The work of preparing International Standards is normally carried out through ISO
41、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 clo
42、sely 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. Dra
43、ft 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 docu
44、ment may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 10407-2 was prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore structures for petroleum, petrochemical and natural gas industries, Subcommittee SC
45、4, Drilling and production equipment. This first edition of ISO 10407-2, together with ISO 10407-1, replaces ISO 10407:1993, which will be cancelled when both ISO 10407-1 and ISO 10407-2 have been published and which has been technically revised. ISO 10407 consists of the following parts, under the
46、general title Petroleum and natural gas industries Rotary drilling equipment: Part 2: Inspection and classification of used drill stem elements A Part 1, dealing with drill stem design and operating limits, is under development. vii Introduction Users of this International Standard should be aware t
47、hat further or differing requirements can 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 can be particularly app
48、licable 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 shall become effective on the date printed on the cover but may be used voluntarily
49、 from the date of distribution. This International Standard includes provisions of various natures. These are identified by the use of certain verbal forms: SHALL is used to indicate that a provision is MANDATORY; SHOULD is used to indicate that a provision is not mandatory, but RECOMMENDED as good practice; MAY is used to indicate that a provision is OPTIONAL; CAN is used to indicate a POSSIBILITY.
