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 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 Electrotechnical 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 the 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 part of ISO 11119 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 11119-2 was prepared by Technical Committee ISO/TC 58, Gas cylinders, Subcommittee SC 3, Cylinder design. ISO 11119 consists of the following parts, under the general title Gas cylinders of composite construction Specification and test methods: Part 1: Hoop wrapped composite gas cylinders Part 2: Fully wrapped fibre reinforced composite gas cylinders with load-sharing metal liners Part 3: Fully wrapped fibre reinforced composite gas cylinders with non-metallic and non-load-sharing metal liners Annexes A and B of this part of ISO 11119 are for information only.

The objective is to balance design and economic efficiency against international acceptance and universal utility. ISO 11119 aims to eliminate the concern about climate, duplicate inspection and restrictions currently existing because of lack of definitive International Standards and should not be construed as reflecting on the suitability of the practice of any nation or region.

The cylinders are constructed in the form of a seamless metallic liner over-wrapped with carbon fibre or aramid fibre or glass fibre (or a mixture thereof) in a resin matrix, to provide circumferential reinforcement. This part of ISO 11119 addresses fully wrapped composite cylinders with a load-sharing liner (i.e. a liner that shares the load of the overall cylinder design) and a design life from 10 a to non-limited life. For cylinders with design life in excess of 15 a, and in order for these cylinders to remain in service beyond 15 a, requalification of these cylinders is recommended. This part of ISO 11119 does not address the design, fitting and performance of removable protective sleeves. Where these are fitted they should be considered separately. NOTE 1 ISO 11439 applies to cylinders intended for use as fuel containers on natural gas vehicles. NOTE 2 ISO 11623 covers periodic inspection and retesting of composite cylinders. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of ISO 11119.
