11、onal 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 established has the right to be represented on that committee. Internat

12、ional 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. The procedures used to develop this document and those intend

13、ed for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted.

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 composite gas cylinders and tubes up to 450 l Part 2: Fully wrapped fibre reinforced

18、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 Part 4: Fully wrapped fibre reinforced composite gas cylinders up to 150 l with loa

The objective is to balance design and economic

20、 efficiency against international acceptance and universal utility. This part of ISO 11119 aims to eliminate the concern about climate, duplicate inspection, and restrictions currently existing because of a lack of definitive International Standards and is not to be construed as reflecting on the su

21、itability of the practice of any nation or region. It is possible that some procedures and tests will require precautions to be taken for the health and/or safety of the operator(s). Safety, health, and environmental concerns are not addressed and is to be addressed by those who wish to implement th

22、is International Standard. This part of ISO 11119 is intended to be used under a variety of national and international regulatory regimes. Where there is any conflict between this part of ISO 11119 and any applicable regulation, the regulation always takes precedence. This part of ISO 11119 has been

23、 written so that it is suitable to be referenced in the UN Model Regulations. 1 Annexes A and B of this part of ISO 11119 are for information only. Annex C of this part of ISO 11119 is normative.vi ISO 2016 All rights reserved Gas cylinders Refillable composite gas cylinders Design, construction and

24、 testing Part 4: Fully wrapped fibre reinforced composite gas cylinders up to 150 l with load-sharing welded metallic liners 1 Scope This part of ISO 11119 specifies requirements for composite gas cylinders with load-sharing welded liners between 0,5 l and 150 l water capacity and a maximum test pre

25、ssure of 450 bar for the storage and conveyance of compressed or liquefied gases. NOTE 1 1 bar = 10 5 Pa = 10 5 N/m 2 . The cylinders are constructed in the form of a welded stainless steel liner or welded ferritic steel liner or welded aluminium alloy liner and overwrapped with carbon fibre or aram

26、id fibre or glass fibre (or a mixture thereof) in a matrix to provide longitudinal and circumferential reinforcement. The cylinders in this part of ISO 11119 are type 3 fully wrapped cylinders with a load-sharing metal liner and composite reinforcement on both the cylindrical portion and the dome en

27、ds. Cylinders produced in accordance with this part of ISO 11119 have a minimum design life of 15 years. Cylinders with test pressure of up to 60 bar have an unlimited design life. This part of ISO 11119 does not address the design, fitting, and performance of removable protective sleeves. This part
