Aerospace Series - Commercial aircraft passenger seats - Reliability testing

Luft- und Raumfahrt - Fluggastsitze für die zivile Luftfahrt - Zuverlässigkeitstests

Série aérospatiale - Sièges passagers d’aéronefs commerciaux - Essais de fiabilité

Le présent document spécifie les exigences minimales des essais de fiabilité pour les sous-composants des sièges passagers des aéronefs commerciaux. Des procédures d'essai comprenant des cas de charge en service concernant le comportement des passagers pour les sous-composants de sièges sont définies. Les charges excessives sont exclues. Ce document est applicable aux sous-composants de sièges tels que, sans toutefois s'y limiter, le dossier, l’appuie-tête, les accoudoirs, la tablette, la pochette à documentation et les organes de commande.
Le présent document ne s’applique pas aux ceintures, systèmes de divertissement à bord, housses et rembourrages de siège.
D'autres éléments environnementaux tels que la température, les rayonnements, les gaz et les liquides peuvent également avoir un impact sur la fiabilité des sièges passagers d’aéronefs et de leurs sous-composants au cours de leur vie, mais ils ne sont pas pris en compte dans le présent document.
Des essais d'abrasion et de durabilité des surfaces sont définis dans l’EN 4860, l’EN 4864 et l’EN 4876.
