Le présent document :
— spécifie les exigences minimales relatives aux matériaux, à la conception, à la fabrication, aux essais de qualification de modèle et aux contrôles courants de production des bouteilles composites entièrement bobinées pour gaz de pétrole liquéfié (GPL), d'une capacité en eau comprise entre 0,5 l et 150 l inclus, exposées aux températures ambiantes, pour une pression d'essai d'au moins 30 bar ;
— s'applique uniquement aux bouteilles qui sont dotées d'une soupape de sécurité (voir 4.1.3) ;
— s'applique aux bouteilles munies d'un liner métallique (avec ou sans soudure) ou non métallique (ou constitué d'un mélange de ces matériaux), renforcé par des fibres de verre, de carbone ou d'aramide (ou un mélange de ces matériaux) ;
— s'applique également aux bouteilles composites sans liner.
Les bouteilles fabriquées selon le présent document sont adaptées à des températures pouvant descendre jusqu'à –40 °C.
Le présent document ne traite pas de la conception, du montage et des performances des enveloppes de protection amovibles. Lorsque celles-ci sont montées, il est attendu que le choix du matériau et les performances des enveloppes soient considérés séparément.
Oprema in pribor za utekočinjeni naftni plin (UNP) - Premične, ponovno polnljive jeklenke iz kompozitnih materialov za UNP - Konstruiranje in izdelava
Ta evropski standard:
– določa minimalne zahteve za materiale, konstruiranje, izdelavo, preskušanje prototipov in rutinske proizvodne inšpekcijske preglede popolnoma obvitih jeklenk iz kompozitnih materialov s prostornino vode od 0,5 l do vključno 150 l za utekočinjeni naftni plin (UNP), izpostavljene temperaturam okolja, s preskusnim tlakom vsaj 30 barov;
– se uporablja le za jeklenke, ki so opremljene z varnostnim ventilom (glej točko 4.1.3);
– se uporablja za jeklenke z oblogo iz kovinskega materiala (varjenega ali nevarjenega) ali nekovinskega materiala (ali njegove mešanice), okrepljene s steklenimi vlakni, ogljikovimi ali aramidnimi (ali njuno mešanico);
– se uporablja tudi za jeklenke iz kompozitnih materialov brez oblog.
Jeklenke, proizvedene v skladu s tem evropskim standardom, so primerne za temperature do –40 °C.
Ta evropski standard ne obravnava konstruiranja, nameščanja in lastnosti odstranljivih zaščitnih ovitkov. Kadar so zaščitni ovitki nameščeni, naj bi se izbira materiala in lastnosti ovitkov obravnavale ločeno.
