CEN, CENELEC and EOTA committees preparing technical specifications which contain performance requirements against external fire exposure of roofs should make reference to the classification given in this European Standard 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 components of normal building service installations: fire resisting ducts and fire dampers
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 roof tests.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.
Introduction
The aim of this European Standard is to define a harmonized procedure for the classification of roofs/roof coverings exposed to external fire. This classification is based on the test methods listed in This European Standard has been prepared in support of the second essential requirement in the EC Construction Products Directive (89/106/EEC) and as detailed in the Interpretative Document Number 2: Safety in case of fire (OJ C62 Vol. 37).
The European Commission has drawn up a list of products which, under specified conditions, may be considered to be Class B r00 f without testing. This information is given in the Commission Decision of 2000-09-06 establishing the list of products belonging to Classes B R00 f (Decision 2000/553/EC).
E) NOTE Test reports constitute the basis for extended application reports as explained in prEN 15725. El 1 Scope
This European Standard provides the fire performance classification procedures for roofs/roof coverings exposed to external fire based on the four test methods given in ED ENV 1187:2002 and the relevant extended application rules For the classification of a roof/roof covering, ED only those test methods and those application rules need to be <51 applied for which the corresponding classification is envisaged.
Products are considered in relation to their end use application.
NOTE The distinction between roofs with a steep slope and facades, in terms of the test and classification standard to be applied, may be subject to national regulations.
General information on the four test methods in ENV 1187:2002 is given in Annex A.
