NOTE It is a product composed of one or more components, substantial and/or non-substantial 3.1.5 substantial component material that constitutes a significant part of a non-homogeneous product. A layer with a mass/unit area
≥ 1,0 kg/m2 or a thickness ≥ 1,0 mm is considered to be a substantial component 3.1.6 non-substantial component material that does not constitute a significant part of a non-homogeneous product. A layer with a mass/unit area < 1,0 kg/m2 and a thickness < 1,0 mm is considered to be a non-substantial component NOTE Two or more non-substantial layers that are adjacent to each other (i.e. with no substantial component(s) in between the layers) are regarded as one non-substantial component when they collectively comply with the requirements for a layer being a non-substantial component. 3.1.7 internal non-substantial component non-substantial component that is covered on both sides by at least one substantial component 3.1.8 external non-substantial component non-substantial component that is not covered on one side by a substantial component 3.1.9 flooring upper layer(s) of a floor, comprising any surface finish with or without an attached backing and with any accompanying underlay, interlayer and adhesives 3.1.10 linear pipe thermal insulation product length of insulation product designed to fit around pipes, with a maximum outer insulation diameter of 300 mm and not intended for use with cylindrical ducts 3.1.11 substrate product which is used immediately beneath the product about which information is required.
NOTE For flooring, it is the floor on which it is mounted or the material which represents this floor

NOTE It covers aspects such as its quantity, orientation, position in relation to other adjacent products, and its method of fixing 3.1.14 fire performance response of an item when exposed to a specific fire (EN ISO 13943) 3.1.15 reaction to fire response of a product in contributing by its own decomposition to a fire to which it is exposed, under specified conditions 3.1.16 fire scenario detailed description of conditions, including environmental, of one or more stages from before ignition to after completion of combustion at a specific location or in a real scale simulation (EN ISO 13943) 3.1.17 reference scenario hazard situation used as a reference for a given test method or classification system 3.1.18 fire situation stage in the development of a fire, characterised by the nature, severity and size of the thermal attack on the products involved 3.1.19 combustion exothermic reaction of a substance with an oxidizer (EN ISO 13943) NOTE Combustion generally emits effluent accompanied by flames and/or visible light. 3.1.20 heat of combustion thermal energy produced by combustion of unit of mass of a given substance (EN ISO 13943) NOTE It is expressed in joules per kilogram. 3.1.21 gross heat of combustion (PCS) heat of combustion of a substance when the combustion is complete and any produced water is entirely condensed under specified conditions (EN ISO 13943) 3.1.22 net heat of combustion (PCI) heat of combustion of a substance when the combustion is complete and any produced water is in the vapour state under specified conditions (EN ISO 13943) NOTE The net heat of combustion may be calculated from the gross heat of combustion.

NOTE Lateral flame spread is the furthest extent of travel of a sustained flame, as measured in the
EN 13823 test. 3.1.29 sustained flaming existence of flame on or over a surface for a minimum period of time (EN ISO 13943) NOTE The period of time required will vary across different standards, but it is usually of the order of 10 s. 3.1.30 fully developed fire state of total involvement of combustible materials in a fire (EN ISO 13943) 3.1.31 flashover transition to a state of total surface involvement in a fire of combustible materials within an enclosure
(EN ISO 13943) 3.1.32 flaming droplets/particles material separating from the specimen during the fire test and continuing to flame for a minimum period as described by the test method 3.1.33 critical heat flux at extinguishment (CHF) incident heat flux (kW/m2) at the surface of a specimen at the point where the flame ceases to advance and may subsequently go out.
NOTE The heat flux value reported is based on interpolations of measurements with a non-combustible calibration board

NOTE It is the flux corresponding with the furthest extent of spread of flame within 30 min. 3.1.36 smoke hazard potential for injury and/or damage from smoke 3.1.37 FIGRA fire growth rate index used for classification purposes EXAMPLE: For the classes A2 and B, FIGRA = FIGRA0,2MJ For the classes C and D, FIGRA = FIGRA0,4MJ For the classes A2L, BL, and CL, FIGRA = FIGRA0,2MJ For the class DL, FIGRA = FIGRA0,4MJ 3.1.38 FIGRA0,2MJ maximum of the quotient of heat release rate from the specimen and the time of its occurrence using a THR-threshold of 0,2 MJ NOTE FIGRA0,2MJ is defined in more detail in EN 13823. 3.1.39 FIGRA0,4MJ maximum of the quotient of heat release rate from the specimen and the time of its occurrence using a THR threshold of 0,4 MJ NOTE The FIGRA0,4MJ is defined in more detail in EN 13823. 3.1.40 SMOGRA smoke growth rate. The maximum of the quotient of smoke production rate from the specimen and the time of its occurrence NOTE The SMOGRA is defined in more detail in EN 13823. 3.2 Symbols and abbreviations The symbols and notations correspond to those given in the appropriate test method. ∆T temperature rise [K] ∆m mass loss [%]

mean value of the set of results of a continuous parameter determined in accordance with the procedure in 7.3 and used for classification 4 Classes of reaction to fire performance The classes with their corresponding fire performance are given in:  Table 1 for construction products excluding floorings;  Table 2 for floorings;  Table 3 for linear pipe thermal insulation products. Products classified in a given class are deemed to satisfy all the requirements of any lower class. Pipe-insulation and insulation of cylindrical ducts with a maximum outer insulation diameter larger than 300 mm and insulation product intended to be used on flat surfaces shall be tested as prescribed in Table 1. A classification can only be obtained by undertaking the tests required for that particular product. A classification obtained for one product type, e.g. floorings, cannot be interpreted or accepted in a different classification system. 5 Test methods 5.1 General The following test methods are specified in relation to the envisaged reaction to fire classification. The relevant classification parameters are given in Tables 1, 2 and 3.
