SIST EN 13501-4:2016



EN 13501-4:2016(E) 5 Introduction This European Standard defines a harmonized procedure for the classification for resistance to fire of construction products. This classification is based on the test procedures sited in the relevant documents listed in Clause 2 and the relevant field of application procedures. This European Standard is prepared in support of the second basic requirement, in the EC Construction Products Regulation ( 305/2011) and is detailed in the Interpretative Document number 2 (ID2): Safety in case of fire (OJC62 Vol 37). 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, 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/elements and explains the method for deriving their classification on the basis of test results and/or extended application results for individual products/elements. NOTE Test reports constitute the basis for extended application reports as explained in EN 15725. SIST EN 13501-4:2016



EN 13501-4:2016 (E) 6 1 Scope This European Standard specifies the procedure for classification of components of smoke control systems, using data from fire resistance tests which are within the field of application of the relevant test methods. Classification on the basis of extended application of test results is also included in the scope of this European Standard. Products covered by this European Standard are: — smoke control ducts; — smoke control dampers; — smoke barriers; — powered smoke and heat control ventilators (fans), including connectors; — natural smoke and heat exhaust ventilators. Relevant documents which include the relevant test methods which have been prepared for these products are listed in Clause 2. 2 Normative references The following documents, in whole, or in part, are normatively referenced in this document and are indispensable for its application.

To demonstrate satisfaction of this requirement, the fire resistance performance of these components is addressed in this European Standard. Fire resistance shall be assessed using one or more of the levels of thermal attack given in 4.2 to 4.5. NOTE 2 Later clauses of this European Standard identify which attack(s) shall be used for which products. NOTE 3 The various levels of thermal action given in 4.2 to 4.5 reflect different fire scenarios and the standards which specify their translation into practical tests give tolerances for their application. SIST EN 13501-4:2016



EN 13501-4:2016(E) 9 NOTE 4 Other heating curves exist, for example the hydrocarbon curve. Also, for extreme fire scenarios (e.g. traffic tunnels, nuclear plants), more severe conventional curves are specified. These are not, however, used for the classification of products according to this European Standard. 4.2 The standard temperature/time curve (post flash-over fire) The ‘post flash-over’ fire test utilizes the ‘standard temperature/time relationship’ which is a model of a fully developed fire in a compartment and is given by the following relationship: T = 345 log10 (8t + 1) + 20 where t is the time from the start of the test in minutes (min); T is the mean furnace temperature in degrees Celsius (°C). The post flash-over fire curve shall be applied in accordance with EN 1363-1. When applied as a basis for testing, the relationship shall be applied for the full duration of the test. 4.3 The slow heating curve (smouldering fire) The ‘smouldering’ fire test shall only used if the fire resistance performance of the product is expected to be reduced by exposure to temperatures associated with the growth stage of a fire. NOTE It is, therefore, particularly relevant to products whose performance can be dependent upon high heating rates below approximately 500 °C (defined in the ‘standard temperature/time’ curve) for achievement of their classifications (i.e. mainly reactive or intumescent products). The slow heating curve is given by the following relationship: for

where t is the time from start of test, in minutes (min); T is the mean furnace temperature in degrees Celsius (°C). The smouldering fire curve shall be applied in accordance with EN 1363-2. 4.4 Constant temperature attack In addition to the heating regimes given above, the evaluation of smoke barriers and smoke and heat exhaust ventilators shall be made using a notional constant temperature attack. The specified temperature and the rate at which the temperature is reached, is specified in the relevant test method. SIST EN 13501-4:2016

EN 13501-4:2016(E) 11 5 Resistance to fire performance characteristics 5.1 General NOTE 1 The basic requirement ‘safety in case of fire’ of the Construction Products Regulation requires the products covered in this standard to be assessed against specified characteristics. These include integrity, insulation, stability, smoke leakage and reliability. This clause provides the necessary details of each of the above characteristics. NOTE 2 Where a characteristic may have more than one different definition or type of performance, later clauses identify which specific definition applies to which products. 5.2 Performance characteristics 5.2.1 E – Integrity Integrity E is the ability of a component of a smoke control system 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 shall be made on the 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 non-exposed side; — leakage measurements; — maintenance cross section and mechanical stability. 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 be withdrawn and the test continued until all aspects have been exceeded (the sponsor has the option, however, of stopping the test once the desired level has been reached). The times of each mode of integrity failure shall be recorded. Classification of integrity is according to whether or not the component is also classified for insulation. Where a component is classified both for integrity E and insulation I, the integrity value shall be that determined by whichever of the four criteria fails first. Where a component is classified E but without an I classification, failure of the cotton pad shall not be taken into account. Where leakage rate is a performance characteristic for integrity, the limit value for different products is given in the relevant clause. Conformity to the requirements for criterion, E, is required for: — multi-compartment smoke control ducts; — single compartment smoke control ducts; — multi-compartment smoke control dampers; SIST EN 13501-4:2016



EN 13501-4:2016 (E) 12 — single compartment smoke control dampers. 5.2.2 I – Insulation Insulation I is the ability of a component of a service installation to withstand fire exposure without the transmission of fire as a result of significant transfer of heat. Heat transfer shall be limited so that non-exposed surfaces or any material in close proximity to that surface is not ignited. The product shall also provide a barrier to heat sufficient to protect people near to it. Conformity to the requirements for criterion, I, is required for: — multi-compartment smoke control ducts; — multi-compartment smoke control dampers. Conformity to the requirements for criterion, I is also required for powered smoke and heat ventilators outside the burning room inside the building. 5.2.3 S – Smoke leakage Smoke leakage S is the ability of a product to resist the passage of smoke under defined temperature and pressure conditions. Conformity to the requirements for criterion, S, is required for: — multi-compartment smoke control ducts; — single compartment smoke control ducts; — multi-compartment smoke control dampers; — single compartment smoke control dampers. 5.2.4 D – Stability duration under constant temperature Stability duration under constant temperature is the ability of a product to resist the passage of gasses or smoke under a constant temperature attack of 600 °C. It includes:
