25、d 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 technica

26、l 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 ele

27、ctrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to th

28、e 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 International Standard may be the subject of patent rights. ISO shall not be held respo

29、nsible for identifying any or all such patent rights. International Standard ISO 5199 was prepared by Technical Committee ISO/TC 115, Pumps, Subcommittee SC 1, Dimensions and technical specifications of pumps. This second edition cancels and replaces the first edition (ISO 5199:1986), which has been

30、 technically revised. Annexes A, C and D form a normative part of this International Standard. Annexes B, E, F, G and H are for information only. ENISO5199:2002vi Introduction This International Standard is one of a set dealing with technical specifications of centrifugal pumps; they are designated

31、as Classes I, II and III. Class I comprises the most severe and Class III the least severe requirements. The selection of the class to be used is in accordance with the technical requirements for the application for which the pump is intended. The class chosen should be agreed between the purchaser

32、and supplier. Furthermore, additional safety requirements concerning the field of application should be taken into account. However, it is not possible to standardize the class of technical requirements for centrifugal pumps for a certain field of application, because each field of application compr

33、ises different requirements. All classes (I, II and III) can be used in accordance to the different requirements of the pump application. So it may happen that pumps built in accordance with Classes I, II and III may work beside one another in the one plant. Further requirements covering specific ap

34、plications or industries may be dealt with in separate standards. Criteria for the selection of the required class of a pump for a certain application may include reliability, required operating life, operating conditions, environmental conditions, and local ambient conditions. Cross-references in b

35、oldface and the checklist in annex H indicate where a decision may be required by the purchaser, or where agreement is required between the purchaser and the manufacturer/supplier.

36、ifugal pumps Class II 1 Scope 1.1 This International Standard specifies the requirements for Class II centrifugal pumps of single-stage, multistage, horizontal or vertical construction, with any drive and any installation for general application. Pumps used in the chemical process industries (e.g. t

37、hose conforming to ISO 2858) are typical of those covered by this International Standard. 1.2 This International Standard includes design features concerned with installation, maintenance and safety for these pumps including baseplate, couplings and auxiliary piping, but it does not specify any requ

38、irements for the driver other than those related to its rated power output. 1.3 Where application of this International Standard has been called for and requires a specific design feature, alternative designs may be offered which meet the intent of this International Standard provided that the alter

39、native is described in detail. Pumps not complying with all the requirements of this International Standard may be offered for consideration provided that all deviations are stated. 2 Normative references The following normative documents contain provisions which, through reference in this text, con

40、stitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of 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 ed
