European foreword
This document (prEN 13501-3:2019) 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 will supersede EN 13501-3:2005+A1: 2009.
This document has been prepared under a Mandate given to CEN by the Commission of the European
Communities and the European Free Trade Association.
CEN, CENELEC and EOTA committees preparing technical specifications which contain performance
requirements against fire resistance tests should make reference to the fire resistance classification
given in this document and not refer directly to any specific fire test method.
EN 13501 consists of the following parts:
— Part 1: Classification using data from reaction to fire tests,
— Part 2: Classification using data from fire resistance tests, excluding ventilation services,
— Part 3: Classification using data from fire resistance tests on products and elements used in building
service installations and electrical cables:,
— Part 4: Classification using data from fire resistance tests on components of smoke control systems,
— Part 5: Classification using data from external fire exposure to roofs tests.
— Part 6: Classification using data from, reaction to fire tests on power, control and communication
cables
Introduction
The aim of this document is to define a harmonized procedure for the classification for resistance to fire
of construction products and elements. This classification is based on the test procedures listed in
Clause 2 and the relevant field of application procedures.
This document is prepared in support of the second essential requirement in the EC Construction
Products Regulation (305/2011), which is detailed in the Interpretative Document number 2 (ID2):
Safety in case of fire (OJ C62 Vol 37). It reflects the Commission Decision (EU) 20XX/XXX of DD MM
20XX as regards the classification of the resistance to fire performance of construction products,
construction works and parts thereof.DD MM 20XX specify performance and classes regarding fire
resistance. These classes are identified by designation letters, each of which refers to an important
characteristic of fire resistance behaviour.
This document provides for a common understanding for these requirements. It interprets the
functional requirements for the different groups of building products and elements and explains the
method for deriving their classification on the basis of test results and/or extended application results
for individual products or elements.
NOTE Test reports constitute the basis for extended application reports as explained in EN 15725.
1 Scope
This document specifies the procedure for classification of the resistance to fire performance of
construction products and building elements used as components of building service installations, using
data from fire resistance tests which are within the direct field of application of the relevant test
method. Classification on the basis of extended application of test results is also included in the scope of
this document.
Products/elements for use in ventilation systems include (excluding smoke and heat exhaust
ventilation):
— fire resisting ducts;
— fire dampers.
Products /elements for use in/as cables systems:
— Intrinsic fire resistant cables/unprotected cables;
— Fire protective systems for cable systems;
— Supporting /suspension devices;
— Associated components (connectors, glands, junctions, etc.)
Relevant test methods which have been prepared for these products/elements are listed in Clause 2.
