ISO (the International Organization for Standardization) 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 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 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. 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 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 14313 was prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore structures for petroleum, petrochemical and natural gas industries, Subcommittee SC 2, Pipeline transportation systems. This second edition cancels and replaces the first edition (ISO 14313:1999), which has been technically revised, principally by the following. Clause 2, on the requirements for conformity to this International Standard, has been added for clarification. Clause 7, on the requirements for allowable stresses and allowable deflection on design, has been revised and clarified. Clause 8, on material, has been revised to align the requirements with global industry practice for carbon content and carbon equivalent for pressure-containing, pressure-controlling, welding ends and parts requiring welding. New requirements on repairs and NDE of welding repairs have been added to Clause 9 on Welding. A new table (Table D.2) has been added to Annex D (informative) to provide more guidance for those requirements listed in the text as requiring agreement between the manufacturer/purchaser. v API Specification 60 / ISO 14313 Introduction This International Standard is the result of harmonizing the requirements of ISO 14313:1999 and API Spec 60-2002[5]. The revision of ISO 14313 is developed based on input from both ISO/TC67/SC2 WG2 and API 60 TG technical experts. The technical revisions have been made In order to accommodate the needs of industry and to move this I nternational Standard to a higher level of service to the petroleum and natural gas industry. Users of this International Standard should be aware that further or differing requirements can be needed for individual applications. This International Standard is not intended to inhibit a manufacturer from offering, or the purchaser from accepting, alternative equipment or engineering solutions for the individual application. This may be particularly applicable where there is innovative or developing technology. Where an alternative is offered, the manufacturer should identify any variations from this International Standard and provide details. vi
