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 technical
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 with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical 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.
International Standard ISO 13350 was prepared by Technical Committee ISO/TC 117, Industrial fans.
Annexes A, B, C and D of this International Standard are for information only.

Introduction
The need for this new standard has been evident for some time. The use of the so-called jet fan to assist in
controlling the quality of air in vehicle and train tunnels has become increasingly popular. The longitudinal method of
ventilation can show advantages in initial cost and running cost compared to alternative systems, and smoke control
in emergency conditions can be readily provided. At present, there is no published national or international standard
for the performance testing of jet fans.
This International Standard, which forms part of the ISO/TC 117 series of fan standards, deals with the
determination of those performance criteria essential to the correct application 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.

Industrial fans — Performance testing of jet fans
1 Scope
This International Standard 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.
The test procedures described in this International Standard relate to laboratory conditions. The measurement of
performance under on-site conditions is not included.

3 Definitions
For the purposes of this International Standard, the definitions given in ISO 13349, ISO 5801 and the following
apply.
3.1
effective fan dynamic pressure
p
d
conventional quantity representative of the dynamic component of the fan output, calculated, in the particular case
of a jet fan, from the effective fan outlet velocity and the inlet density
NOTE The effective fan dynamic pressure will not be the same as the average of the dynamic pressures across the
section because it excludes from consideration that part of the dynamic energy flux which is due only to departures from
uniform axial velocity distribution.
3.2
effective fan outlet area
A
eff
in the particular case of a jet fan, outlet area with deductions for motors, fairings or other obstructions
NOTE 1 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 2 If the fan has a silencer without centrebody [see figure 1 b)], 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 If the centrebody (motor or silencer core) does not extend to the outlet plane, 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.

3.3
effective fan outlet velocity
v
eff
calculated from the thrust, the inlet density and the effective fan outlet area as detailed in 11.2
3.4
fan outlet velocity
in the particular case of a jet fan, inlet volume flow divided by effective fan outlet area, A

3.5
fan air power
conventional power output; in the particular case of a jet fan, product of inlet volume flow and effective fan dynamic
pressure

3.6
impeller tip speed
u
peripheral speed of the impeller blade tips
3.7
thrust
T , T
m c
fan thrust measured or calculated in accordance with this International Standard
3.8
thrust/power ratio
r
t
thrust divided by impeller power
NOTE An alternative definition of thrust/power ratio which has sometimes been used: thrust divided by motor input power.
This definition is deprecated, as it will vary according to the motor manufacturer used. It also results in a lower value, as the
motor losses are included.
3.9
fan guard
guard designed to prevent the ingestion of relatively large foreign bodies, such as drink cans, and sometimes fitted
to the inlet and outlet of jet fans
NOTE Guards can have a marked effect on the thrust performance and noise level. Where they are sp
