12、odies (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. International organizati
13、ons, 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 intended for its furthe
14、r 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. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2. www.iso.org/directivesAtte
15、ntion 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 patent rights.

The objective is to balance design and economic efficiency agains
18、t international acceptance and universal utility.ISO 11515 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 n
19、ation or region.ISO 11515 addresses the general requirements on design, construction and initial inspection and testing of pressure receptacles of the United Nations Recommendations on the Transport of Dangerous Goods Model Regulations.Annexes A and B of ISO 11515 are for information only.

20、All rights reserved vBS ISO 11515:2013BS ISO 11515:2013Gas cylinders Refillable composite reinforced tubes of water capacity between 450 L and 3000 L Design, construction and testing1 ScopeThis International Standard specifies minimum requirements for the design, construction and performance testing
21、 of composite reinforced tubes between 450 l and 3 000 l water capacity, for transport, storage and use of compressed or liquefied gases with test pressures up to and including 1600 bar with a design life of at least 15 years and less than or equal to 30 years. The expected service temperatures are
22、between 40 C and +65 C.The tubes defined are one of three types:Type 2: a hoop wrapped tube with a load sharing metal liner and composite reinforcement on the cylindrical portion only.Type 3: a fully wrapped tube with a load sharing metal liner and composite reinforcement on both the cylindrical por
23、tion and the dome ends.Type 4: a fully wrapped tube with a non-load sharing liner and composite reinforcement on both the cylindrical portion and the dome ends.The Type 4 tubes manufactured and tested to this International Standard are not intended to contain toxic, oxidizing or corrosive gases.This
24、 International Standard is limited to tubes with composite reinforcement of carbon fibre or aramid fibre or glass fibre (or a mixture thereof) in a matrix.Composite tubes can be used alone or in batteries to equip trailers or skids (ISO modules) or multiple element gas containers (MEGC) for the tran
25、sportation and distribution of gases. This International Standard does not include consideration of any additional stresses that can occur during service or transport, (e.g. torsional / bending stresses). However it is important that the stresses associated with mounting the tube are considered by t
26、he assembly manufacturer and the tube manufacturer.NOTE The design life of tubes according to this International Standard for transport of dangerous goods can be limited by the applicable regulations.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in th
