21、n 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 technical committee has been established has
22、 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 electrotechnical standardization.The pr
23、ocedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the edito
24、rial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). Attention is drawn to the possibility that some of the elements of this document can be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent righ
25、ts identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).

The main changes are the following: General (dated references on standards updated, e.g. ISO 5801:2007); Clause 2 “Normative references” (references supplemented a

29、 and abbreviated terms” (supplemented and updated); 6.4 “Input power” (correction for density); 7.1 “Determination of thrust” (correction for density); 7.4 “Test procedures” (change of recommended calibration intervals); Figure 7 “Thrust measuring enclosure” (modified by reducing the minimum distanc

34、a new edition of ISO 13350 has been evident for some time. The use of the so-called jet fan to assist in the control of quality of air in vehicle and train tunnels has become increasingly popular. Longitudinal methods of ventilation can show advantages in both capital cost and running cost compared
35、to alternative systems. Smoke and pollution control in emergency conditions can be readily provided. Jet fans can also be used for ventilation and smoke control in enclosed car parks.This International Standard deals with the determination of those performance criteria essential to the correct appli
36、cation of jet fans. In describing the test and rating procedures, numerous references are made to ISO 5801 as well as to other relevant International Standards. ISO 2015 All rights reserved viiBS EN ISO 13350:2015BS EN ISO 13350:2015Fans Performance testing of jet fans1 ScopeThis International Stand
37、ard deals with the determination of those technical characteristics needed to describe all aspects of the performance of jet fans as defined in ISO 13349. It does not cover those fans designed for ducted applications, nor those designed solely for air circulation, e.g. ceiling fans and table fans.Th
38、e test procedures described in this International Standard relate to laboratory conditions. The measurement of performance under on-site conditions is not included.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable fo
39、r its application. For dated references, only the edition cited applies.

46、extremity of the air-moving deviceNote 1 to entry: Gross fan outlet area is, by convention, taken as the gross area in the outlet plane inside the casing or duct or silencer, (see Figure 1) without taken into account any obstructions inside the fan outlet.3.2.2effective fan outlet areaAeffoutlet are
47、a with deductions for motors, fairings, or other obstructions (in the particular case of a jet fan)Note 1 to entry: If the silencer centrebody reaches the outlet plane of the fan, then, the effective fan outlet area is defined as the annulus area at the fan outlet plane, as shown in Figure 1a).Note
48、2 to entry: If the fan has a silencer without centrebody see Figure 1b), the effective fan outlet area will be close to the cross- sectional area inside the silencer in order to clear any exit bellmouth form.Note 3 to entry: If the centrebody (motor or silencer core) does not extend to the outlet pl
49、ane, the effective fan outlet area will approach the annulus area between the casing and the motor, but with some increase, as defined in Figure 1c), for the distance between the centrebody and the outlet. Where the motor is on the upstream side, Figure 1c) is applied to the impeller hub rather than the motor, as illustrated.Note 4 to entry: For comparisons within the scope of research and development, alternative definitions have been used with some success.Figure 1 Gross and effective fan outlet areas3.3eff
