LPG equipment and accessories - Pressure relief valves for LPG pressure vessels - Reconditioning requirements

This European Standard specifies the requirements for the reconditioning, retesting and certification of Pressure Relief Valves (PRVs) for LPG pressure vessels covered under the scope of EN 14129.
This European Standard applies to retesting and reconditioning of PRVs that are carried out in a workshop and does not apply to site adjustment of installed PRVs.
Annex A is an informative Annex detailing a sampling approach for PRV requalification which should only be used in case of on-site requalification of series produced pressure vessels fitted with series produced PRVs.

Flüssiggas-Geräte und Ausrüstungsteile - Sicherheitsventile für Druckbehälter für Flüssiggas (LPG) - Anforderungen an die Instandsetzung

Diese Europäische Norm legt die Anforderungen für die Instandsetzung, Wiederholungsprüfung und Zertifizierung von Sicherheitsventilen für Druckbehälter (PRV) für Flüssiggas (LPG) fest, die in den Anwendungsbereich der EN 14129 fallen.
Diese Europäische Norm gilt für Wiederholungsprüfungen und Instandsetzungen von PRV, welche in einer Werkstatt erfolgen, nicht jedoch für die Einstellung eingebauter PRV am Anwendungsort.
Anhang A ist ein informativer Anhang, der ein Stichprobenverfahren zur erneuten Qualifizierung von PRV enthält, das ausschließlich für die erneute Qualifizierung von seriengefertigten Druckbehältern mit serien¬gefertigten PRV am Anwendungsort angewendet werden sollte.

Équipements pour GPL et leurs accessoires - Soupapes de sécurité pour réservoirs de GPL sous pression - Exigences de reconditionnement

La présente Norme européenne spécifie les exigences liées au reconditionnement, au renouvellement des essais et à la certification des soupapes de sécurité destinées aux réservoirs de GPL sous pression couverts par le domaine d'application de l'EN 14129.
La présente Norme européenne s'applique au renouvellement des essais et au reconditionnement des soupapes de sécurité réalisés en atelier et ne s'applique pas au réglage sur site des soupapes de sécurité installées.
L'Annexe A est une annexe informative détaillant une méthode d'échantillonnage pour la requalification de soupapes de sécurité. Il ne convient d'utiliser cette annexe qu'en cas de requalification sur site de réservoirs sous pression produits en série et équipés de soupapes de sécurité produites en série.
