Aerospace series - Paints and varnishes - Two component cold curing polyurethane finish - Supersonic erosion resistance
This standard specifies the requirements for a two component polyurethane, topcoat, with a medium degree of resistance to erosion by the effects of rain, available in a range of colours and levels of gloss, to be applied over a primer for aerospace applications on areas where rain erosion at supersonic speeds may be a problem e.g. leading edges and air intakes. The properties specified in this standard are obtained on defined aluminium alloy test pieces prepared in accordance with EN 3837 Procedure A and EN 23270 and painted with primer to EN 2435. The ability of the material to be used for a specific application (e.g. alternative substrate, alternative primer, specific drying conditions etc.) shall be determined by supplementary tests to confirm that the requirements of this standard are met.
Luft- und Raumfahrt - Anstrichstoff - Zweikomponenten Polyurethan-Decklack, raumtemperaturhärtend - Überschall-Erosionsbeständigkeit
Diese Norm legt die Anforderungen an einen Zweikomponenten-Polyurethan-Decklack mit mittlerer Beständigkeit gegenüber regenbedingter Erosion fest, den es mit einer Auswahl an Farbtönen und Glanzstufen gibt. Er wird auf eine Grundbeschichtung für Luft- und Raumfahrtanwendungen in Zonen, in denen Regenerosion bei Unterschallgeschwindigkeiten ein Problem darstellen kann, wie beispielsweise am Keilwinkel oder an Lufteintritten, aufgebracht.
Die in dieser Norm festgelegten Eigenschaften beziehen sich auf definierte Probenkörper aus einer Aluminiumlegierung, die nach EN 3837 Verfahren A und EN 23270 vorbereitet und mit einem Grundbeschichtungsstoff nach EN 2435 beschichtet werden. Die Tauglichkeit eines Werkstoffes für eine spezifische Anwendung (z. B. alternativer Untergrund, alternativer Grundbeschichtungsstoff, spezifische Trocknungsbedingungen usw.) muss durch zusätzliche Prüfungen festgestellt werden, die bestätigen, dass die Anforderungen dieser Norm erfüllt sind.
Série aérospatiale - Peintures et vernis - Deux composants durcissement à froid, finition polyuréthane - Résistance à l’érosion supersonique
La présente Norme européenne spécifie les exigences d’une couche de finition polyuréthane, à deux composants, degré moyen de résistance à l’érosion due aux effets de la pluie, disponible dans une gamme de couleurs et de niveaux de brillance, applicable sur une peinture primaire pour applications aérospatiales sur des zones où l’érosion par la pluie à des vitesses supersoniques peut constituer un problème par ex. bord d’attaque et entrées d’air.
Les propriétés spécifiées dans la présente norme sont obtenues sur des éprouvettes en alliage d’aluminium définies conformément à l’EN 3837 Procédure A et l’EN 23270 et peintes avec un primaire selon l’EN 2435. L’aptitude du matériau à être utilisé pour une application spécifique (par ex. subjectile alternatif, primaire alternative, conditions de séchage spécifiques, etc.) doit être déterminée par des essais complémentaires pour confirmer que les exigences de la présente norme sont satisfaites.
