17、ldwide 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 technical committee has been established has the right to be represented on

18、 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 electrotechnical standardization. International Standards are drafted

19、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 committees are circulated to the member bodies for voting. Publication as an International Standar

20、d 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 be held responsible for identifying any or all such patent rights. ISO 13351 was prepared by T

21、echnical 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 It also incorporates the content of ISO 6580:2005, which will be withdrawn following its publication. Licensed Copy: Wang Bin, ISO/EXCHANGE CHIN

For circular

23、 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 interchangeability

24、, 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.

26、ectangular 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 applications. For circular flanges, it provides for three different flange series: one for light-duty casing thickne

27、sses, 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, hole numbers and hole diameters are specified. Flange thickness, as well as internal and external flange diamet

28、ers, 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.

36、ar flanges and the inside lengths of the sides of rectangular flanges. It takes into account 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 diame

37、ter can be related to the inside diameter of the casing, the casing thickness, the size of 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. L

Prac

39、tical experience of satisfactory service, optimum cost of installation and manufacture, as well as dimensional tolerances of production are the most important considerations. The dimensions of circular and rectangular flanges are given in sizes corresponding to nominal diameters from 100 mm to 2 000

40、 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 International Standard are to be applied. 4.2 Circular flanges The number of flange holes is divisible by four to permi

41、t 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 split casing is required. It also allows better access to the fixings on the remote side of a fan in a confined

42、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 interpreted from the next larger R 20 size. In exceptional circumstances, when even smaller increments of fan size are re

43、quired, it is recommended that the R 80 series be used. See Figure 4.
