14、ld by AFNOR. 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of an identical text or by endorsement, at the latest by March 2003, and conflicting national standards shall be withdrawn at the latest by March 2003. The European Standard has been submitted
15、 for reference into the RID and/or in the technical annexes of the ADR. Therefore 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/
16、or in the technical annexes of the ADR.

Page 4 EN 13530-2 2002 1 Scope This European Standard specifies requirements for the design, fabrication, inspection and testing of large transportable vacuum ins
19、ulated cryogenic vessels of more than 1 O00 I volume, which are permanently (fixed tanks) or not permanently (demountable tanks) attached to a vehicle, for carriage by road. However, it can be used for other mode of transport providing the specific regulations/requirements are complied with. This Eu
20、ropean Standard applies to large transportable vacuum insulated cryogenic vessels for fluids specified in EN 13530-1 :2002 and does not apply to vessels designed for toxic fluids. This European Standard does not include the general vehicle requirements e.g. running gear, brakes, lighting etc. that s
21、hould be in accordance with the relevant standardclregulations. 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 he
22、reafter. 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.
