Equipment for commercial kitchens - Components for ventilation in commercial kitchens - Part 9: Capture and containment performance of extraction systems; test methods

This European Standard specifies the requirements for the test methods for the capture and containment performance of extraction systems in commercial kitchens, including the technical safety, ergonomic and hygienic features.
This European Standard is applicable to ventilation systems in commercial kitchens, associated areas and other installations processing foodstuffs intended for commercial use. Kitchens and associated areas are special rooms in which meals are prepared, and where tableware and equipment is washed and cleaned and food is stored.
This European Standard is not applicable is not applicable to kitchen ventilation systems that are used in domestic kitchens.
Unless otherwise specified, the requirements of this standard shall be checked by way of inspection and/or measurement.
NOTE   Please note the possible existence of additional or alternative local national regulations on installation, appliance requirements and inspection, maintenance and operation.
The test method in accordance with this standard describes flow visualization techniques that are used to determine the threshold of 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.
This European standard does not address safety concerns, if any, associated with its use.

Foreword

This document (prEN 16282-9:2014) 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 e should be added to the formula (8) in 10.3 of prEN 16282–1. This factor

eff

is to be set at 1,0 default factor used in order to ensure the safety of even a badly designed system if a

manufacturer of components chose not to carry out the tests of this standard prEN 16282–9. With the test in

this Part 9 it can be shown that an extraction system is able to work properly with the airflow calculated in

accordance with prEN 16282–1 or better. Clause 9.1 of this part contains the calculation of the above

described factor e .
eff

The document is drafted for extraction systems in general. Special information/tests for hoods, ceilings or

other extraction systems can be added in annexes. The activities of CEN/TC 156/WG 14, cover the

calculation of the air volume and the design and testing of major components of ventilation equipment for

commercial kitchens.
The structure of the standard series is as follows:

1 Scope

This European Standard specifies the requirements for the test methods for the capture and containment

performance of extraction systems in commercial kitchens, including the technical safety, ergonomic and

hygienic features.

This European Standard is applicable to ventilation systems in commercial kitchens, associated areas and

other installations processing foodstuffs intended for commercial use. Kitchens and associated areas are

special rooms in which meals are prepared, and where tableware and equipment is washed and cleaned and

food is stored.

This European Standard is not applicable to kitchen ventilation systems that are used in domestic kitchens.

Unless otherwise specified, the requirements of this standard shall be checked by way of inspection and/or

measurement.

NOTE Please note the possible existence of additional or alternative local national regulations on installation,

appliance requirements and inspection, maintenance and operation.

The test method in accordance with this standard describes flow visualization techniques that are used to

determine the threshold of 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.

This European standard does not address safety concerns, if any, associated with its use.

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
average rate at which an appliance consumes energy during a specified condition
Note 1 to entry: For example, non-cooking or cooking.
3.3
cooking energy consumption rate
average rate of energy consumed by the appliance(s) during cooking
3.4
fan and control energy rate

average rate of energy consumed by fans, controls, or other accessories associated with cooking appliance(s)

Note 1 to entry: This energy rate is an average during preheat, non-cooking, and cooking tests.

3.5
product performance: Capture and containment

ability of the ventilation system to capture and contain grease-laden cooking vapours, convective heat, and

other products of cooking processes

Note 1 to entry: The exhaust 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

average rate at which an appliance consumes energy while it is non-cooking, holding, or ready-to-cook, at a

temperature
3.7
measured energy input rate

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

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, vapour,

and contaminants being expelled

Note 1 to entry: This can be dedicated make-up air directed locally in the vicinity of the hood, transfer air, or a

combination.

conditions of hood operation in which minimum flow rates are just sufficient to capture and contain the

products generated by the appliance(s)

Note 1 to entry: 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

of appliances
