The work of preparing Intern
9、ational 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
10、 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 2. The main task of technical
11、 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
12、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 patent rights. ISO 11119-3 was prepared by Technical Committee ISO/TC 58, Gas cylinders, Subcommittee SC 3, Cylinder design. This second e
13、dition cancels and replaces the first edition (ISO 11119-3:2002), which has been technically revised. ISO 11119 consists of the following parts, under the general title Gas cylinders Refillable composite gas cylinders and tubes Design, construction and testing: Part 1: Hoop wrapped fibre reinforced
14、composite gas cylinders and tubes up to 450 l Part 2: Fully wrapped fibre reinforced composite gas cylinders and tubes up to 450 l with load-sharing metal liners Part 3: Fully wrapped fibre reinforced composite gas cylinders and tubes up to 450L with non-load- sharing metallic or non-metallic liners
15、 The following part is under preparation: Part 4: Fully wrapped fibre reinforced composite gas cylinders with load-sharing welded metal liners ISO 11119-3:2013(E) ISO 2013 All rights reserved vIntroduction The purpose of ISO 11119 is to provide a specification for the design, manufacture, inspection
16、 and testing of cylinders for world-wide usage. 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 defini
17、tive 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 general requirements on design, construction and initial inspection and testing of pressure receptacles of the United Nations “Recomm
18、endations on the Transport of Dangerous Goods Model Regulations.” INTERNATIONAL STANDARD ISO 11119-3:2013(E) ISO 2013 All rights reserved 1Gas cylinders Refillable composite gas cylinders and tubes Part 3: Fully wrapped fibre reinforced composite gas cylinders and tubes up to 450L with non-load-shar
19、ing metallic or non-metallic liners 1 Scope This part of ISO 11119 specifies requirements for composite gas cylinders up to 150 l water capacity and composite tubes above 150 l water capacity and up to 450 l water capacity, for the storage and conveyance of compressed or liquefied gases. The cylinde
20、rs and tubes in this part of ISO 11119 are a) Type 4 Fully Wrapped Cylinders or Tubes with a non-load sharing liner and composite reinforcement on both the cylindrical portion and the dome ends, and b) Type 5 Fully Wrapped Cylinders or Tubes without liners (including cylinders without liners manufac
21、tured from two parts joined together) and with a test pressure of less than 60 bar. The cylinders are constructed: 1) in the form of a disposable mandrel overwrapped with carbon fibre or aramid fibre or glass fibre (or a mixture thereof) in a resin matrix to provide longitudinal and circumferential
22、reinforcement; 2) in the form of two filament wound shells joined together. Cylinders and tubes manufactured and tested to this part of ISO 11119 are not intended to contain toxic, oxidizing or corrosive gases. This part of ISO 11119 is limited to cylinders and tubes with composite reinforcement of
23、carbon fibre or aramid fibre or glass fibre (or a mixture thereof) in a matrix. Cylinders and tubes manufactured and tested to 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 protective sleeves. N
