Furniture - Assessment of the ignitability of upholstered furniture - Part 1: Ignition source smouldering cigarette

This European Standard specifies a test method to assess the ignitability of material combinations, such as covers and fillings used in upholstered seating, when subjected to a smouldering cigarette as an ignition source.
The test measures only the ignitability of a combination of materials used in upholstered seating and not the ignitability of a particular finished item of furniture incorporating these materials.

Möbel - Bewertung der Entzündbarkeit von Polstermöbeln - Teil 1: Glimmende Zigarette als Zündquelle

Diese Europäische Norm legt ein Prüfverfahren zur Bestimmung der Entzündbarkeit von Werkstoff-kombinationen wie Bezüge und Füllungen für gepolsterte Sitzmöbel fest, wenn diese einer glimmenden Zigarette als Zündquelle ausgesetzt sind.
Anhand der Prüfungen wird lediglich die Entzündbarkeit einer Kombination von Werkstoffen bestimmt, die zur Herstellung von gepolsterten Sitzmöbeln verwendet wird, nicht aber die Entzündbarkeit eines bestimmten fertigen Möbelstücks, das aus diesen Werkstoffen besteht.

Ameublement - Évaluation de l’allumabilité des meubles rembourrés - Partie 1 : Source d’allumage : cigarette en combustion

La présente Norme européenne décrit une méthode d’essai destinée à évaluer l’allumabilité de combinaisons de matériaux, comme des revêtements et des rembourrages de sièges, lorsque la source d’allumage à laquelle ils sont exposés est une cigarette en combustion.
Cet essai mesure uniquement l’allumabilité d’une combinaison de matériaux utilisés dans les sièges rembourrés et non l’allumabilité d’un article d’ameublement fini particulier qui incorpore ces matériaux.

Pohištvo - Ocenjevanje vžigljivosti oblazinjenega pohištva - 1. del: Vir vžiga: tleča cigareta

Standard EN 1021-1 določa preskusno metodo za ocenjevanje vžigljivosti kombinacij materialov, kot so prevleke in polnila, ki se uporabljajo v oblazinjenih sedežih, kadar so podvrženi tleči cigareti kot viru vžiga. Preskus meri le vžigljivost kombinacije materialov, ki se uporabljajo v oblazinjenih sedežih, in ne tudi vžigljivosti posameznega dokončanega kosa pohištva, ki vključuje te materiale.

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 1021-1:2006. The main changes in relation to the 2006 edition of EN 1021-1 are: — Modification to the specification of the weight of the ignition source; — Modification to the test procedure to allow for a third ignition source to be placed on the test sample if either of the two initial ignition sources self extinguish prior to the completion of the test. According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. SIST EN 1021-1:2014

EN 1021-1:2014 (E) 4 Introduction This European Standard is one of a series of standards concerned with the ignitability of upholstered furniture using different ignition sources. The ignition source used in this European Standard is a smouldering cigarette. SIST EN 1021-1:2014

EN 1021-1:2014 (E) 5 1 Scope This European Standard specifies a test method to assess the ignitability of material combinations, such as covers and fillings used in upholstered seating, when subjected to a smouldering cigarette as an ignition source. The test measures only the ignitability of a combination of materials used in upholstered seating and not the ignitability of a particular finished item of furniture incorporating these materials. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 progressive smouldering exothermic oxidation, not accompanied by flaming, that is self-propagating, i.e. independent of the ignition source. It may or may not be accompanied by incandescence 2.2 flaming undergoing combustion in the gaseous phase with the emission of light 2.3 flammability ability of a material or product to burn with a flame under specified test conditions 2.4 ignitability measure of the ease with which a material, product or component can be ignited so as to flame or progressively smoulder 2.5 ignition source source of energy used to ignite combustible materials or products 2.6 outer cover outer layer of the upholstery 2.7 inner cover layer of material used between the outer cover and the upholstery filling whose nominal thickness is less than or equal to 2 mm Note 1 to entry: Any inner cover nominally greater than 2 mm thick is considered an upholstery filling. 2.8 filling main upholstery material contained by the outer cover and (if used) the inner cover which may consist of several different materials, including any inner cover nominally greater than 2 mm thick 3 Criteria of ignition 3.1 Progressive smouldering ignition For the purposes of this European Standard, all the following types of behaviour are considered to be progressive smouldering ignitions: SIST EN 1021-1:2014

EN 1021-1:2014 (E) 6 a) any test assembly that displays escalating combustion behaviour so that it is unsafe to continue the test and active extinction is necessary; b) any test assembly that smoulders until it is largely consumed within the test duration; c) any test assembly that smoulders to the extremities of the specimen, viz. upper or lower margins, either side or to its full thickness, within the duration of the test; d) any test assembly that smoulders after one hour from the application of the ignition source; e) any test assembly that, on final examination (see 9.3), shows evidence of progressive smouldering. NOTE In practice it has been found that there is usually a clear distinction between materials which may char under the influence of the ignition source but which do not propagate further (non-progressive combustion) and those where smouldering develops in extent and spreads (progressive combustion). 3.2 Flaming ignition For the purposes of this European Standard, a flaming ignition is considered to be the occurrence of any flames initiated by a smouldering source. 4 Principle To subject an assembly of upholstery materials to a smouldering ignition source. The assembly is arranged to represent in stylised form a junction between a seat and back (or seat and arm) such as might occur in a typical chair. The ignitability of an assembly is determined by applying a smouldering ignition source such as a cigarette. The test method measures the ignitability of the overall composite of materials, i.e. outer cover, inner cover, filling etc., as constructed on the test rig. The tests give an indication of, but cannot guarantee, the ignition behaviour of the finished item of furniture. The results shall not be stated as being applicable to the general behaviour of any individual component (see also Annex A). NOTE Test specimens prepared from materials taken from furniture that has been used may give different results to the same materials before use. 5 Health and safety of operators 5.1 General The test method specified in this European Standard presents a considerable hazard; suitable precautions shall be taken. 5.2 Enclosure For safety, the test should be conducted in a non-combustible fume cupboard. If such a cupboard is not available, a test enclosure should be constructed (see 6.2) so that the operator is protected from the fumes. 5.3 Extinguishers Adequate means of extinguishing the assembly should be provided bearing in mind that some combinations may produce severe flaming during the test. A hand and/or fixed water spray which can be directed over the burning area can be useful. Other means such as suitable fire extinguishers, fire blankets and a bucket of water will assist. In some cases smouldering may be difficult to extinguish completely and complete immersion in water may be necessary. SIST EN 1021-1:2014

EN 1021-1:2014 (E) 7 6 Apparatus 6.1 Test rig A suitable test rig is illustrated in Figures 1 and 2. It shall consist of two rectangular frames hinged together and capable of being locked at right angles to each other. The sides and hinge edges of the frames shall be made from nominal 25 mm x 3 mm steel flat bar and shall securely hold mesh steel platforms set (6 ± 1) mm below the top edge of the frames. (Mesh size should be such that an open mesh area of approximately 15 mm2 to 150 mm2 exists). The upper edge of the vertical frame and the front edge of the horizontal frame shall be steel end plates

450 mm x 65 mm x 3 mm to prevent the test filling moving during the assembly of the test specimen (see Figures 1 and 2). The internal width and height of the back frame shall be (450 ± 2) mm x (300 ± 2) mm and the width and depth of the base frame (450 ± 2) mm x (150 ± 2) mm. A standard edging section may be used around the mesh steel platform to give protection and greater rigidity. The sides of the frame shall extend beyond the back of each frame to provide for the hinge holes and to form the back legs. The hinge rod shall be of nominal 10 mm diameter steel, continuous across the back of the rig and its axis (22,5 ± 0,5) mm beyond the back member of each frame. The frames shall be lockable at right angles by a bolt or pin through each of the pairs of members forming the back legs. The front legs may be welded across the front corners of the base frame. The height of the legs shall be such as to leave a gap not less than 50 mm high between the base and frame and the supporting surface. For the tests the rigs shall be sited within the enclosure (see 6.2) and the testing shall be performed in a basically draught-free environment permitting an adequate supply of air and removal of smoke from the area of the apparatus.

(68 ± 2) mm; — diameter: (8 ± 0,5) mm; — mass:

(0,85 ± 0,15) g. The smouldering rate shall be (7,5 ± 2) min/40 mm, when tested as follows. Mark the cigarette, conditioned as described in 7.2 at 10 mm and 50 mm from the end to be lit. Light it as described in 9.2.1 and impale it horizontally in air (air speed rate less than 0,2 m/s) on a horizontal wire spike inserted not more than 13 mm into the unlit end. Record the time taken to smoulder from the 10 mm to the 50 mm mark. The smouldering rate shall be measured on one cigarette from a batch of 20 cigarettes. The smouldering rate may be measured on two cigarettes at the same time. The distance between cigarettes and between each cigarette and any nearby surface such as the wall or floor of the test enclosure shall be at least 150 mm. If the cigarette ceases smouldering before reaching the 50 mm mark, the measurement of smouldering rate shall be repeated. 7 Preparation and conditioning 7.1 Preparation All outer covers and inner covers that have been chemically treated to reduce their ignitability shall be subjected to the water soaking and drying procedure described in Annex D prior to being conditioned according to 7.2. This requirement applies to all methods of treatment, including back coating, which are applied to material covers that are finished in all other respects. It does not apply when the cover material is manufactured from materials that are formulated to be, or are inherently, flame retardant (e.g. fabric woven from inherently flame retardant yarns, PVC) provided it is not further treated as a finished cover material. Where it is not known whether the material has
