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, government
34、al 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. The procedures used to develop this document and those intended for its further maintenance
35、are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). Attention i

41、d viiIntroduction This International Standard is based on API Spec 5CT. Users of this International Standard are advised that 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 f
42、rom accepting, alternative equipment or engineering solutions for the individual application. This can be particularly applicable where there is innovative or developing technology. Where an alternative is offered, it is advisable that the vendor identify any variations from this International Stand
43、ard and provide details. This International Standard includes requirements of various nature. 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 practi
44、ce; MAY is used to indicate that a provision is OPTIONAL. Details of the major changes (additions, modifications and deletions) agreed by the committee, and which affect the performance of the products or the technical requirements applicable to the products, are provided for information in Annex L
45、and are indicated in this International Standard by the use of grey shading for changes in the fourth edition and yellow shading for changes in this edition. Shading is also used to indicate editorial changes. Where deletions, but no other changes, have been made, vertical bars are used in the margi
46、n adjacent to the applicable line or at each side of a cell in a table. Where a complete line or paragraph has been deleted, margin bars next to a blank line are used. While efforts have been made to ensure the accuracy of the changes indicated, the user of this International Standard is advised to
47、consider the total technical content and not only the changes identified. The user is ultimately responsible for recognising any differences between this edition and the previous edition of this International Standard. ISO expressly disclaims any liability or responsibility for loss or damage result
48、ing from inappropriate use of this International Standard on the basis of any inaccuracy in the changes identified.
