Foreword
This document (prEN 1366-11:2010) has been prepared by Technical Committee CEN/TC 127 “Fire safety in
buildings”, the secretariat of which is held by BSI.
This document is currently submitted to the CEN Enquiry.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association.
EN 1366, Fire resistance tests for service installations, consists of the following parts:
 Part 1: Ducts
 Part 2: Fire dampers
 Part 3: Penetration seals
 Part 4: Linear joint seals
 Part 5: Service ducts and shafts
 Part 6: Raised access floors and hollow floors
 Part 7: Closures for conveyors and trackbound transportation systems
 Part 8: Smoke extraction ducts
 Part 9: Single compartment smoke extraction ducts (in course of preparation)
 Part 10: Smoke control dampers
 Part 11: Fire Protection system for essential services (in course of preparation)

Introduction
The purpose of this test is to evaluate the ability of the protective system to allow cables plus components of
their installation (connectors, glands, junctions, mountings, etc.) to maintain during a defined time a reliable
function whist exposed to fire. Therefore cables are used with worst case behaviour in fire (high temperature)
as indicator that the fire protective system gives the necessary protection during a given time period.
CAUTION — The attention of all persons concerned with managing and carrying out this fire
resistance test is drawn to the fact that fire testing may be hazardous and that there is a possibility
that toxic and/or harmful smoke and gases may be evolved during the test. Mechanical and
operational hazards may also arise during the construction of the test elements or structures, their
testing and disposal of test residues.
An assessment of all potential hazards and risks to health should be made and safety precautions should be
identified and provided. Written safety instructions should be issued. Appropriate training should be given to
relevant personnel. Laboratory personnel should ensure that they follow written safety instructions at all times.
1 Scope
This part of EN 1366 describes a method to evaluate the maintenance of circuit integrity of electrical cable
systems and associated components (connectors, glands, junctions, mountings, etc.) under fire conditions to
classify the protective system according to EN 13501-3. The test examines the behaviour of cable protection
systems exposed to fire from outside.
This standard is used in conjunction with EN 1363-1.
The test results apply to fire protective systems for electrical cable systems rated for voltages up to 1 kV.
NOTE This test procedure may be used to determine the functionality for optical and data cables in case of fire but
this does not form part of the classification procedure.
The protection system may include ventilation devices, inspection hatches, fixed or removable lids etc.
The tests specified in this standard are not aimed for assessing the performance of sprayed or painted
coatings (e. g. intumescent or ablative coating, plastic film, epoxy resin) and similar protective layers (e.g.
wrap, bandage) applied directly on the cables or bus bars as fire protective system. Also cables and bus bars
with intrinsic resistance to fire are excluded.
This method is very different to EN 50200 and also to IEC 60331-11, -21, -23 and -25, which are not designed
for fire protective systems for electrical cable systems.
This test method is not applicable for cabinets for electrical accessory containing bus systems, relays or
similar.
