24、tion) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International 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

25、represented on that committee. International organizations, governmental 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. International Standard

26、s 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. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an Interna

27、tional 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 document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 16812 was

28、 prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore structures for petroleum, petrochemical and natural gas industries, Subcommittee SC 6, Processing equipment and systems. This second edition cancels and replaces the first edition (ISO 16812:2002), which has been technical

29、ly revised.

30、ther 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 solutions for the individual application. This may be particularly applicable

31、 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. Annex A provides some optional recommended practices. A bullet (z) at the beginning of a clause or subclause indicates

32、 a requirement for the purchaser to make a decision or provide information (see checklist in Annex B). In this International Standard, where practical, US Customary (USC) units are included in parentheses for information. ANSI/API Standard 660/ISO 16812viAmerican Petroleum InstituteLicensee=China St
