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of an identical text or by endorsement, at the latest by October 2009, and conflicting national standards shall be withdrawn at the lates
14、t by October 2009. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

18、ction This International Standard has been prepared on the basis of the 14th revised edition of the United Nations Recommendations on the Transport of Dangerous Goods Model Regulations. It is intended to be applied at the time of cylinder manufacture. However, it could be applied by the cylinder use
19、r during use operations, e.g. the stamping of “empty weight” (item 10 in Figures A.1, A.2 and A.3) on to cylinders not so marked at the time of manufacture. Some stamp markings include the year and date. The order of these time elements is given with the most significant figures (the year) to the le
20、ft, in accordance with the rules given in ISO 8601. EN ISO 13769:2009 (E) DIN EN ISO 13769:2009-07 41 Scope This International Standard specifies stamp marking of refillable transportable gas cylinders and tubes of volume greater than 0,5 l and less than or equal to 3 000 l, including: steel and alu
21、minium gas cylinders; composite gas cylinders; acetylene cylinders; LPG cylinders (see Annex B). These are hereafter referred to as “cylinders”. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition ci
22、ted applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 11114-1:1997, Transportable gas cylinders Compatibility of cylinder and valve materials with gas contents Part 1: Metallic materials 3 Terms and definitions For the purposes of
23、this document, the following terms and definitions apply. 3.1 permanent marking stamp marking marking applied to cylinders by hard metal stamping, engraving, casting or other similar methods NOTE 1 This marking remains legible during the entire lifespan of the cylinder. NOTE 2 For composite cylinder
24、s, permanent markings may be achieved by use of a printed label encapsulated either by placing it under the resin or by covering it with a permanent transparent coating on the shoulder or the side wall of the cylinder (see also 4.3). 3.2 durable marking marking such as stencilling (marking of the it
25、em using inks and/or paints), labelling (in accordance with e.g. ISO 7225) or other suitable methods NOTE This marking can be modified but has to remain legible for a limited period. 5EN ISO 13769:2009 (E) DIN EN ISO 13769:2009-07 4 Application of stamp markings 4.1 General Markings listed in Table
26、1 consist of manufacturing, operational and certification stamp marks. See 4.3 for the arrangement of stamp marks. Additional markings may be applied as agreed by the interested parties, provided the layout does not cause any confusion in their interpretation and the clarity of the other mandatory m
27、arkings is not affected. 4.2 Workmanship The stamp markings shown in Table 1 shall be applied permanently and legibly in such a way that the integrity of the cylinder is unaffected, e.g. on a reinforced part of the cylinder or on a permanent attachment. For welded cylinders, some stamp markings will
28、 appear on a welded identity plate or on another part permanently attached to the cylinder and not subject to gas pressure. For composite cylinders, permanent markings may be achieved by use of a printed label encapsulated either by placing it under the resin or by covering it with a permanent trans
29、parent coating on the shoulder or the side wall of the cylinder (see 4.3). Except for the “UN” mark, the characters in the stamp markings shall be at least 5 mm in height. On cylinders with an outside diameter less than 140 mm, this height may be reduced, but in no case shall the characters be less
30、than 2,5 mm in height. The minimum size of the “UN” mark shall be 10 mm for cylinders with a diameter greater than or equal to 140 mm and 5 mm for cylinders with a diameter less than 140 mm. The depth of the characters in the stamp markings made by any method shall be such that they are legible and
31、durable under all operating conditions. The stamp marking tools used shall have such radii as are necessary to prevent the formation of sharp notches. It is recommended that the radius of the stamp marking tool is not less than 0,2 mm. Different values can be used, but it shall be demonstrated by fa
32、tigue and burst tests in accordance with the design standard or equivalent that the failure does not initiate in the markings. 4.3 Arrangement and position of stamp markings All stamp markings described in Table 1 shall appear consecutively in the sequence given in the figures in Annex A, which indi
33、cates the arrangement of the stamp markings. The United Nations Model Regulations distinguish between different groups of stamp marks and give them an explicit place in the arrangement of certain markings. In Figure A.1 and Figure A.2, the top group of stamp marks includes manufacturing marks (12, 2
34、, 3, 4, 6). The group of stamp marks in the middle includes operational marks (13, 10, 11, 17, 7). The bottom group of stamp marks includes certification marks (27, 1, 28, 8, 9). In Figure A.3, the top row includes manufacturing marks. The second and third rows include operational marks and the bott
35、om row includes certification stamp marks. Annex B includes examples of positions of stamp markings for metallic LPG cylinders. When an identity plate or label (for composite cylinders) is used, all the stamp markings may be on a single plate or label, provided the layout does not cause any confusio
36、n in their interpretation and follows the requirements of Table 1. For hoop-wrapped composite cylinders, when a label under the resin is used, for traceability purposes at least the manufacturers identification and the manufacturing serial number shall be duplicated by stamping them on the shoulder
