This European Standard shall be give
20、n the status of a national standard, either by publication of an identical text or by endorsement, at the latest by August 2002, and conflicting national standards shall be withdrawn at the latest by August 2002. In this standard the annexes B, C, D, E, F, G and H are normative and the annexes A and
21、 I are informative. 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 t
22、he RID and/or 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 the t
23、echnical annexes of the ADR. 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, France, Germany, Greece, Iceland, Ireland, Italy, Luxembo

25、 that at the completion of the test the cylinders may be reintroduced into service for a further period of time. Experience of the inspection and testing of cylinders which is specified in this European Standard is an important factor when determining whether a cylinder should be returned into servi
26、ce.

27、m bundles) intended for compressed and liquefied gases under pressure, of water capacity from 0,5 l up to 150 l. NOTE As 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
28、to verify the integrity of such gas cylinders to be reintroduced into service for a further period of time. It also defines a procedure to qualify existing gas cylinders for free movement between member states of the European Union (see annex A). This standard does not apply to periodic inspection a
29、nd testing of acetylene cylinders or composite (fully wrapped or hoop-wrapped) aluminium alloy cylinders. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate place in the
30、 text, and the publications are listed hereafter. 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.

37、operation, cylinders shall be periodically submitted to inspection and test in accordance with annex B. A cylinder shall fall due for a periodic inspection and test on its first receipt by a filler after the expiry of the interval in annex B. NOTETable B.1 gives a list of the intervals between perio
38、dic inspections for some gases which complies with the current RID/ADR regulations and also gives recommendations which could be subsequently adopted by the RID/ADR regulations. Provided the cylinder has been subjected to normal conditions of use and has not been subjected to abusive and abnormal co
39、nditions rendering the cylinder unsafe, there is no general requirement for the user to return a gas cylinder before the contents have been used even though the test interval may have lapsed. However it is suggested that cylinders are retested within a period not exceeding twice the time interval. I
40、n the case of cylinders used for emergency purposes (e.g. fire extinguishers, breathing apparatus), it is the responsibility of the person in possession (owner or user) to submit it for a periodic inspection within the interval specified in annex B or as specified in the relevant cylinder design sta
41、ndard/regulation, if this is shorter. 4 List of procedures for periodic inspection and test The inspection and test shall be carried out only by competent persons who shall ensure that the cylinders are fit for continued safe use. NOTEA competent person is a person who has the necessary technical kn
42、owledge, experience and authority to assess and approve materials for use with gases and to define any special conditions of use that are necessary. Such a person will also normally be formally qualified in an appropriate technical discipline. Each cylinder shall be submitted to periodic inspection
43、and test. The following procedures form the requirements for such inspection and test, and are explained more fully in later clauses: - identification of cylinder and preparation for inspection and test (clause 5); - external visual inspection (clause 6); - internal visual inspection (clause 7); - s
44、upplementary tests (clause 8); - inspection of cylinder neck/shoulder (clause 9); - pressure test or ultrasonic test (clause 10); - inspection of valve (clause 11); - final operations (clause 12); - rejection and rendering cylinders unserviceable (clause 13). Where cylinders are manufactured accordi
45、ng to National Regulations and are intended to be qualified under the Transportable Pressure Equipment Directive (TPED) for free movement and use between member states of the European Union, additional requirements are specified in annex A. It is recommended that the above listed tests are performed
46、 in the suggested sequence. In particular the internal visual examination (clause 7) should be carried out before the pressure test or ultrasonic test (clause 10). Cylinders which fail the inspection or tests shall be rejected (see clause 13). When, after the above tests, doubts still exist as to th
47、e extent of a defect or the condition of a cylinder, then additional tests may be performed in accordance with clause 8, until such doubts are positively resolved or the cylinder shall be rendered unserviceable. Some cylinders rejected during periodic inspection and test may be recovered in accordan
48、ce with annex C.

Therefore, the maximum temperature for any operation shall be limited. (See 12.1.
49、2.) 5 Identification of cylinder and preparation for inspection and test Before any work is carried out, the relevant cylinder data (e.g. see EN 1089-1) and its contents and ownership shall be identified. The cylinders shall be depressurised and emptied in a safe, controlled manner before proceeding. Particular attention shall be given to cylinders containing flammable, oxidising and toxic gases to eliminate risks at the internal inspection stage. Cylinders with incorrect markings, unknown gas contents, or those which canno
