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

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

Dieses Dokument legt das Prüfverfahren zur Bestimmung der senkrechten Flammenausbreitung und der Nachbrennzeit nichtmetallischer Werkstoffe im Ganzen oder teilweise fest.
Dieses Prüfverfahren wird ebenfalls zur Prüfung nichtmetallischer Werkstoffe verwendet, die die Prüf-kriterien für die Bunsenbrennerprüfung (senkrecht) erfüllen müssen:
a) bei einer Beflammungszeit von 60 s;
b) 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 auch in anderen Anwendungen verwendet werden können, wie in geltenden Dokumenten zu Auftragsvergabe und Rechtsvorschriften festgelegt.
Diese Norm sollte zur Messung und Beschreibung der Eigenschaften nichtmetallischer Werkstoffe, Erzeug-nisse oder Baugruppen angewendet werden, die unter kontrollierten Laborbedingungen Wärme und Beflammung ausgesetzt sind; sie sollte nicht für die Beschreibung oder Bewertung der Brandgefahr oder des Brandrisikos von Werkstoffen, Erzeugnissen oder Baugruppen bei realen Brandsituationen angewendet werden. Die Prüfergebnisse dürfen jedoch 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

Le présent document spécifie la méthode d’essai pour la détermination de la propagation verticale de la flamme et de la durée de flamme résiduelle de tout ou partie des matériaux non métalliques.
Cette méthode d’essai est aussi utilisée pour tester les matériaux non métalliques qui doivent satisfaire aux critères d’essai relatifs à l’essai au brûleur de Bunsen, vertical :
a)   avec une durée d’application de la flamme de 60 s ;
b)   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 aussi 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 dokument določa preskusno metodo za ugotavljanje navpičnega širjenja ognja in časa gorenja po odstranitvi vira vžiga nekovinskih materialov deloma ali v celoti. Ta preskusna metoda se uporablja tudi za preskušanje nekovinskih materialov, ki morajo ustrezati preskusnim merilom za navpični preskus Bunsenovih gorilnikov: a) s časom uporabe plamena 60 s; b) s časom uporabe plamena 12 s. Uporablja se za vrednotenje nekovinskih materialov ali konstrukcij, ki se uporabljajo v notranjosti aeronavtičnih plovil, uporaba pa je mogoča tudi na drugih področjih uporabe, kot je določeno v veljavnih dokumentih za dobavo in v zakonskih dokumentih. Ta standard se predvidoma uporablja za merjenje in opis lastnosti nekovinskih materialov, proizvodov ali sklopov v odzivu na toploto in ogenj v nadzorovanih laboratorijskih pogojih in se ne uporablja za opis ali oceno požarne nevarnosti ali požarnega tveganja materialov, proizvodov ali sklopov v dejanskih požarnih razmerah. Kljub temu je mogoče rezultate tega preskusa uporabiti kot elemente ocene požarnega tveganja, ki upošteva vse dejavnike, ki se navezujejo na oceno nevarnosti posamezne končne uporabe.

1 Scope

This document specifies the test method for the determination of the vertical flame propagation and

after flame time of non-metallic materials in part or in whole.

This test method is also used for testing non-metallic materials which have to meet the test criteria for

the vertical Bunsen burner test:
a) with a flame application time of 60 s;
b) 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 also 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.
