BS EN 13501-3:2005+A1:2009EN 13501-3:2005+A1:2009 (E) 4 Introduction The aim of this European Standard is to de

26、fine a harmonised 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 European Standard is prepared in support of the second essen

27、tial requirement in the EC Construction Products Directive (89/106/CEC), 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

28、 classification of the resistance to fire performance of construction products, construction works and parts thereof. The Interpretative Document and the Commission Decision of 3 May 2000 specify performance and classes regarding fire resistance. These classes are identified by designation letters,

29、each of which refers to an important characteristic of fire resistance behaviour. This European Standard 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 derivi

30、ng 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 prEN 15725. BS EN 13501-3:2005+A1:2009EN 13501-3:2005+A1:2009 (E) 5 1 Scope This Europ

31、ean Standard 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 te

32、st method. !Classification on the basis of extended application of test results is also included in the scope of this European Standard.“ Products/elements for use in ventilation systems include (excluding smoke and heat exhaust ventilation): fire resisting ducts; fire dampers. Relevant test methods

33、 which have been prepared for these products/elements are listed in Clause 2. 2 Normative references The following referenced documents are indispensable for the application of this European Standard. For dated references, only the edition cited applies. For undated references, the latest edition of

34、 the referenced document (including any amendments) applies.

36、 (involving the application of defined rules) whereby a test result is deemed to be equally valid for variations in one or more of the product properties and/or intended end use applications 3.2 extended field of application the outcome of a process (involving the application of defined rules that m

37、ay incorporate calculation procedures) that predicts, for a variation of a product property and/or its intended end use application(s), a test result on the basis of one or more test results to the same test standard 3.3 test specimen element (or part) of building construction provided for the purpo

NOTE Other heating curves may exist: sm

42、ouldering fire test is only used if the fire resistance performance of the product/element is expected to be reduced by exposure to temperatures associated with the growth stage of a fire. It is, therefore, particularly relevant to products/elements whose performance may be dependent upon high heati

43、ng rates below approximately 500 C (as provided during the standard temperature/time curve) for achievement of their classifications (i.e. mainly reactive or intumescent products). Further details relating to the practical application of this curve, and other test parameters, e.g. tolerances, are gi

44、ven in EN 1363-2; hydrocarbon curve is another example; also for extreme fire scenarios (e.g. traffic tunnels and nuclear plants), more severe conventional curves may be specified. These are not, however, used for the classification of elements according to this European Standard. 4.2 The standard t

45、emperature/time curve (post flashover fire) When applied as a basis for testing, the standard temperature/time relationship shall be applied for the full duration of the test. The relationship, which is a model of a fully developed fire in a compartment, is given by the following relationship: T = 3

46、45 log10(8t + 1) + 20 (1) BS EN 13501-3:2005+A1:2009EN 13501-3:2005+A1:2009 (E) 7 where t is the time from the start of the test in minutes, and T is the mean furnace temperature in C.

48、to prevent the transmission of fire as a result of the passage of significant quantities of flames or hot gases from the fire to the unexposed side, thereby causing ignition either of the non-fire exposed surface or of any material adjacent to that surface. The assessment of integrity is made on the

49、 basis of one or more of the following aspects simultaneously: cracks or openings in excess of given dimensions; ignition of a cotton pad; sustained flaming on the unexposed side; leakage in excess of given values. The integrity shall be determined by all methods during the test. The cotton pad procedure shall be applied until the pad ignites and, once it has ignited, it shall
