13、rganization 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 interested in a subject for which a technical committee has been estab
14、lished 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 Electrotechnical Commission (IEC) on all matters of electrotechnical standardizat
15、ion.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
16、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 document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such pate

18、ion and testing of a welded steel cylinder necessary to facilitate sub-atmospheric pressure gas packaging technology on a worldwide basis. The specifications given are based on knowledge of, and experience with, materials, design requirements, manufacturing processes and control at manufacture of cy
19、linders in common use in the countries of the ISO member bodies. With respect to those aspects concerning construction materials, approval of design rules and inspection during manufacture which are subject to national or international regulations, it is necessary for interested parties to ensure th
20、at, in the practical application of this International Standard, the requirements of the relevant authority are also satisfied.The pressure shell of the cylinder is fabricated by manufacturing a cylindrical shape with a base and welding a machined plug (boss) or semi-ellipsoidal or torispherical sha
21、pe onto the open end of the shell to form the cylinder. This method of fabrication allows for insertion of material prior to sealing the cylinder.A further objective of this International Standard is to balance design and economic efficiency against international acceptance and universal utility. It
22、 aims to eliminate the concerns about climate, duplicate inspections and restrictions currently existing because of lack of definitive International Standards. It should not be construed as reflecting on the suitability of the practices of any nation or region.ISO 11513:2011(E) ISO 2011 All rights r

24、d requires the use of substances and procedures that may be injurious to health if adequate precautions are not taken. It refers only to technical suitability and does not absolve the user from legal obligations relating to health and safety at any stage. It has been assumed in the drafting of this
25、International Standard that the execution of its provisions is entrusted to appropriately qualified and experienced people.1 ScopeThis International Standard specifies minimum requirements for the material, design, construction, workmanship, examination and testing at manufacture of refillable welde
26、d steel cylinders for the sub-atmospheric pressure storage of liquefied and compressed gases. It only applies to the cylinders themselves, irrespective of the materials contained therein (e.g. adsorbents, media, materials and/or gases) and other related applications. The cylinders have a test pressu
27、re not greater than 42 bar and a water capacity from 0,5 l up to and including 12 l exposed to ambient temperatures for the purpose of facilitating the sub-atmospheric pressure storage of liquefied and compressed gases. Inspection at the time of fill is specified in Annex A and periodic inspection a
28、nd testing is specified in Annex B.High-pressure and low-pressure liquefied gases as specified in Annex C can be suitably filled into these cylinders. The filling pressure will be less than one bar gauge at 21 C.2 Normative referencesThe following referenced documents are indispensable for the appli
