Foreword
This document (prEN 16282-9:2011) has been prepared by Technical Committee CEN/TC 156 “Ventilation for
buildings”, the secretariat of which is held by BSI.
This document is currently submitted to the CEN Enquiry.
Basic intention of this document is to evaluate extraction system components with regards to the calculation
given in prEN 16282 – 1. A factor X should be added to the calculation formula of V in 10.3 of prEN 16282 –
th
1. This factor is to be set at 0,6 (default factor used in order to ensure the safety of a even very bad designed
system) if a manufacturer of components chose not to carry out the tests of this standard prEN 16282 – 9.
With the test of this part 9 it can be shown that an extraction system is able to work properly with the air flow
calculated according to prEN16282 – 1 or even better. Clause 10 of this part shall contain the calculation of
the above described factor X.
The document is drafted for extraction systems in general. Special information / tests for hoods, ceilings or
other extraction systems will / can be added in annexes.
 Part 1: General requirements including calculation method
 Part 2: Kitchen ventilation hoods – Design and safety requirements
 Part 3: Kitchen ventilation ceilings – Design and safety requirements
 Part 4: Air inlets and outlets – Design and safety requirements
 Part 5: Air duct – Design and dimensioning
 Part 6: Aerosol separators – Design and safety requirements
 Part 7: Installation and use of fixed fire suppression systems
 Part 8: Installation for treatment of cooking fumes – Requirements and tests
 Part 9: Capture and containment performance of extraction systems for commercial kitchen – test
methods
1 Scope
This standard is intended to measure the capture and containment performance of ventilation extraction
systems during simulated cooking conditions of an extraction device installed over standardized cooking
appliance thermal plume challenges under specified appliance configurations and positioning, in kitchens and
other companies processing foodstuffs intended for commercial use.
This test method describes flow visualization techniques that are used to determine the threshold of capture
and containment capture and containment for non cooking and specified heavy cooking conditions. The
threshold of capture and containment can be used to estimate minimum flow rates for hood/appliance
systems.
The test procedure determines static pressure differential after the exhaust collar of the hood.
It does not apply to household kitchens.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1 Aspect ratio
Ratio of length to width of an opening or grill.
3.2 Energy rate
The average rate at which an appliance consumes energy during a specified condition (for example, non
cooking or cooking).
3.3 Cooking energy consumption rate
The average rate of energy consumed by the appliance(s) during cooking.
3.4 Fan and control energy rate
The average rate of energy consumed by fans, controls, or other accessories associated with cooking
appliance(s). This energy rate is an average during preheat, non cooking, and cooking tests.
3.5 Product performance: Capture and containment
The ability of the ventilation system to capture and contain grease-laden cooking vapors, convective heat, and
other products of cooking processes. The extraction system capture refers to the products getting into the
extraction system reservoir from the area under the extraction system while containment refers to the products
staying in the extraction system reservoir.
3.6 Energy consumption rate during non-cooking process
The average rate at which an appliance consumes energy while it is non cooking, holding, or ready-to-cook, at
4

---------------------- Page: 6 ----------------------
oSIST prEN 16282-9:2012
prEN 16282-9:2011 (E)
a temperature.
3.7 Measured energy input rate
The maximum or peak rate at which an appliance consumes energy measured during appliance preheat, that
is, measured during the period of operation when all gas burners or electric heating elements are set to the
highest setting.
3.8 Rated energy input rate
The maximum or peak rate at which an appliance consumes energy as rated by the manufacturer and
specified on the appliance nameplate.
3.9 Compensating air
Air deliberately supplied into the space (test room), and to the exhaust hood to compensate for the air, vapor,
and contaminants being expelled (also referred to as make-up air). Can be dedicated make-up air directed
locally in the vicinity of the hood, transfer air, or a combination.
3.10 Make-up air
The part of compensating air which is supplied through the hood, generally in the front face. This doesn’t’
include airflows supplied directly into the hood for captation purpose.
3.10.1 Integrated hood plenums
3.10.1.1
Air curtain supply, n - compensating air that it is introduced vertically downward, typically from the front edge
of the hood.
3.10.1.2
Backwall supply, n - compensating air delivered behind and below the cooking appliance line, typically through
a ducted wall plenum. Sometimes referred to as rear supply.
3.10.1.3
Front face supply, n - compensating air that it is introduced into the kitchen space through the front face of the
hood.
3.10.1.4
Internal supply, n-compensating air delivered directly to the interior of an exhaust hood such that it is
exhausted without entering the occupied space. Sometimes referred to as short-circuit supply.
3.11 Threshold of capture and containment
The conditions of hood operation in which minimum flow rates are just sufficient to capture and contain the
products generated by the appliance(s). In this context, two minimum capture and containment points can be
determined, one for appliance non cooking condition, and the other for heavy-load cooking condition.
3.12 Simulated thermal plume challenge
An appliance plume that duplicates the actual cooking effluent and/or thermal plume from an appliance or line
