15、iv ISO 2009 All rights reservedForeword 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 intere
16、sted 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 International Electrotechnical
17、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 Standards. Draft International Standards adopted by the tec
18、hnical 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 this document may be the subject of patent rights. ISO
19、 shall not be held responsible for identifying any or all such patent rights. ISO 13351 was prepared by Technical Committee ISO/TC 117, Fans. This second edition cancels and replaces the first edition (ISO 13351:1996), of which it constitutes a minor revision. It also incorporates the content of ISO
20、 6580:2005, which will be withdrawn following its publication. BS EN ISO 13351:2009ISO 13351:2009(E) ISO 2009 All rights reserved vIntroduction This International Standard gives dimensional details of circular and rectangular flanges of fans in addition to specifying the fan size designation. For ci
21、rcular flanges, the values specified in ISO 6580 have been retained for light-duty fans, in parallel with those values given in Tables 3 and 4 for medium- and heavy-duty fans. While it does not constrain the manufacturers choice of flange details, this International Standard facilitates interchangea
22、bility, thereby helping to reduce technical barriers to trade. Throughout this International Standard, the principal dimensions are based on the rounded values of preferred numbers given in ISO 497.

23、reserved 1Fans Dimensions 1 Scope This International Standard specifies the dimensions of the circular and rectangular flanges of general-purpose fans, as well as the fan size designations. It is not applicable to cross-flow fans or to fan appliances used for individual household or similar applicat
24、ions. For circular flanges, it provides for three different flange series: one for light-duty casing thicknesses, another for medium-duty fans and the third for heavy-duty fans as used on sea-going vessels or in heavy industry. In order not to restrict fan design unduly, only the pitch diameter, hol
25、e numbers and hole diameters are specified. Flange thickness, as well as internal and external flange diameters, may be chosen freely within the limits of good engineering practice. 2 Normative references The following referenced documents are indispensable for the application of this document.

32、ller Mixed-flow fan 4 Requirements 4.1 General This International Standard adopts the Renard R 20 series according to ISO 497 as the nominal dimensions for impeller tip diameters, the inside diameters of circular flanges and the inside lengths of the sides of rectangular flanges. It takes into accou
33、nt the maximum casing thicknesses likely to be used for general-purpose fans, as well as typical manufacturing tolerances representative of engineering “good practice”. The smallest practical pitch circle diameter can be related to the inside diameter of the casing, the casing thickness, the size of
34、 the weld fillet or bend radius at the junction of the flange and the casing, and the normal washer diameter. Light-duty circular flanges might not be suitable for the use of open-ended spanners in all cases. BS EN ISO 13351:2009ISO 13351:2009(E) 4 ISO 2009 All rights reservedThis International Stan
35、dard accepts that the number and diameter of bolts or screws cannot be established on a theoretical basis. Practical experience of satisfactory service, optimum cost of installation and manufacture, as well as dimensional tolerances of production are the most important considerations. The dimensions
36、 of circular and rectangular flanges are given in sizes corresponding to nominal diameters from 100 mm to 2 000 mm. In the smaller sizes (below about 200 mm) flange details may be determined by the customers specification. However, where this is not the case, then the specifications of this Internat
37、ional Standard are to be applied. 4.2 Circular flanges The number of flange holes is divisible by four to permit the orientation of cylindrical cased fans at positions of 90. The holes are disposed equally on each side of the centrelines of the fan. This permits a flange to be divided in half if a s
38、plit casing is required. It also allows better access to the fixings on the remote side of a fan in a confined installation. When an intermediate fan size is required, the R 40 series in accordance with ISO 3 shall be used to obtain the nominal inside diameter. The flange details shall be interprete
39、d from the next larger R 20 size. In exceptional circumstances, when even smaller increments of fan size are required, it is recommended that the R 80 series be used. See Figure 4.
