EN 2825:2011

Aerospace series - Burning behaviour of non metallic materials under the influence of radiating heat and flames - Determination of smoke density

This European Standard defines a test method for determination of the smoke density due to pyrolitic decomposition of solid materials and composite materials of up to 25 mm in thickness under the influence of radiant heat only or with simultaneous flame application.
The test results enable a comparison of the smoke production of different materials or material configurations under the conditions specified in this standard.
NOTE 1   The smoke gas density is determined according to the specific environmental and test conditions defined in EN 2824 and this standard. No studies have been made up to now to determine whether the results can be transferred to differing conditions, particularly to actual fire conditions.
NOTE 2   The burning behaviour - and consequently the smoke density - of aerospace materials are not only influenced by the type of material but also to a large extent by the configuration, the specific surface and mass, the combination with other materials, the means of joining as well as the processing technique.

Luft- und Raumfahrt - Brandverhalten nichtmetallischer Werkstoffe unter Einwirkung von strahlender Wärme und Flammen - Bestimmung der Rauchdichte

Diese Norm legt ein Prüfverfahren zur Bestimmung der Rauchdichte durch pyrolytische Zersetzung von Feststoffen und Verbundmaterialien von bis zu 25 mm Dicke unter der Einwirkung von Wärmestrahlung allein oder bei gleichzeitiger Flammeinwirkung fest.
Die Prüfergebnisse ermöglichen einen Vergleich der Rauchentwicklung verschiedener Materialien oder Materialkonfigurationen unter den in dieser Norm festgelegten Bedingungen.
ANMERKUNG 1   Die Rauchgasdichte wird gemäß den in EN 2824 und dieser Norm festgelegten, spezifischen Umgebungs- und Prüfbedingungen bestimmt. Bisher liegen keine Untersuchungen dazu vor, ob sich die Ergebnisse auf andere Bedingungen übertragen lassen, insbesondere auf den tatsächlichen Brandfall.
ANMERKUNG 2   Das Brandverhalten – und folglich die Rauchdichte – von Werkstoffen in der Luft- und Raumfahrt werden nicht allein durch den Werkstofftyp bestimmt, sondern in hohem Maße auch durch die Konfiguration, die spezifische Oberfläche und Masse, die Kombination mit anderen Werkstoffen, das Fügeverfahren sowie die Verarbeitungsmethode.

Série aérospatiale - Comportement au feu des matériaux non métalliques sous l'action de chaleur rayonnante et de flammes - Détermination de la densité de fumée

Aeronavtika - Gorljivost nekovinskih materialov zaradi žarčenja toplote in plamena - Ugotavljanje gostote dima

Ta evropski standard opredeljuje preskusno metodo za ugotavljanje gostote dima zaradi pirolitske razgradnje trdnih materialov in kompozitnih materialov debeline do 25 mm samo pod vplivom žarčenja toplote ali s hkratno uporabo ognja. Preskusni rezultati omogočajo primerjavo proizvodnje dima iz različnih materialov ali konfiguracij materialov pod pogoji, določenimi v tem standardu.
