This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by February 2004, and conflicting national standards shall be withdrawn at the latest by February 2004. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of the Construction Products Directive. CEN, CENELEC and EOTA committees preparing technical specifications which contain performance requirements against resistance to fire tests should make reference to the resistance to fire classification given in this standard and not refer directly to any specific fire test method. Some of the methods referred to by this standards are prENs which are still undergoing technical development. Users of this standard should, therefore, check the availability and acceptability of these prENs before seeking to apply them. Currently EN 13501-2 cannot be applied to classify curtain walling for resistance to fire. This will be possible once either EN 1364-3 “Fire resistance tests for non-loadbearing elements Part 3: Curtain walling Full configuration (complete assembly)“ is made available or alternative provisions for classifying curtain walling for resistance to fire are made available. EN 13501 consists of the following parts: Part 1:Classification using test 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 Part 4:Classification using test data from fire resistance tests on smoke control systems Part 5:Classification using test data from external fire exposure to roof tests Annexes A and B are normative. This document includes a Bibliography. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Slovakia, Spain, Sweden, Switzerland and the United Kingdom.

This classification is based on the test procedures listed in clause 2. This Part of this European Standard is prepared in support of the second essential requirement in the EC Construction Products Directive (89/106/EEC) which is detailed in the Interpretative Document number 2 (ID2): Safety in case of fire (OJ C62 Vol 37). It reflects the Commission Decision of 3 May 2000 on the implementation of the Council Directive 89/106/EEC as regards the classification of the resistance to fire performance of construction products, construction works and parts thereof. The Interpretative Document and the Commission Decision of 2 May 2000 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 Part of this European Standard provides for a common understanding for these requirements. It interprets the functional requirements for the different groups of building elements and explains the method for deriving their classification on the basis of test results for individual elements.

This part of this European Standard currently cannot be applied to classify curtain walling for resistance to fire. Classification on the basis of extended application is outside the scope of this standard. For extended application, however, the same classes are used as specified in this standard. This standard deals with: a) Loadbearing elements without a fire separating function walls floors roofs beams columns balconies walkways stairs b) Loadbearing elements with a fire separating function, with or without glazing, services and fixtures walls floors roofs raised floors c) Products and systems for protecting elements or parts of the works ceilings with no independent fire resistance fire protective coatings, claddings and screens d) Non-loadbearing elements or parts of works, with or without glazing, services and fixtures partitions facades (curtain walls) and external walls ceilings with independent fire resistance fire doors and shutters and their closing devices smoke control doors conveyor systems and their closures penetration seals linear joint seals service ducts and shafts chimneys e) Wall and ceiling coverings with fire protection ability f) Lift landing doors which are tested to prEN 81-8 are excluded from this standard. Lift landing doors which are tested to EN 1634-1 are classified in accordance with 7.5.5. Relevant test methods which have been prepared for these elements are listed in clause 2. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text, and the publications are listed below.
