Fire classification of construction products and building elements - Part 3: Classification using data from fire resistance tests on products and elements used in building service installations: fire resisting ventilation ducts and fire dampers and/or power, control and communication cables

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.
Construction products or building elements for use in ventilation systems include (excluding smoke control system):
-   fire resisting ventilation ducts;
-   fire dampers.
Construction products or building elements for use in or as cables systems:
-   unprotected electric cables with intrinsic fire resistance;
-   Fire protective systems for cable systems and associated components.
Relevant test methods which have been prepared for these construction products/building elements are listed in Clause 2.
NOTE   Cables associated with fire dampers are not generally covered by this document unless there is a local regulation that requires it.

European foreword
This document (prEN 13501-3:2023) 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.
In comparison with the previous version EN 13501-3:2005+A1:2009 of edition EN 13501-3:2005, the
following technical modifications have been made:
— paragraphs related to fire protective systems for electric cable systems; unprotected electric cables
with intrinsic fire resistance; unprotected small electric cables with intrinsic fire resistance the
added paragraphs are: 5.1.5; 5.1.6; 5.1.7; 6.5.3; 6.5.4; 6.5.5; 7.2.4; 7.2.5; 7.2.6. Improving the text by
replacing Declaration of fire resistance performance by Declaration of fire resistance classification
avoiding the misinterpretation in relation with the text in regulation n° 305/2011/EC;
— adding an Annex B (normative) on Additional fire damper classifications if declared.
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

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 11/04/2011 as regards
the classification of the resistance to fire performance of construction products, construction works and
parts thereof. XXX/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 bu
