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 Ю Clause 5 and the relevant field of application procedures O.
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 Br00f without testing. This information is given in the Commission Decision of 2000-09-06 establishing the list of products belonging to Classes BR00f (Decision 2000/553/EC).
E) NOTE Test reports constitute the basis for extended application reports as explained in prEN 15725. ElScope
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 ®J.
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.

Classes of external fire performance of roofs/roof coverings
The classification set out in this European Standard is based upon the test methods contained in ENV 1187:2002. That standard incorporates four distinct test methods that correspond to different fire hazard scenarios. There is no direct correlation between the test methods and hence no generally acceptable hierarchy of classification between them.
Products classified in a given class are deemed to satisfy all the requirements of any lower class for the same test method/fire hazard scenario. The classes with their corresponding fire performance are given in Tablet.
Test methods
General
The four test methods given in ENV 1187 are those to be used for classification purposes for roofs/roof coverings. The selection of the tests to be carried out is specified in 6.3. The classification parameters, the classes and the corresponding criteria are specified in Clauses 8 and 9.
Test 1: Method with burning brands
The test evaluates the performance of a roof under the conditions of thermal attack with burning brands. The performance includes the fire spread across the external surface of the roof, the fire spread within the roof and the fire penetration.
Test 2: Method with burning brands and wind
The test evaluates the performance of a roof covering under the conditions of thermal attack with burning brands and additional wind. The performance includes damaged length both on the roof covering and in the substrate.
Test 3: Method with burning brands, wind and supplementary radiant heat
The test evaluates the performance of a roof under the conditions of thermal attack with burning brands, additional wind and radiant heat. The performance includes the external fire spread and the fire penetration.
Test 4: Two stage method incorporating burning brands, wind and supplementary radiant heat
The test evaluates the performance of a roof under the conditions of thermal attack with burning brands, wind and radiant heat. The performance includes the external fire spread and the penetration by fire.
Principles for specimen preparation, testing and classification
General requirements for specimen preparation
Before testing, the test specimens shall be prepared and conditioned and, where relevant, mounted in accordance with the relevant test method and product standards or other technical specifications.
The external fire performance of a roof/roof covering includes such aspects as external and internal fire spread, external and internal damage, fire penetration and the occurrence of flaming droplets or debris. The external fire performance of a roofAoof covering therefore does not only depend on the burning behaviour of the exposed surface, the roof covering, but also on the influences of several components of the roof, such as the nature and thickness of insulating layers and vapour barriers together with their supporting elements. It may also depend on the systems of attachment of all components, e g. glued or mechanically fastened.
Therefore, the test specimens shall be representative, in all details of practical application with regard to:
substrate and deck;
type, the number and the joining of all layers of roofing materials (including any insulation, vapour barriers, etc.);
fixing of the layers.
In order to reduce the amount of testing, individual test methods specify standard specimen arrangements, covering a wider field of application.
Such standard specifications concern e.g. the supporting decks and substrates, and the types and positioning of joints.
