19、 Technical Committee ISO/TC 58 “Gas cylinders“. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by September 2002, and conflicting national standards shall be withdrawn at the latest by September 200
20、2. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports the objectives of the framework Directives on Transport of Dangerous Goods. This European Standard has been submitted for reference into the RID and/or or
21、in the technical annexes of the ADR. Therefore in this context the standards listed in the normative references and covering basic requirements of the RID/ADR not addressed within the present standard are normative only when the standards themselves are referred to in the RID and/or in the technical
22、 annexes of the ADR. Annexes A, C and D are informative. Annex B and ZA are normative. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard : Austria, Belgium, Czech Republic, Denmark, Finland

24、 principal aim of periodic inspection and testing is that at the completion of the test the cylinders may be reintroduced into service for a further period of time. It is not possible to identify all considerations for inspecting and re-testing of composite cylinders in this publication. Questions r
25、egarding specific cylinders should be directed to the manufacturer. 1 Scope This standard specifies the requirements for periodic inspection and testing of hoop wrapped and fully wrapped composite transportable gas cylinders, with aluminium, steel or non-metallic liners or of linerless construction,
26、 intended for compressed, liquefied or dissolved gases under pressure, of water capacity from 0,5 l up to 450 l. NOTEAs far as practicable, this standard may also be applied to cylinders of less than 0,5 l water capacity. This standard specifies the requirements for periodic inspection and testing t
27、o verify the integrity of such gas cylinders for further service. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed h
28、ereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments). EN 629-2:

44、 and test on its first receipt by a filler after the expiry of the interval in Tables 1 to 4. However, a shorter period than that inTables 1 to 4 may be stipulated by the inspection body for the first re-test only. There is no general requirement for the user to return a gas cylinder before the cont
45、ents have been used even though the test interval may have lapsed. When the lifetime has expired, the cylinder shall not be refilled and shall be removed from service when presented for the next filling (see clause 13). In the case of cylinders used for emergency purposes it is the responsibility of
46、 the owner or user to submit it for a periodic inspection within the specified interval. The lists of gases in Tables 1 to 4 are intended as guides only. Reference shall be made to the manufacturer or inspection body if there is a question on the re-test period for specific gases. Licensed Copy: she
