28、na, Sun Nov 19 08:44:08 GMT+00:00 2006, Uncontrolled Copy, (c) BSI iv 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 techni
29、cal 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 w
30、ith 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 3. Draft International Standards adopted by the technical committees are circulated to th
31、e member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard ISO 9906 was prepared by Technical Committee ISO/TC 115, Pumps, Subcommittee SC 2, Methods of measuring and testing. This first edition
32、of ISO 9906 cancels and replaces ISO 2548:1975 and ISO 3555:1977, which have been combined and technically revised (see Introduction). Annexes A, B and C form a normative part of this International Standard. Annexes D to K are for information only. EN ISO 9906:1999 Licensed Copy: sheffieldun sheffie
33、ldun, na, Sun Nov 19 08:44:08 GMT+00:00 2006, Uncontrolled Copy, (c) BSI Introduction This International Standard combines and replaces the former acceptance test standards ISO 3555:1977 (corresponding to grade 1 of this International Standard) and ISO 2548:1975 (corresponding to grade 2 of this Int
34、ernational Standard), but there is an important change in the verification of guarantees, because the uncertainty of measurement must not influence the acceptability of a pump and the tolerances are due to constructional differences only. New tolerance factors have been introduced to ensure as far a
35、s possible that a pump which was acceptable under the previous International Standards (ISO 2548 and/or ISO 3555) would also be acceptable under this International Standard. Contrary to this International Standard, ISO 5198 is not to be understood as an acceptance test code. It gives guidance for me
36、asurements of very high accuracy and for the thermodynamic method for direct measurement of efficiencies, but it does not recommend verification of guarantees. Terms used in this International Standard such as “guarantee” or “acceptance” should be understood in a technical but not in a legal sense.
37、The term “guarantee” therefore specifies values for checking purposes determined in the contract, but does not say anything about the rights or duties arising, if these values are not reached or fulfilled. The term “acceptance” does not have any legal meaning here, either. Therefore, an acceptance t
38、est carried out successfully alone does not represent an “acceptance” in the legal sense.

39、ntrolled Copy, (c) BSI 1 Rotodynamic pumps Hydraulic performance acceptance tests Grades 1 and 2 1 Scope This International Standard specifies hydraulic performance tests for acceptance of rotodynamic pumps (centrifugal, mixed flow and axial pumps, hereinafter simply designated as “pumps”). It is ap
40、plicable to pumps of any size and to any pumped liquids behaving as clean cold water (such as defined in 5.4.5.2). It is neither concerned with the structural details of the pump nor with the mechanical properties of their components. This International Standard contains two grades of accuracy of me
41、asurement: grade 1 for higher accuracy, and grade 2 for lower accuracy. These grades include different values for tolerance factors, for allowable fluctuations and uncertainties of measurement. For pumps produced in series with selection made from typical performance curves and for pumps a with powe
42、r input of less than 10 kW, see annex A for higher tolerance factors. This International Standard is applicable both to a pump itself without any fittings and to a combination of a pump associated with all or part of its upstream and/or downstream fittings. 2 Normative references The following norma
43、tive documents contain provisions which, through reference in this text, constitute provisions of this International Standard.
