12、ional 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. Interna
13、tional 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. International Standards are drafted in accordance with the r
14、ules given in the ISO/IEC Directives, Part 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. Attention is drawn to the p
15、ossibility that some of the elements of this International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 15649 was prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore
16、structures for petroleum and natural gas industries, Subcommittee SC 6, Processing equipment and systems. Annexes A and B of this International Standard are for information only.ISO 15649:2001(E) v Introduction This International Standard makes normative reference to ANSI/ASME B31.3, which is presen
17、tly the worldwide basis for current standards and practices for piping systems for the petroleum and natural gas industries. It should be noted that ANSI/ASME B 31.3 itself does allow supplementary requirements if necessary for the particular application or service intended. Users of this Internatio
18、nal Standard should be aware that further or differing requirements may be needed for individual applications. This International Standard is not intended to inhibit a vendor from offering, or the purchaser from accepting alternative equipment or engineering solutions for the individual application. This may be particularly appropriate where there is innovative or developing technology. Where an alternative is offered, the vendor should identify any variations from this International Standard and provide details.
