16、ll rights reserved vForeword 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 s
17、ubject 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
18、(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 comm
19、ittees 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
20、be held responsible for identifying any or all such patent rights. ISO 12490 was prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore structures for petroleum, petrochemical and natural gas industries, Subcommittee SC 2, Pipeline transporation systems.

21、490:2011(E) vi ISO 2011 All rights reservedIntroduction It is necessary that users of this International Standard be aware 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
22、 from 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 the responsibility of the vendor to identify any variations from this Interna
23、tional Standard and provide details. BS ISO 12490:2011INTERNATIONAL STANDARD ISO 12490:2011(E) ISO 2011 All rights reserved 1Petroleum and natural gas industries Mechanical integrity and sizing of actuators and mounting kits for pipeline valves 1 Scope This International Standard defines the require
24、ments for mechanical integrity and sizing of actuators used on valves manufactured under ISO 14313 and API Specification 6D. This International Standard is applicable to all types of electric, pneumatic and hydraulic actuators, inclusive of mounting kit, installed on pipeline valves. This Internatio
25、nal Standard is not applicable to actuators installed on control valves, valves being used for regulation, valves in sub-sea service, handheld powered devices, stand-alone manually operated gearboxes, instrument tubing and associated fittings and actuator control equipment. 2 Conformance 2.1 Units o
26、f measurement In this International Standard, data are expressed in both SI units and USC units. For a specific order item, unless otherwise stated, only one system of units shall be used, without combining data expressed in the other system. For data expressed in SI units, a comma is used as the de
27、cimal separator and a space is used as the thousands separator. For data expressed in USC units, a dot (on the line) is used as the decimal separator and a comma is used as the thousands separator. 2.2 Rounding Unless otherwise stated in this International Standard, to determine conformance with the
28、 specified requirements, observed or calculated values shall be rounded to the nearest unit in the last right-hand place of figures used in expressing the limiting value, in accordance with ISO 80000-1:2009. 2.3 Compliance with this International Standard A quality system should be applied to assist
29、 compliance with the requirements of this International Standard. NOTE ISO/TS 29001 gives sector-specific 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 th
30、e purchaser to make any investigation necessary in order to be assured of compliance by the manufacturer and to reject any material that does not comply.
