11、d Copy, (c) BSI ISO 13769:2002(E) iv Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body
12、interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotech
13、nical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by t
14、he technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this International Standard may be the subject o
15、f patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 13769 was prepared by Technical Committee ISO/TC 58, Gas cylinders, Subcommittee SC 4, Operational requirements for gas cylinders. Annex A forms a normative part of this International Standard.

It
17、is intended to be applied at the time of cylinder manufacture; however, it could be applied by the cylinder user during use operations, e.g., the stamping of “empty weight” (item 10 on Figures A.2 and A.3) on to cylinders not so marked at time of manufacture. Some stamp markings hold year and date.
18、The order of these time elements is given with the most significant digits (the year) to the left, according to the rules given in ISO 8601, Data elements and interchange formats Information exchange Representation of dates and times.

20、transportable gas cylinders and tubes of volume greater than 0,5 l and less than or equal to 3 000 l including: steel and aluminium gas cylinders; composite gas cylinders; acetylene cylinders. These are hereafter referred to as “cylinders”. Stamp marking of LPG cylinders is not covered by this Inter
21、national Standard. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However
22、, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC

25、tamping, engraving, casting or other similar methods NOTE In the case of composite cylinders some permanent markings may be achieved by use of a printed label placed under the resin. 3.2 stencilling marking of the item using inks and/or paints Licensed Copy: sheffieldun sheffieldun, na, Sun Nov 26 0

They consist of manufacturing, operational and certification stamp marks. See 4.3 for the arrangement of stamp marks. Additional mark
27、ings may be applied as requested by the cylinder owner, provided the layout does not cause any confusion in their interpretation and the clarity of the other mandatory markings is not affected. 4.2 Workmanship The stamp markings shown in Table 1 shall be stamp marked durably and legibly on a reinfor
28、ced part of the cylinder. For welded cylinders some stamp markings may appear on a welded identity plate or any other part permanently attached to the cylinder and not subject to gas pressure. For composite cylinders stamp markings may be printed on a label to be placed under the resin, on the shoul
29、der or the sidewall 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 or equal to 140 mm, this height may be reduced, but in no case shall the characters be less than 2,5 mm in h
30、eight. The “UN” mark shall be 10 mm for cylinders with a diameter greater than or equal to 140 mm, and 5 mm for cylinders less than 140 mm. The depth of the characters in the stamp markings by any method shall be such that they are legible and durable under all operating conditions. The stamps used
31、for marking shall have such radii as are necessary to prevent the formation of sharp notches (minimum acceptable radius 0,2 mm). 4.3 Arrangements of stamp marking All stamp markings described in Table 1 shall appear consecutively in the sequence given in the figures of annex A. The UN Model Regulati
32、ons distinguish between different groups of stampmarks and gives them an explicit place in the arrangement of all markings. For Figure A.1 and Figure A.2 the top grouping of stamp marks includes manufacturing marks. The second grouping of stamp marks includes operational marks. The third group of st
33、amp marks depicts certification marks. For Figure A.3, the top row includes manufacturing marks. The second and third rows include operational marks and the fourth row includes certification stamp marks. When an identity plate or label (for composite cylinders) is used, all the stamp markings may be
34、 on a single plate or label provided the layout does not cause any confusion in their interpretation and generally follows the requirements of Table 1. For hoop wrapped composite cylinders, when a label under the resin is used, the manufacturers identification and the manufacturing serial number sha
35、ll be stamped on the shoulder in conformity with annex A.

46、essed to three significant figures rounded up to the last digit. For cylinders of less than 1 kg, the empty weight shall be expressed to two significant figures rounded up to the last digit. For acetylene cylinders, it shall be expressed to at least one digit after the decimal point. EXAMPLE: Measur

In the case of liquefied gases, the water capacity in litres is expressed to three significant digits r
49、ounded down to the last digit. If the value of the minimum or nominal water capacity is an integer, the digits after the decimal point may be neglected. The actual determined volume may also be indicated on request by the customer or owner in special cases. For cylinders intended to contain acetylene the stamped water capacity shall be the actual determined volume, rounded down to three significant figures.
