Foreword
This document (EN 14025:2003) has been prepared by Technical Committee CEN/TC 296 “Tanks for the transport
of dangerous goods”, the secretariat of which is held 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by endorsement, at the latest by April 2004, and conflicting national standards shall be withdrawn at the latest by
April 2004.
This European Standard 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.
The standard is submitted 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/or in the technical annexes of the ADR.
Annexes A and B are informative.
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, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal,
Slovakia, Spain, Sweden, Switzerland and the United Kingdom.
1 Scope
This European Standard specifies the minimum requirements for the design and construction of metallic pressure
tanks having a maximum working pressure exceeding 50 kPa (0,5 bar) for the transport of dangerous goods by road
and rail. This standard includes requirements for openings, closures and structural equipment; it does not cover
requirements of service equipment. For road tankers for the transport of LPG see EN 12493. For tanks for the
transport of cryogenic liquids see EN 13530-1 and -2.
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 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. For undated references the latest edition of the
publication referred to applies (including amendments).
