29、. 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
30、-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
31、 3. 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. International Standard ISO 11120 was prepared by Technical Committee

34、dwide usage. The objective is to balance design and economic efficiency against international acceptance and universal utility. This International Standard aims to eliminate concern about climate, duplicate inspections and restrictions currently existing because of lack of definitive International S

This International Standard should not be construed as reflecting on the suitability of the practice of any nation or region. 1 Scope This International Standard specifies minimum requirements for the material, design, construction and workmanship, manufacturing processes and tests at manu
36、facture of refillable quenched and tempered seamless steel tubes of water capacities from 150 l up to and including 3 000 l for compressed and liquefied gases exposed to extreme world-wide ambient temperatures (normally between 50 C and + 65 C). This International Standard is applicable to tubes wit
37、h a maximum tensile strength Rm of less than 1 100 MPa. These tubes can be used alone or in batteries to equip trailers or skids (ISO modules) for the transportation and distribution of compressed gases. This International Standard does not include consideration of any additional stresses that may o

In order to ensure that tubes are in compliance with this International Standard they shall be subject to inspection in accordance wi
47、th clauses 9 and 10 by an authorized inspection body (hereafter referred to as “the inspector”) recognized in the countries of use. The inspector shall be competent for inspection of tubes. 6 Materials 6.1 General requirements 6.1.1 Materials for the manufacture of tubes shall meet the requirements
48、of 6.2, 6.3 and 6.4. Steels for the fabrication of tubes shall be of nationally or internationally recognized compositions having proven reliability. These steels shall fall within one of the chemical groups as shown in Annex A. New steel compositions, and steels for which limited experience exists
49、in tube/cylinder service, shall be fully tested and approved by a national authority and have been manufactured from not less than five casts of steel. The manufacturer of the finished tube shall provide a detailed specification with tolerances for the supplied tubing including: chemical composition; dimensions; surface quality. 6.1.2 The steel used for the fabrication of tubes shall be fully killed. 6.1.3 The manufacturer of the tubing shall supply certificates of a reference heat treatment r
