The work of preparing International Standards is normally carried out through I
35、SO 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 ISO, also take part in the work. ISO collaborates
36、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 committees is to prepare International Standards.
37、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 possibility that some of the elements of this d
38、ocument may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 10437 was prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore structures for petroleum, petrochemical and natural gas industries, Subcommittee SC

ENISO10437:2003IS:73401 O3002(E) I SO 3002 All irhgts seredevr viiIntroduction This International Standard is based on API Std 612, fourth edition, J
40、une 1995. Users of this International 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 soluti
41、ons 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. This International Standard requires the purch
42、aser to specify certain details and features. A bullet ( ) at the beginning of a clause or subclause indicates that either a decision is required or further information is to be provided by the purchaser. This information or decision should be indicated on the data sheets; otherwise it should be sta
43、ted in the quotation request (inquiry) or in the order. In this International Standard, where practical, US Customary units have been included in brackets for information.
