The work of preparing International Standards is normally carried out through ISO technical committees.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. D

4、raft 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 10431 was prepared by the American Petro- leum

5、Institute (API) (as Spec 11 E, 16th edition) and was adopted, under a special “fast-track procedure”, by Technical Committee ISO/TC 67, Ma- terials, equipment and offshore structures for Petroleum and natura1 gas industries, in parallel with its approval by the ISO member bodies. 0 ISO 1993 All righ

ISO, in endorsing this API document, recognizes that in certain

8、respects the latter does not comply with all current ISO rules on the presentation and content of an International Standard. Therefore, the relevant technical body, within lSO/TC 67, will review ISO 10431:1993 and reissue it, when practicable, in a form complying with these rules. This Standard is n

9、ot intended to obviate the need for Sound engineering judgement as to when and where this Standard should be utilized and users of this Standard should be aware that additional or differing require- ments may be needed to meet the needs for the particular Service in- tended. Standards referenced her

10、ein may be replaced by other international or national Standards that tan be shown to meet or exceed the requirements of the referenced Standards.
