Aerospace series - Flammability of non metallic materials - Part 1: Small burner test, vertical - Determination of the vertical flame propagation

This standard specifies the test method for the determination of the vertical flame propagation and after flame time of non metallic materials.
This test method is also used for testing non metallic materials which have to meet the test criteria for the vertical Bunsen burner test:
-   with a flame application time of 60 s;
-   with a flame application time of 12 s.
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.

Luft- und Raumfahrt - Entflammbarkeit nichtmetallischer Werkstoffe - Teil 1: Kleinbrenner-Prüfung, senkrecht - Bestimmung der senkrechten Flammenausbreitung

Diese Europäische Norm legt das Prüfverfahren zur Bestimmung der senkrechten Flammenausbreitung und der Nachbrennzeit nichtmetallischer Werkstoffe fest.
Dieses Prüfverfahren wird ebenfalls zur Prüfung nichtmetallischer Werkstoffe verwendet, die die Prüfkriterien für die Bunsenbrennerprüfung (senkrecht) erfüllen müssen:
-   bei einer Beflammungszeit von 60 s;
-   bei einer Beflammungszeit von 12 s.
Es wird zur Bewertung nichtmetallischer Werkstoffe oder Konstruktionen verwendet, die im Inneren von Luft- und Raumfahrzeugen verwendet werden, aber in anderen Anwendungen verwendet werden können, wie in geltenden Dokumenten zu Auftragsvergabe und Rechtsvorschriften festgelegt.
Das vorliegende Dokument sollte zur Messung und Beschreibung der Eigenschaften nichtmetallischer Werkstoffe, Erzeugnisse oder Baugruppen angewendet werden, die unter kontrollierten Laborbedingungen Wärme und Beflammung ausgesetzt sind; sie sollte nicht für die Be¬schrei¬bung oder Bewertung der Brandgefahr oder des Brandrisikos von Werkstoffen, Erzeugnissen oder Bau¬gruppen bei realen Brandsituationen angewendet werden. Die Prüfergebnisse können jedoch möglicher¬weise als Elemente einer Bewertung des Brandrisikos verwendet werden, die alle Faktoren berücksichtigt, die eine Bewertung der Brandgefahr einer bestimmten Endanwendung nachhaltig beeinflussen.

Série aérospatiale - Inflammabilité des matériaux non métalliques - Partie 1: Essai au brûleur, vertical - Détermination de la propagation verticale de la flamme

Cette Norme européenne spécifie la méthode d’essai pour la détermination de la propagation verticale de la flamme et de la durée de flamme résiduelle des matériaux non métalliques.
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, vertical :
-   avec une durée d’application de la flamme de 60 s ;
-   avec une durée d’application de la flamme de 12 s.
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 une utilisation finale particulière.

Aeronavtika - Vnetljivost nekovinskih materialov - 1. del: Preskus majhnih gorilnikov, navpični - Ugotavljanje navpičnega širjenja ognja

Ta evropski standard določa preskusno metodo za ugotavljanje navpičnega širjenja ognja in časa gorenja po odstranitvi vira vžiga nekovinskih materialov. Ta preskusna metoda se uporablja tudi za preskušanje nekovinskih materialov, ki morajo ustrezati preskusnim merilom za navpični preskus Bunsenovih gorilnikov: - s časom uporabe plamena 60 s; - s časom uporabe plamena 12 s. 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.

3.4
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 vertical. 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 after flame time is measured.
