LPG equipment and accessories - Sealing caps and plugs for LPG cylinder and pressure vessel valves - Specification and testing

This European Standard specifies the design, testing and marking requirements for caps and plugs used to form a pressure tight seal with liquefied petroleum gas (LPG) cylinder valves and pressure vessel valves. Sealing caps and plugs provide an additional seal for self-closing and manually operated valves.  
Dust caps and tamper evident seals that do not form an additional seal as part of their design are excluded from the scope of this European Standard.
Cylinder valve caps and plugs may be used with valves for liquid and vapour manufactured in accordance with EN ISO 14245 and EN ISO 15995.
Pressure vessel valve caps and plugs may be used with valves for liquid and vapour manufactured in accordance with EN 13175. Occasional liquid withdrawal valve caps and plugs are excluded from the scope of this European Standard.
Reusable and single use sealing caps and plugs are included in this European Standard.
This European Standard does not exclude the use of other designs that provide an equivalent level of safety.
NOTE   The term "pressure vessel" does not include LPG tank vehicles, also called "road tankers", in CEN/TC 286 standards.

Flüssiggas-Geräte und Ausrüstungsteile - Dichtkappen und Dichtstopfen für Flaschen und Behälter für Flüssiggas (LPG) - Spezifikation und Prüfungen

Dieses Dokument legt die Anforderungen an die Auslegung, Prüfung und Kennzeichnung von Kappen und Stopfen fest, die zur Herstellung einer druckdichten Abdichtung für Ventile für Flaschen und Druckbehälter für Flüssiggas (LPG, en: liquefied petroleum gas) verwendet werden. Dichtkappen und Dichtstopfen stellen eine zusätzliche Abdichtung für selbstschließende und handbetätigte Ventile sicher.
Schutzkappen oder Schmutzkappen und Originalverschlüsse, bei denen die Herstellung einer zusätzlichen Abdichtung nicht Bestandteil ihrer Auslegung ist, fallen nicht in den Anwendungsbereich dieses Dokuments.
Flaschenventilkappen und  stopfen können für nach EN ISO 14245 und EN ISO 15995 hergestellte Ventile für die Flüssigphase und Gasphase verwendet werden.
Druckbehälterventilkappen und  stopfen können für nach EN 13175 hergestellte Ventile für die Flüssigphase und Gasphase verwendet werden. Kappen und Stopfen für Ventile für die gelegentliche Entnahme aus der Flüssigphase. sind vom Anwendungsbereich des Dokuments ausgeschlossen.
Wiederverwendbare Dichtkappen und Einwegdichtkappen und -stopfen sind im Anwendungsbereich des Dokuments enthalten.
Dieses Dokument schließt die Verwendung anderer Auslegungen, die ein gleichwertiges Sicherheitsniveau sicherstellen, nicht aus.
ANMERKUNG   Der Begriff „Druckbehälter“ umfasst keine LPG-Tankfahrzeuge, auch in Normen des CEN/TC 286 „Straßentankwagen“ genannt.

Les bouchons et obturateurs des vannes de réservoirs sous pression peuvent être utilisés avec des vannes pour liquides et gaz fabriquées conformément à l'EN 13175. Le présent document ne traite pas des bouchons et obturateurs des clapets de reprise liquide.
Le présent document couvre à la fois les bouchons et obturateurs d'étanchéité réutilisables et à usage unique.
Le présent document n'exclut pas l'utilisation d'autres conceptions assurant un niveau de sécurité équivalent.
NOTE Le terme « réservoir sous pression » n'inclut pas les véhicules-citernes pour GPL, également appelés « camions-citernes » dans les normes du CEN/TC 286.

Oprema in pribor za utekočinjeni naftni plin (UNP) - Tesnilne kape in čepi za ventile jeklenk in tlačnih posod za UNP - Specifikacija in preskušanje

Ta evropski standard določa zahteve za zasnovo, preskušanje in označevanje za kape in pokrove, ki se uporabljajo za tesnjenje pri ventilih jeklenk in tlačnih posod za utekočinjeni naftni plin (UNP). Tesnilne kape in pokrovi zagotavljajo dodatno tesnilo za samozaporne in ročno upravljane ventile.

Introduction
This document calls for the use of substances and procedures that may be injurious to health and/or the
environment if adequate precautions are not taken. It refers only to technical suitability and does not
absolve the user from legal obligations at any stage.
It is recommended that companies using this document develop an environmental management policy.
For guidance see ISO 14000 series.
Protection of the environment is a key political issue in Europe and elsewhere. For TC 286 this is covered
in CEN/TS 16765 [4] LPG equipment and accessories - Environmental considerations for CEN/TC 286
standards, and this Technical Specification should be read in conjunction with this document. The
Technical Specification provides guidance on the environmental aspects to be considered regarding
equipment and accessories produced for the LPG industry and the following is addressed:
a) design;
b) manufacture;
c) packaging;
d) use and operation; and
e) disposal.
It has been assumed in the drafting of this document that the execution of its provisions is entrusted to
appropriately qualified and experienced people.
All pressures are gauge pressures unless otherwise stated.
This document requires measurement of material properties, dimensions and pressures. All such
measurements are subject to a degree of uncertainty due to tolerances in measuring equipment etc. It
may be beneficial to refer to the leaflet, Measurement uncertainty leaflet SP INFO 2000:27 [3].

Introduction
This document calls for the use of substances and procedures that may be injurious to health and/or the
environment if adequate precautions are not taken. It refers only to technical suitability and does not
absolve the user from legal obligations at any stage.
Protection of the environment is a key political issue in Europe and elsewhere. Protection of the
environment is taken in a very broad sense. What is meant is the total life cycle aspects of, e.g. a product
on the environment, including expenditure of energy and during all phases from mining of raw materials,
fabrication, packaging, distribution, use, scrapping, recycling of materials, etc.
NOTE Annex C indicates the clauses in this document that address environmental issues.
Provisions need to be restricted to a general guidance. Limit values are specified in national laws.
It is recommended that manufacturers develop an environmental management policy. For guidance, see
the EN ISO 14000 series.
It has been assumed in the drafting of this document that the execution of its provisions is entrusted to
appropriately qualified and experienced people.
All pressures are gauge pressures unless otherwise stated.
This document requires measurement of material properties, dimensions and pressures. All such
measurements are subject to a degree of uncertainty due to tolerances in measuring equipment etc. It
