associated with fire need to be considered I n this respect the objective of component, circuit and equipment design as well as the choice of materials is to reduce to a tolerable level of risk of fire even in the event of reasonably foreseeable (mis)use, malfunction or failure Fires involving electrotechnical products can also be initiated from external non-electrical sources Considerations of this nature are dealt with in the overall fire hazard assessment The aim of the I EC 60695 series of standards is to save lives and property by reducing the number of fires or reducing the consequences of the fire This can be accomplished by: – trying to prevent ignition caused by an electrically energised component part and, in the event of ignition, to confine any resulting fire within the bounds of the enclosure of the electrotechnical product – trying to minimise flame spread beyond the product’s enclosure and to minimise the harmful effects of fire effluents including heat, smoke, and toxic or corrosive combustion products This part of I EC 60695 describes a test method which consists of two small-scale fire test procedures carried out on materials used in electrotechnical equipment A 500 W test flame is used as an ignition source The test method described provides classifications which may be used for quality assurance, the pre-selection of component materials of products, or to verify the required minimum flammability classification of materials used in end products This test method should not be used to solely describe or appraise the fire hazard or fire risk of materials, products, or assemblies under actual fire conditions However, results of this test may be used as elements of a fire hazard assessment which takes into account all of the factors which are pertinent to a particular end use This international standard may involve hazardous materials, operations, and equipment I t does not purport to address all of the safety problems associated with its use I t is the responsibility of the user of this international standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use –8– I EC 60695-1 -20: 201 © I EC 201 F I RE H AZ ARD T E S T I N G – P a rt 1 - : T e s t fl a m e s – 0 W fl a m e t e s t m e t h o d Scope This part of I EC 60695 describes a test method consisting of two small-scale laboratory test procedures which is intended to compare the burning behaviour of different materials used in electrotechnical products Vertically oriented bar specimens or horizontally oriented plate test specimens are exposed to a small flame ignition source with a nominal thermal power of 500 W The test method uses two test specimen configurations to classify material performance Rectangular bar-shaped test specimens are used to assess ignitability and burning behaviour, and square plate test specimens are used to assess the resistance of the test specimen to burn-through, as defined in 3 This test method only applies to materials that have been classified as V-0 or V-1 according to I EC 60695-1 -1 This test method is only applicable to solid and cellular materials that have an apparent density of more than 250 kg/m , determined in accordance with I SO 845 The method does not apply to materials that shrink away from the applied flame without igniting due to their thinness The test method described provides classifications which may be used for quality assurance, the pre-selection of component materials of products, or to verify the required minimum flammability classification of materials used in end products I f used for pre-selection, then positive results shall be obtained at a test specimen thickness which equals the smallest thickness used in the product application The results obtained provide some information about the behaviour of materials in service, but cannot by themselves assure safe performance in service N OTE Gu i dance on pre-selecti on is given i n I EC 60695-1 -30 [3] N OTE Test resu lts are influ enced by materi al add itives, e g pi gmen ts, fillers, and fi re retard ants, and properties

de l'essai la flamme de 500 W, l'éprouvette peut se déformer de manière dynamique par la chaleur générée par la flamme d'essai et l'éprouvette brûlée elle-même (voir Figure A.1 ) Par conséquent, il peut s'avérer difficile de déterminer quel est le coin le plus proche du brûleur Lorsque l'éprouvette se gondole, il peut être impossible d'appliquer la flamme sur le coin De plus, si l'éprouvette se déforme de manière importante, le point d'application de la flamme peut être éloigné de la partie fixée de l'éprouvette La présente Annexe spécifie le point d'application détaillé de la flamme dans tous ces cas A.2 Déformation en J ou torsadée Si l'éprouvette prend la forme d'un J ou se torsade, il peut arriver que les deux coins se trouvent la même distance du brûleur Dans ce cas, appliquer la flamme au point milieu entre les deux coins (voir Figure A 2) et maintenir cette application tant que l'un des coins ne devient pas le plus proche du brûleur A.3 Déformation par courbure Si l'éprouvette se gondole, appliquer la flamme d'essai au point le plus proche en bas de l'éprouvette (voir Figure A 3) A.4 Déformation importante Même si le point d'application de la flamme est éloigné de la partie fixée de l'éprouvette en raison d'une déformation importante, appliquer la flamme d'essai au coin le plus proche du brûleur (voir Figure A 4) I EC 60695-1 -20: 201 © I EC 201 – 59 – IEC
