Transportable gas cylinders - Cylinders for dissolved acetylene - Inspection at time of filling
This European Standard specifies minimum requirements which reflect current practice and experience for inspection at time of filling of cylinders of water capacity up to 150 litres for the storage and transport of dissolved acetylene gas under pressure. The standard is not applicable to manifolded bundles or manifolded trailer cylinders. Aspects related to the inspection or testing of the porous mass, are not covered in this standard.
Ortsbewegliche Gasflaschen - Gasflaschen für gelöstes Acetylen - Prüfung zum Zeitpunkt des Füllens
Diese Norm enthält Mindestanforderungen für die Prüfung zum Zeitpunkt des Füllens, die den gegenwärtigen Stand der Technik und Erfahrung berücksichtigt und ist anwendbar auf Gasflaschen mit einem Fassungsraum bis zu 150 Litern für die Lagerung und den Transport von unter Druck gelöstem Acetylen.
Die Norm gilt nicht für Flaschen - Bündel oder auf Fahrzeugen zusammengefassten Flaschen. Die Norm enthält keine Angaben hinsichtlich der Inspektion oder Prüfung der porösen Masse.
Bouteilles a gaz transportables - Bouteilles pour acétylene dissous - Contrôle au moment du remplissage
La présente Norme européenne spécifie les exigences minimales qui refletent la pratique et l'expérience courantes en matiere de contrôle au moment du remplissage des bouteilles d'une contenance en eau maximale de 150 litres, destinées au transport et au stockage d'acétylene dissous sous pression. Cette norme n'est pas applicable aux bouteilles en cadre ou sur remorque. Les aspects relatifs aux contrôles périodiques ou a la vérification de la masse poreuse ne sont pas couverts par cette norme.

EN 12754:2001 (E)3ForewordThis European Standard has been prepared by Technical Committee CEN/TC 23 "Transportable gas cylinders",the secretariat of which is held by BSI.This European Standard shall be given the status of a national standard, either by publication of an identical text orby endorsement, at the latest by June 2002, and conflicting national standards shall be withdrawn at the latest byJune 2002.This European Standard has been submitted for reference into the RID and/or in the technical annexes of the ADR.Therefore in this context the standards listed in the normative references and covering basic requirements of theRID/ADR not addressed within the present standard are normative only when the standards themselves arereferred to in the RID and/or in the technical annexes of the ADR.Annex A is for information only and is not a mandatory part of this standard.According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden,Switzerland and the United Kingdom.SIST EN 12754:2002
EN 12754:2001 (E)4IntroductionThis Standard covers requirements which reflect current practice and experience.Each transportable gas cylinder for dissolved acetylene is inspected at time of filling in order to establish that: it has no defects such that the cylinder is unsafe for filling or continued use; it can be identified and complies with the relevant requirements with regard to marking, labelling, colour codingand completeness of its accessories; its valve functions satisfactorily; the appropriate amounts of the acetylene and solvent have been determined and charged.The cylinder filling inspection is carried out only by persons who are trained and competent in the subject, for thepurpose of ensuring that a cylinder is safe for continued use.SIST EN 12754:2002
EN 12754:2001 (E)51 ScopeThis European Standard specifies minimum requirements which reflect current practice and experience forinspection at time of filling of cylinders of water capacity up to 150 litres for the storage and transport of dissolvedacetylene gas under pressure. The standard is not applicable to manifolded bundles or manifolded trailer cylinders.Aspects related to the inspection or testing of the porous mass, are not covered in this standard.2 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text, and the publications are listed hereafter. Fordated references, subsequent amendments to or revisions of any of these publications apply to this EuropeanStandard only when incorporated in it by amendment or revision. For undated references the latest edition of thepublication referred to applies (including amendments).EN 1800:1998, Transportable gas cylinders — Acetylene cylinders — Basic requirements and definitions.3 Terms and definitionsFor the purposes of this European Standard the terms and definitions of EN 1800:1998 together with the followingapply, though there may be differences with other standards of CEN/TC 23:3.1cylinder shellpressure vessel manufactured for storage and transport, and suitable for containing a porous mass, a solvent forthe acetylene and the acetylene3.2complete cylindercylinder shell, ready to be charged with acetylene gas that is complete with porous mass, solvent, saturation gas,valve, any valve protection (permanently attached to the cylinder shell) and other permanently fixed accessories(e.g. neck ring, foot ring, fusible plugs)3.3porous masssingle or multi-component material introduced or formed in the cylinder in order to fill it and which due to its porosityallows for the absorption of the solvent/acetylene gas solutionNOTE
