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 October 2014, and conflicti

15、ng national standards shall be withdrawn at the latest by October 2014. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document

16、has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. This European Standard has been submitted for reference into the RID and/or the technical annexes of the ADR. Therefore, in this context, the standards listed in the normative reference

17、s 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 technical annexes of the ADR. According to the CEN-CENELEC Internal Regulations, the national standards organizations of t

BS EN 15888:2014EN 15888:2014 (E) 4 Introduction The principal aim of a periodic inspection and testing procedure is that at the completion of the test the cylinder bundles may be

20、 reintroduced into service for a further period of time. Experience of the inspection and testing of cylinder bundles which is specified in this European Standard is an important factor when determining whether a cylinder bundle should be returned into service. Periodic inspection and testing of the

21、 bundle are carried out in line with the retest period of the cylinders within the bundle and are a legal requirement in order to comply with Directive 89/655/EEC as amended by Directive 95/63/EC as implemented into National Legislation within the European Union. NOTE In this standard retest is used

22、 as a synonym for periodic inspection and test. BS EN 15888:2014EN 15888:2014 (E) 5 1 Scope This European Standard specifies the requirements for the periodic inspection and testing of cylinder bundles containing compressed, liquefied and dissolved gas. It is also applicable to cylinder bundles cont

23、aining acetylene. This European Standard includes information regarding the maintenance of cylinder bundles. This European Standard does not cover the requirements for cylinder bundles when they are a part of a battery vehicle. For some specific application, e.g. offshore, additional requirements ma

24、y apply. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

29、is entirely gaseous at 50 C (including all gases with a critical temperature 50 C) 3.2 main valve valve which is fitted to the manifold and which is used for the isolation of the bundle BS EN 15888:2014EN 15888:2014 (E) 6 3.3 cylinder bundles transportable assembly which consists of a frame and two

30、or more cylinders each of capacity up to 150 l and with a combined capacity of not more than 3 000 l, or 1 000 l in the case of toxic gases, connected to a manifold by cylinder valves or fittings such that the cylinders are filled, transported and emptied without disassembling 3.4 frame structural a

31、nd non-structural members of a bundle which combine all other components together, whilst providing protection for the bundles cylinders, valves and manifold and which enable the bundle to be transported 3.5 cylinder valve valve which is fitted into a cylinder and to which a manifold is connected in

32、 a bundle 3.6 cylinder fitting component with no gas shut-off capability which serves as a method for connecting a bundles manifold to its individual cylinders when cylinder valves are not fitted to the cylinders 3.7 manifold piping system for connecting a bundles cylinder valves or cylinder fitting

34、 tare weight of the bundle and the maximum permissible filling weight Note 1 to entry: In International Standards, weight is equivalent to a force, expressed in Newtons. However, in common parlance (as used in terms defined in this European Standard), the word “weight” continues to be used to mean m

35、ass, although this practice is deprecated (see ISO 80000-4). Note 2 to entry: To be understood as “maximum gross mass” as per RID/ADR. 3.11 liquefied gas gas which when packaged under pressure for transport is partially liquid at temperatures above 50 C Note 1 to entry: A distinction is made between

36、: a) high pressure liquefied gas; a gas with a critical temperature between 50 C and +65 C; and b) low pressure liquefied gas; a gas with a critical temperature above +65 C.

39、ll be submitted to periodic inspections and tests. The procedures shown in a) to f), where applicable, form the requirements for such inspections and tests and are explained more fully in later clauses: a) identification of cylinders/bundles and preparation for inspection and tests; b) depressurizat

40、ion of manifold and individual cylinders; c) disassembly of the bundle including safe de-valving and removal of cylinder fittings; d) cylinder periodic inspection and test (see EN 1802, EN 1968, EN ISO 11623 or EN ISO 10462); e) assessment of the cylinder bundle frame, manifold and valve condition (

41、including cylinder and main valves); f) bundle assembly and testing. 5 Inspection and tests 5.1 General Depending upon the nature of the operation, an existing cylinder bundle may, upon dismantling, be reassembled using the same frame, cylinders and components. Alternatively, frames, cylinders and c

42、omponents may be interchanged for ease of operation during the periodic inspection and testing. If at any stage, replacement of any part of the bundle (frame, cylinders or components) takes place, the new parts shall be compatible with the original design type specification. 5.2 Identification of cy

43、linders/bundles and preparation for inspection and tests On receipt for inspection, the gas content within the bundle shall be identified. Before any work is carried out, the relevant cylinder data and ownership shall be identified. BS EN 15888:2014EN 15888:2014 (E) 8 5.3 Depressurization of manifol

44、d and individual cylinders Cylinders, and any pressure retaining accessories, shall be depressurized and emptied in a safe, controlled manner before carrying out any inspection or test work. Particular attention shall be given to cylinders containing flammable, oxidizing, corrosive or toxic gases to

45、 eliminate risks at the internal inspection stage (e.g. by purging the cylinders and associated fittings prior to de-valving). Before removing any pressure retaining accessory (e.g. a valve or flange) a positive check shall be performed to ensure that the cylinder and associated fittings do not cont

46、ain gas under pressure. This may be performed as described in Annex A. Main or cylinders valves which are found to be inoperative or blocked shall be treated as described in Annex A. In the case of cylinders disassembled from bundles and not equipped with cylinder valves, the connecting T-junctions

47、shall be checked to determine whether the gas is able to pass freely from the cylinders (e.g. using the device shown in Figure A.1). NOTE Provided the requirements described in this clause have been met, the manifold and cylinders can be depressurized safely and the corresponding valve can be remove

48、d. 5.4 Disassembly of the bundle including safe de-valving/removal of cylinder fittings The main valve and manifold shall be safely removed from the cylinders/frame (see 5.3). The cylinders, manifold and frame shall be segregated (see 5.1). 5.5 Cylinder periodic inspection and test Cylinders shall b

49、e subjected to a periodic inspection and test as specified for the particular cylinder type (as described in EN 1968, EN 1802, EN ISO 11623 and EN ISO 10462. New cylinders provided they are within the test period need not be retested. 5.6 Assessment of the cylinder bundle frame, manifold and valve condition (including cylinder and main valves) If any of the existing frame, manifold and valves are intended to be reused, the relevant equipment shall be inspected in accordance with the following requirements. Whenever valves are reused, they shall be inspec
