— les essais d'étanchéité des installations ;
— le contenu du manuel d'utilisation.
Ce document ne s'applique qu’aux installations alimentées par des gaz appartenant à la troisième famille (GPL).
Elle ne couvre pas :
— les raccordements en eau ou en énergie électrique des appareils ;
— les appareils portatifs disposant d'une alimentation en gaz incorporée ;
— l'installation des appareils GPL utilisés pour les besoins commerciaux ;
— les installations GPL dans les bateaux ;
— l'équipement d'alimentation en GPL et les appareils GPL séparés et extérieurs au corps du véhicule.
Ce document couvre les réservoirs GPL qui satisfont aux exigences de la Directive Équipements sous Pression (2014/68/UE).
L’attention est portée sur la Directive Équipements sous pression (2014/68/UE) pour toute partie de l’installation fonctionnant au-delà de 0,5 bar.
Specifikacija za vgradnjo sistemov na utekočinjeni naftni plin (UNP) v bivalna vozila za prosti čas in druga bivalna vozila
Ta evropski standard določa zahteve za vgradnjo sistemov na utekočinjeni naftni plin v bivalna vozila za prosti čas in druga bivalna vozila. Podrobno določa varnostne in zdravstvene zahteve za izbiro materialov, komponent in aparatov, izdelavo in preskušanje trdnosti vgradenj ter vsebino uporabniškega priročnika.
Ta evropski standard ne zajema vgradenj, ki ne uporabljajo plinov tretje družine (LPG), vodovodnih priključkov ali električnega napajanja aparatov. Prenosni aparati z lastno oskrbo s plinom niso obravnavani kot del vgradnje in ne spadajo na področje uporabe tega standarda. Standard ne vključuje vgradnje aparatov na utekočinjeni naftni plin za komercialne namene ali plovila. Ta standard prav tako ne obravnava opreme za dovajanje plina in aparatov na plin, ki so ločeni od karoserije vozila in nameščeni zunaj nje.
