1 TESTING
TÜV Group performs all the Biowizard Platinum safety cabinets feature classification and verifications as
well as all typetestings (excluding Biowizard Platinum DEF and CW-V models).
All cabinets are adjusted and tested at the factory. Factory settings are giving the best protection for the
products handled on work surface against the contamination and protects the user of health hazardous
substances. Factory test reports are documentied in separate measurement report.
Before first start up of the cabinet (new installation) or if cabinet surroundings has been changed
(e.g changing cabinet location) following installation tests must be performed:
Retention at front aperture:
•Check that manufacturer’s specifications is met
•Airflow rate measurements (inflow and downflow measurement in work chamber)
•Movement of airflow in work chamber (smoke test )
•When needed Kl-Discus test can be done to protect the user at the site. (evaluation of protection
factor)
Filters:
•Filter’s leaktightness test
Product protection:
•Check that manufacturer’s specifications is met
•Airflow rate measurements (inflow and downflow measurement in work chamber)
•Movement of airflow in work chamber (smoke test )
•When needed Kl-Discus test can be done to protect the user at the site. (evaluation of protection
factor)
Cross contamination
•Check that manufacturer’s specifications is met
NOTE! According to the standard EN 12469 all the below mentioned installation
tests must be performed after the cabinet has been installed or every time after
installing or surroundings has been changed before turning it on first time. For
the detailed information from testing, please contact your local Kojair Tech Oy
representative. See www.kojair.com
!
NOTE! Testing should only be performed by service personnel authorized by the
Kojair Tech Oy.
!
NOTE! Cleanwizard Platinum cabinet is not EN 12469 Class II safety cabinet.

1.1 Airflow measurements
Airflow rates are measured either with calibrated anemometer, usually measured in several points or with
calibrated measuring device, which can be used for measuring the airflows in ventilation duct. (see
measurement report the devices used in testing)
1.1.1 Downflow (hotwire anemometer)
Switch on the cabinet. Take hot wire anometer into working chamber. Measuring point should be in
horizontal plane, 50mm to 100mm above the top edge of working aperture. Make measurements over a
period of at least 1 min in each, at least in 8 positions. Measuring positions are locatingin “lines”. Cabinet’s
depth paraller (2 pcs) specified as per following: the rear line locates ¼ of the depth of the working space
forward of the rear wall and the front along the same distance behind the front window. Cabinet’s width
paraller lines (4 pcs) are locating as per following: outermost lineslocates at 1/8 of the width of thecabinet
towards to the middle. The rest of the lines (2 pcs) are divided to ¼ gaps (see picture 1.).
Procedure:
Downflow is measured with hotwire anemometer using following settings:
Hot wire anometer is placed on measuring point. Every measurement takes at least 1 minute. Mean value
is calculated from the measurements. Measurement results and mean value are noted on measurement
report.
Measuring plane = 100mm above the top edge of working aperture

Accteptance criterions:
To achieve product protection, mean downflow velocity must be between 0,25 m/s – 0,50 m/s, and no
individual measurement should differ from the mean value more than ±20 %
Alarm: if the air velocity should exceed the present alarm, an acoustic and visual alarm will be activated,
which can not be muted.

1.1.2 Inflow (using balometer)
Switch on the cabinet. Measure the inflow airflow velocity (l/s) with balometer. Convert table from l/s to
m3/h can be seen below.
Procedure:
Biowizard Platinum cabinet’s inflow air velocity and exhaust air volume is measured with a balometer
using following settings:
Height of the front aperture= 0,2m (normal working height in all models)
Width of the front aperture: Platinum SF, MF, DEF 100 0,907m
Platinum SF, MF, DEF, XL 130 1,212 m
Platinum SF, MF, DEF, XL 170 1,557 m
Platinum SF, MF, DEF, XL 200 1,862 m
Area of the front aperture: Platinum SF, MF, DEF 100 0,181 m2
Platinum SF, MF, DEF, XL 130 0,242 m2
Platinum SF, MF, DEF, XL 170 0,311 m2
Platinum SF, MF, DEF, XL 200 0,373 m2
Minimum inflow air velocity in front aperture = 0,40m/s
(Acoustic and visual alarm is given if inflow velocity is under 0,40 m/s)
Inflow air velocity in front aperture = 0,45m/s (Kojair Tech Oy set point)
Maximum inflow air velocity in front aperture = 0.60m/s
(acoustic and visual alarm given if inflow velocity is more than 0,60 m/s)
Measurer reads from the balometer cabinets exhaust air volume (l/s). Measurer checks that exhaust air
volume is between min. and max exhaust air volume, this way he can be sure that the mean air velocity
in let is ≥0.40 m/s. Min and max.exhaust air volumes and Kojair set point air volumes are listed in table
below.

NOTE! A method for measuring columetric airflow rate in circular exhaust ducts is
given in standard BS 848–1:1997.

1.1.3 Airflow visualization (smoke test)
Purpose of this test is to verify that no recirculated air escapes out of the working space to surrounding
room, and that the replacement air moves through the front grid to the bottom basin of the cabinet without
visible turbulences (see picture 3). Both smoke sticks and smoke generator can be used as a smoke
source.

1.2 Aerosol challenge test of filters
1.2.1 In general
Operate the cabinet and induce the aerosol challenge at a suitable location on the upstream side of HEPA
filters, seals and construction joints to be tested. Ensure that the challenge aerosol concentration is
uniform on the upstream HEPA filter face. Measure average upstream aerosol concentration.
Scan the downstream side of the HEPA filter by passing the aerosol detection probe slightly overlapping
over the entore surface of the HEPA filter.Scan the entire periphery of the filter, the junction between the
filter, and the filter mounting frame. Determine traverse scan rate, sample acquisition time and the actual
particle counts characterizes a leak.
1.2.2 SF, MF and CW-V cabinets:
Down flow filter:
Switch on the aerosol photometer and its pump. Connect the 100% PAO sample pipe to the challenge-
valve. Induce aerosol to the plenum; take the aerosol supply hose under the table top, close to the back
channel (see picture 4) and turn on the aerosol-generator. Calibrate the aerosol photometer after you
have supplied aerosol to the cabinet 1-2 minutes. Scan the downstream side of the filter over the entire
surface. Scan also all filters joints and sealant for leaks (seepicture 6). See below acceptance criteria and
also measurement report, leakage test (DEHS) by EN-12469-00/BS 5726-92.
