NOTE   Les exigences des règlements RID/ADR prévalent sur les dispositions de la présente norme dans le cas de bouteilles conformes à ces règlements, y compris les bouteilles comportant un marquage pi.
La présente Norme européenne ne s'applique pas aux bouteilles installées en permanence dans des véhicules.

Oprema in pribor za utekočinjeni naftni plin (UNP) - Premične, ponovno polnljive jeklenke za UNP, ki niso varjene in trdo spajkane - Periodična kontrola (vključno z dopolnilom A2)

Ta evropski standard določa postopke za periodično kontrolo in preskušanje premičnih, ponovno polnljivih jeklenk za utekočinjeni naftni plin (LPG) z vodno kapaciteto od 0,5 l do vključno 150 l.
Ta evropski standard se uporablja za:
– varjene jeklenke za utekočinjeni naftni plin z alternativno zasnovo in konstrukcijo (glej standard EN 14140 ali enakovreden standard);
– varjene aluminijaste jeklenke za utekočinjeni naftni plin (glej standard EN 13110 ali enakovredni standard);
– kompozitne jeklenke za utekočinjeni naftni plin (glej standard EN 14427 ali enakovredni standard);
– prelite jeklenke, zasnovane in izdelane v skladu s standardom EN 1442 ali EN 14140 (glej dodatek F).
OPOMBA:   V primeru jeklenk, ki izpolnjujejo te predpise (vključno z jeklenkami z oznako pi), imajo pred zahtevami tega standarda prednost zahteve RID/ADR.
Ta evropski standard se ne uporablja za jeklenke, trajno nameščene v vozila.
