prepared by Working Group 10 of CLC/TC 20 “Electric cables”.
The following dates are fixed:
• latest date by which the document has to be implemented at (dop) 2016-09-14
national level by publication of an identical national
standard or by endorsement
• latest date by which the national standards conflicting with the (dow) 2018-09-14
document have to be withdrawn
This document supersedes EN 50200:2006.
The main changes compared to EN 50200:2006 are as follows (minor changes are not listed):
– detailed procedures for metallic data cables and for optical fibre cables have been removed as they are
now given in the relevant standards of CLC/TC 46X and CLC/TC 86A. These standards refer to
EN 50200 for the basic test method;
– recasting and extension of the existing Annex D into two new Annexes, Annex B “Field of direct
application and extended application of test results (Electric power and control cables with rated voltage
up to and including 600 V/1 000 V) and Annex D “Information regarding classification”.
The cable is tested in a representative installed condition, under conditions of minimum bending radius, and
the test is based upon a constant temperature attack at a minimum test temperature of 830 °C. This is typical
of the gas temperature reached after 30 min exposure to the time/temperature conditions prescribed in
EN 1363-1.
The test method in this document includes exposure to fire with mechanical shock under specified conditions
and satisfies the requirements of Mandate M/117 for the PH classification. This European Standard also
includes (Annex E) a means of applying a water spray to the cable during the test, which is not required
under Mandate M/117.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CENELEC [and/or CEN] shall not be held responsible for identifying any or all such patent rights.
This document has been prepared under a mandate given to CENELEC by the European Commission and
the European Free Trade Association.
1 Scope
This European Standard specifies the test method for cables designed to have intrinsic resistance to fire and
intended for use as emergency circuits for alarm, lighting and communication purposes.
This European Standard is applicable to cables for emergency circuits of rated voltage not exceeding
600 V/1 000 V, including those of rated voltage below 80 V and optical fibre cables.
This European Standard includes details for the specific point of failure, continuity checking arrangement,
test sample, test procedure and test report relevant to electric power and control cables with rated voltage up
to and including 600 V/1 000 V. Details for the specific point of failure, continuity checking arrangement, test
sample, test procedure and test report relevant to copper data and telecom cables and optical cables are
given in the relevant standards of
