Foreword
This document (EN 14025:2008) has been prepared by Technical Committee CEN/TC 296 “Tanks for 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by endorsement, at the latest by November 2008, and conflicting national standards shall be withdrawn at the latest
by November 2008.
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 supersedes EN 14025:2003.
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.
This standard is submitted for reference into the RID and/or in the technical 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, Bulgaria, Cyprus, Czech Republic,
Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,
Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, 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 EN 13530-2.
NOTE Design and construction of pressure tanks according to the scope of this standard are primarily subject to the
requirements of RID/ADR, 6.8.2.1, 6.8.3.1 and 6.8.5, as relevant. In addition, the relevant requirements of RID/ADR, columns 12
and 13 of Table A to chapter 3.2, 4.3 and 6.8.2.4 shall be met. For the structural equipment subsections 6.8.2.2 and 6.8.3.2
apply, as relevant. The definitions of RID/ADR 1.2.1 are referred to.
