The work of preparing Inter
21、national 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. International organizations, governmental and non-governmental, in liaison wit
22、h 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 rules given in the ISO/IEC Directives, Part 2. The main task of technica
23、l committees is to prepare International Standards. 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
24、 the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 12211 was prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore structures for petroleum, petro

26、idual 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 applicable where there is an innovative or developing technology
27、. Where an alternative is offered, it is the responsibility of the vendor to identify any variations from this International Standard and provide details. This International Standard requires the purchaser to specify certain details and features. A bullet () at the beginning of a clause or subclause
28、 indicates a requirement for the purchaser to make a decision or provide information (for information, a checklist is provided in Annex B). In this International Standard, where practical, US Customary (USC) or other units are included in parentheses for information. BS EN ISO 12211:2012BS EN ISO 12
