The work of preparing International Standards is normally carried out throu

25、gh 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 collabora

26、tes 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 Standar

27、ds. 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 th

28、is document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

BS EN ISO 14723:2009ISO 14723:2009(E) vi ISO 2009 All rights reservedIntroduction This International Standard is based on ISO 14313. It has been d

30、eveloped to address special requirements specific to subsea pipeline valves. It is necessary that users of this International Standard be aware that further or differing requirements can be required for individual applications. This International Standard is not intended to inhibit a contractor from

31、 offering, or the company from accepting, alternative 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 the responsibility of the manufacturer to identify any variations

32、 from this International Standard and provide details. BS EN ISO 14723:2009INTERNATIONAL STANDARD ISO 14723:2009(E) ISO 2009 All rights reserved 1Petroleum and natural gas industries Pipeline transportation systems Subsea pipeline valves 1 Scope This International Standard specifies requirements and

33、 gives recommendations for the design, manufacturing, testing and documentation of ball, check, gate and plug valves for subsea application in offshore pipeline systems meeting the requirements of ISO 13623 for the petroleum and natural gas industries. This International Standard is not applicable t

34、o valves for pressure ratings exceeding PN 420 (Class 2500). 2 Conformance 2.1 Rounding Except as otherwise required by this International Standard, to determine conformance with the specified requirements, observed or calculated values shall be rounded to the nearest unit in the last right-hand pla

35、ce of figures used in expressing the limiting value, in accordance with the rounding method of ISO 31-0:1992, Annex B, Rule A. 2.2 Compliance to standard A quality system should be applied to assist compliance with the requirements of this International Standard. NOTE ISO/TS 29001 gives sector-speci

36、fic guidance on quality management systems. The manufacturer shall be responsible for complying with all of the applicable requirements of this International Standard. It shall be permissible for the purchaser to make any investigation necessary in order to be assured of compliance by the manufactur

37、er and to reject any material that does not comply. 3 Normative references The following referenced documents are indispensable for the application of this document.
