Aerospace series - Standardized measurement methods for comfort and living space criteria for aircraft passenger seats

This European Standard specifies requirements and measurement methods for the assessment of passenger living space and comfort. Its aim is to improve the passenger comfort quality of aircraft cabins and provide measurement methods to compare cabin seat layouts and seats.

Luft- und Raumfahrt - Sandardisierte Meßmethoden für Komfort und Living Space Kriterien bei Passagiersitzen im Flugzeug

Série aérospatiale - Mesure standardisée du confort et de l'espace de vie des sièges passagers d'avion

Aeronavtika - Standardizirane metode za merjenje kriterija udobja in življenjskega prostora potniških sedežev v zračnih plovilih

Ta evropski standard določa zahteve in merilne metode za oceno
življenjskega prostora in udobja potnikov. Njegov namen je izboljšati kakovost letalskih kabin v povezavi z udobjem za potnike
ter podati merilne metode za primerjavo postavitve kabinskih sedežev in kakovosti sedežev.
