Aerospace series - Flammability of non metallic materials - Part 2: Small burner test, horizontal - Determination of the horizontal flame propagation
This standard specifies the test method for the determination of the horizontal flame propagation of non metallic materials when subjected to a small flame.
This test method is also used for testing non metallic materials which have to meet the test criteria for the horizontal Bunsen burner test.
It is used for evaluation of non metallic materials or constructions used in the interiors of aerospace vehicles but may be used in other applications as specified in applicable procurement and regulatory documents.
This standard should be used to measure and describe the properties of non metallic materials, products or assemblies in response to heat and flame under controlled laboratory conditions and should not be used to 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 risk assessment which takes into account all of the factors which are pertinent to an assessment of the fire hazard of a particular end use.

Série aérospatiale - Inflammabilité des matériaux non métalliques - Partie 2: Essai au brûleur, horizontal - Détermination de la propagation horizontale de la flamme
Cette Norme européenne spécifie la méthode d’essai pour la détermination de la propagation horizontale de la flamme des matériaux non métalliques lorsqu’ils sont soumis à une petite flamme.
Cette méthode d’essai est aussi utilisée pour tester les matériaux non métalliques qui doivent satisfaire les critères d’essai relatifs à l’essai au brûleur de Bunsen, horizontal.
Elle est utilisée pour évaluer les matériaux et les constructions non métalliques utilisés à l’intérieur des véhicules aérospatiaux mais elle peut être utilisée dans d’autres applications comme spécifié dans les documents d’approvisionnement et réglementaires applicables.
Il convient d’utiliser la présente norme pour mesurer et décrire les propriétés des matériaux, produits ou ensembles non métalliques en réponse à la chaleur et à la flamme dans des conditions contrôlées de laboratoire et non pas pour décrire ou évaluer les dangers ou les risques d’incendie des matériaux, produits ou ensembles dans des conditions réelles d'incendie. Toutefois, les résultats de cet essai peuvent être utilisés en tant qu’éléments d’évaluation des risques d’incendie qui tiennent compte de tous les facteurs pertinents pour faire une évaluation des dangers d’incendie liés à utilisation finale particulière.
Aeronavtika - Vnetljivost nekovinskih materialov - 2. del: Preskus majhnih gorilnikov, vodoravni - Ugotavljanje vodoravnega širjenja ognja
Ta evropski standard določa preskusno metodo za ugotavljanje vodoravnega širjenja ognja nekovinskih materialov, ki so izpostavljeni majhnemu ognju. Ta preskusna metoda se uporablja tudi za preskušanje nekovinskih materialov, ki morajo ustrezati preskusnim merilom za vodoravni preskus Bunsenovih gorilnikov. Uporablja se za vrednotenje nekovinskih materialov ali struktur, ki se uporabljajo v notranjosti aeronavtičnih plovil, lahko pa se uporablja tudi pri drugih aplikacijah, kot je določeno v veljavnih dokumentih za dobavo in zakonskih dokumentih. Ta standard se mora uporabljati za merjenje in opis lastnosti nekovinskih materialov, proizvodov ali sklopov kot odziv na toploto in ogenj v nadzorovanih laboratorijskih pogojih in se ne sme uporabljati za opis ali oceno požarne nevarnosti ali požarnega tveganja materialov, proizvodov ali sklopov v dejanskih požarnih razmerah. Rezultati tega preskusa pa se lahko uporabijo kot elementi ocene požarnega tveganja, ki upošteva vse dejavnike, ki se nanašajo na oceno požarne nevarnosti pri določeni končni uporabi.

NOTE In this test, it is the speed with which a flame front moves across a test specimen mounted horizontally. 3.2 time of flame application length of time the burner flame is applied to the specimen 3.2 burn length distance in millimetres from the original specimen edge to the farthest evidence of damage of the test specimen due to that area's combustion, including areas of partial consumption, charring, or embrittlement, but not including areas sooted, stained, warped or discoloured, nor areas where material has shrunk or melted away from the heat 4 Principle of method Testing is performed on a specimen that is held horizontal. A burner flame, having defined parameters, is applied to the specimen for a defined period of time. The after flame time and the burn length is measured. The occurrence of drips and their afte
