33、O14661:2000ISO 16641:(0002)E ISO 0002 All irhgts serdevre v Foreword 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 commit
34、tees. 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 In
35、ternational 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 3. Draft International Standards adopted by the technical committees are circulated to the member b
36、odies 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 International Standard may be the subject of patent rights. ISO shall not be held responsible for
37、 identifying any or all such patent rights. International Standard ISO 14661 was prepared by Technical Committee ISO/TC 208, Thermal turbines for industrial application (steam turbines, gas expansion turbines).

Therefore the users of this International Standard should be aware that additional or differing requirements may be needed to meet the needs for the particular service int
39、ended. It is intended to add later, by means of an amendment, an annex containing data sheets appropriate to the text at hand.

40、neral requirements 1 Scope This International Standard specifies general requirements intended to facilitate the procurement and supply of steam turbines and gas expansion turbines primarily for industrial applications. This International Standard should serve as a basis for any application although
41、, for special applications, supplementary specifications may also be required, for example for general and special purpose industrial steam turbines used in the petroleum and natural gas industries. This International Standard is applicable to axial- and radial-flow industrial-type turbines (steam t
42、urbines and gas expansion turbines). It specifies the basic requirements for single-stage and multi-stage impulse or reaction turbines, which are not spared or are in critical service. In addition, this International Standard also specifies some requirements for driven machines, gear units, lubricat
43、ion and sealing systems, controls, instrumentation and auxiliary units for turbine plants. Exceptions to the requirements laid down in this International Standard may be agreed between the purchaser and supplier. NOTE 1 Which standard is to be applied in the individual case is the decision of the pu
44、rchaser. For instance, the purchaser of a generator-driving turbine connected to the public network will generally be responsible for complying with the technical requirements of the public network regardless which standard is specified. If the purchaser of a generator-driving turbine is also the op
45、erator of the public network or if he/she is the supplier of an independent power producer (IPP), he/she usually specifies the application of IEC 60045-1. NOTE 2 Further standards on industrial steam turbines for the Petroleum and Natural Gas Industries are ISO 10436 and ISO 10437. Information on ot
46、her relevant International Standards is given in the bibliography. NOTE 3 A bullet at the edge of the text indicates that either a decision is required or further information is to be provided by the purchaser. This information should be indicated on the data sheets (see “Introduction”) otherwise it
47、 should be stated in the quotation request or in the tender. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any o
48、f these publications do not apply. However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document r
49、eferred to applies. Members of ISO and IEC maintain registers of currently valid International Standards. ISO 261, ISO general-purpose metric screw threads General plan.
