European foreword
This document (prEN 13501-3:2021) 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 European Commission and the
European Free Trade Association.
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: fire resistant ventilation ducts and fire dampers and power, control and
communication 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) 2000/367/EC
of 03/05/2000 amended by 2003/629/EC of 27/08/2003 and 2011/232/EC of 11/04/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.
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.
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:
— intri
