26、s 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of an identical text or by endorsement, at the latest by January 2019, and conflicting national standards shall be withdrawn at the latest by January 2019. Attention is drawn to the possib

27、ility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 14025:2013+A1:2016. This document has been prepared under a mandate given to CEN by the European Commissi

28、on and the European Free Trade Association. Compared with EN 14025:2013+A1:2016 the following significant changes apply: a) alignment with RID/ADR as known at publication of this European Standard; b) modification of the definition “pressure tank“ (3.1.1), removing the reference to test pressure; c)

29、 deletion of requirements about the thickness of the flange of the end (6.3.3.3); d) amendment of the definition of the thickness epin Figure 8 (examples for reinforcements of shell openings) and Figure A.2 (example for a manhole opening) as well as in Formula (39); Sub-Figure 8 e) amended, new Sub-

30、Figure 8 g) added; e) external pressure resistance testing (6.4.4) replaced with a reference to EN 12972; f) requirements for the manufacturers certificate or acceptance test certificate removed and clarified that it is issued according to agreement with the buyer/customer (7.1.3); g) examination an

31、d testing of welds (7.4.3) replaced with a normative reference to EN 12972, except for requirements for the welding of the large end of a cone without a knuckle to a cylinder; h) manufacturing tolerances concerning the plate alignment (7.5.1) adjusted in accordance with EN 12972; i) explosion pressu

32、re shock resistant design of tanks (informative Annex B) amended so that dished ends are included; j) normative references updated; k) alignment of the whole document with the current principles and rules for the structure and drafting of CEN and CENELEC documents. According to the CEN-CENELEC Inter

33、nal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ir

BS EN 14025:2018EN 14025:2018 (E) 6 1 Scope This document specifies the minim

35、um 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 and sea. This document includes requirements for openings, closures and structural equipment; it does not cov

36、er requirements of service equipment. For tanks for the transport of cryogenic liquids, EN 13530-1 and EN 13530-2 apply. Design and construction of pressure tanks according to the Scope of this document are primarily subject to the requirements of RID/ADR, Subsections 6.8.2.1, 6.8.3.1 and 6.8.5, as

37、relevant. In addition, the relevant requirements of RID/ADR, Table A, columns 12 and 13, to Chapters 3.2, 4.3 and Subsection 6.8.2.4 apply. For the structural equipment RID/ADR, Subsections 6.8.2.2 and 6.8.3.2 apply, as relevant. The definitions of RID/ADR, Subsection 1.2.1, are referred to. For por

38、table tanks see also RID/ADR, Chapter 4.2 and Sections 6.7.2 and 6.7.2. In addition, the relevant requirements of RID/ADR, Table A, Columns 10 and 11 to Chapters 3.2, 4.2, and Sections 6.7.2 and 6.7.3 apply. The paragraph numbers above relate to the 2017 issue of RID/ADR which are subject to regular

39、 revisions. This can lead to temporary non-compliances with EN 14025. This document is applicable to liquefied gases including LPG; however for a dedicated LPG standard see EN 12493. If not otherwise specified, provisions which take up the whole width of the page apply to all kind of tanks. Provisio

40、ns contained in a single column apply only to: tanks according to RID/ADR Chapter 6.8 (left-hand column); portable tanks according to RID/ADR Chapter 6.7 (right-hand column). 2 Normative references The following documents are referred to in the text in such a way that some or all of their content co
