8、 (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 interested in a subject for which a technical com
9、mittee 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 electrot
10、echnical standardization. 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 mem
11、ber 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 document may be the subject of patent rights. ISO shall not be held responsible for identify
12、ing any or all such patent rights. ISO 11119-1 was prepared by Technical Committee ISO/TC 58, Gas cylinders, Subcommittee SC 3, Cylinder design. This edition cancels and replaces ISO 11119-1:2002.

15、on The purpose of this International Standard is to provide a specification for the design, manufacture, inspection and testing of cylinders for worldwide usage. The objective is to balance design and economic efficiency against international acceptance and universal utility. This International Stan
16、dard aims to eliminate the concern about climate, duplicate inspection and restrictions currently existing because of lack of definitive International Standards and is not to be construed as reflecting on the suitability of the practice of any nation or region. This part of ISO 11119 addresses the g

18、ylinders and tubes Design, construction and testing Part 1: Hoop wrapped fibre reinforced composite gas cylinders and tubes up to 450 l 1 Scope This part of ISO 11119 specifies requirements for composite gas cylinders and tubes between 0,5 l and 450 l water capacity, for the storage and conveyance o
19、f compressed or liquefied gases. This part of ISO 11119 applies to type 2 hoop wrapped cylinder or tube with a load-sharing metal liner and composite reinforcement on the cylindrical portion only. This part of ISO 11119 is limited to cylinders and tubes with composite reinforcement of carbon fibre,
20、aramid fibre or glass fibre (or a mixture thereof) within a matrix or steel wire to provide circumferential reinforcement. Cylinders complying with this part of ISO 11119 have a minimum design life of 15 years. This part of ISO 11119 does not address the design, fitting, and performance of removable
21、 protective sleeves. NOTE ISO 11439 5applies to cylinders intended for use as fuel containers on natural gas vehicles and ISO 11623 6covers periodic inspection and re-testing of composite cylinders. 2 Normative references The following referenced documents are indispensable for the application of th

40、 has been written so that it is suitable for use with the conformity assessment system of the Recommendations on the transport of dangerous goods: Model regulations developed by the United Nations (Reference 15). Attention is drawn to requirements in specified relevant national regulations of the co
41、untry (countries) where the cylinders are intended to be used that might override the requirements given in this part of ISO 11119. To ensure that the cylinders conform to this part of ISO 11119, they shall be subject to inspection and testing in accordance with Clauses 6, 7, 8, and 9 by an inspecti
42、on body (hereafter referred to as “the inspector”) authorized to do so. Example forms of certificates that can be used are shown in Annexes A and B. Equipment used for measurement, testing, and examination during production shall be maintained and calibrated within a documented quality management sy

44、866. Relevant sections are those covering materials, thermal treatments, neck design, construction and workmanship, and mechanical tests. This excludes the design requirements, since these are specified by the manufacturer for the design of the composite cylinder (see 7.2.2). 6.1.2 The materials use
45、d shall be of uniform and consistent quality. The composite cylinder manufacturer shall verify that each new batch of materials has the correct properties and is of satisfactory quality, and shall maintain records so that the cast of material and the heat treatment batch (where applicable) used for
46、the manufacture of each cylinder can be identified. 6.1.3 The liner shall be manufactured from a metal or alloy suitable for containing the gas in accordance with ISO 11114-1. 6.1.4 When a neck ring is provided, it shall be of a material compatible with that of the cylinder, and shall be securely at
47、tached by a method appropriate to the liner material. 6.2 Composite materials 6.2.1 The overwrap filament materials shall be carbon fibre or aramid fibre or glass fibre (or any mixture thereof) or steel wire. 6.2.2 The matrix shall be a polymer suited to the application, environment, and intended li
