European foreword
This document (prEN 16589-2:2025) has been prepared by Technical Committee CEN/TC 332
“Laboratory equipment”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
Introduction
Articulated extraction arms (AEA) are local exhaust devices consisting of capture devices that can be
constructed in a variety of geometric shapes (hoods, nozzles, flat screens etc.) which are connected to or
mounted on extraction arms or arms with flexible joints. They are used for a variety of different
applications in the laboratory where contaminants are encountered. The design of articulated extract
arms for laboratories can differ for different applications.
The ability of capture devices to capture contaminants is subject to a number of factors. These factors are,
extract volume flow, capture velocity, capture hood design, manoeuvrability, position in relation to
emission source, user activity, air speed etc. The capture ability is rapidly decreased with increased
distance to the emission source. Higher air velocity in the opening of the device improves the capture
ability but commonly results in increased noise level and pressure drop of the capture device and extract
arm.
Good information to the user on how to use the device as well as information about the limitations of the
device are essential for safety and health in the laboratories.
Articulated extract arms are useful for very small emission sources or when the emission source is too
large to reasonably be enclosed but has distinct emission points where the pollution might occur like e.g.
a high-performance liquid chromatography (HPLC).
Type test protocols detailed in EN 16589-1 cannot be replicated on site due to the large variances in room
conditions and AEA positioning.
This document therefore provides methods for Commissioning and Testing of AEAs that will provide
practical detail on the function and basic flow characteristics of air at an installed AEA.
The suitability of an AEA to provide effective ventilation at or near a source of contamination is the
responsibility of the customer and will be subject of a risk assessment. Good practice dictates that full
consideration is given to both local regulatory guidance and hygiene practice.
1 Scope
This document applies to test methods designed to be used at the place of installation of the AEA, usually
a laboratory and for various laboratory applications that require local extraction. They are used for
commissioning after installation, for maintenance and for qualification purposes. For certain customer
requirements additional or modified test methods can be necessary.
This document includes product functional performance referring to product standard detailed in
EN 16589-1. Occupational health and safety assessments methods are not included in this document.
This document does not consider performance requirements for the extract air system associated with
the AEA installation and therefore extract system performance is not part of the scope.
This document does not confirm or establish a capture zone of an AEA capture device only the functional
extract capacity and mechanical functions of the AEA.

4 Commissioning
4.1 General
The following test methods are considered to be appropriate for the commissioning test after installation
of an AEA (or multiple AEAs on the same extract system) which has been type tested in accordance with
EN 16589-1 prior to installation. It is the aim of commissioning testing to show the correct supply and
installation of the AEA (or multiple AEA’s on the same extract system) and to check adverse effects of the
AEA location, intended extract position, room airflow, the house extract system and other ventilated
devices on the performance of the installed AEAs connected to the extract system.
Commissioning testing activities shall be carried out using a selection of test methods detailed in this
document.
Consideration should be given to guidance given in CEN/TS 17441 and EN 16589-1:2022, Annex A.
NOTE Consultation between professional parties at system design stage can help to ensure the AEA System
will operate effectively within the environment it is intended. Consultation at commissioning stage can help to
ensure that all parts of the extract air and AEA system work effectively and without impact on other connected
devices when tested as a complete system.
4.2 Inspections
4.2.1 General
The following items, 4.2.2 and 4.2.3, shall be proven by inspection.
4.2.2 Review of system as installed
It is the customers responsibility to ensure that the extract air system is suitable for AEA devices fitted.
Verify that extract air system has been commissioned according to AEA requirements detailed by the AEA
manufacturer.
Check and record design parameters such as:
— transition detail between AEA assembly and house extract;
— pressure requirement;
— design volume flow;
— concurrency / diversity profiles;
— temperature range.
4.2.3 Visual inspection
A visual inspection of the assembly and observance of installation shall be carried out in accordance with
manufacturer’s instructions (such as manual or datasheet supplied with system).
— System labelling (identification and conformity label);
— Manufactures’ identification.
4.2.4 Conformity
Review manufacturer’s documentation to prove conformity to EN 16589-1.
4.2.5 Correct mechanical assembly and operation
Check mechanical assembly and stability of AEA in situ referring to system manual or specification
document.
— Check for system completeness in accordance with manufacturers documentation.
— Identify connection arrangement to extract system and mounting detail.
— Where possible, check fixture to extract air system is secure.
— Check AEA achieves maximum and minimum reach as specified by the manufacturer.
— Check the hold stability at maximum and minimum reach positions – AEA to hold position without
additional support.
— Inspect all movable parts (bends, retention sections such as gas struts and springs).
— Check for damage to any part of the AEA device.
4.2.6 Alarms and indicators
Identify alarm / indicator type (visual indication, pressure or flow) and location.
— Check that indicator of the airflow or the air pressure is installed on the AEA.
— Check alarm associated with this indicator is installed.
— Check function is in accordance with EN 16589-1.
4.2.7 Capture zone indicator
If capture zone indicator is fitted, check indicator works as described in user manual.
4.3 Testing
4.3.1 General
The purpose of the following test protocols is to establish a set of test results that will establish that an
AEA is operating within manufactures specifications in the position or positions in which the AEA will be
used.
Another aim is to obtain reference values for comparison in subsequent routine tests.
Testing shall be carried out under the conditions of the expected configuration and use (single or multiple
AEAs in operation at any one time). For example, where there are multiple AEAs expected to be used at
the same time then testing shall take place with those multiple AEAs in operation.
4.3.2 Test equipment
The following test equipment shall be used:
— Low velocity anemometer, suitable for measuring air velocities in the range 0,05 m/s to 3 m/s with
an accuracy of 0,02 m/s ± 5 % of the reading or better, with a response time less than or equal to 1 s
and having a calibration that is traceable to national standards.
— Flow measuring device, or other suitable device, capable of measuring air flow velocity inside ducts
in accordance with EN 16211 with a maximum uncertainty of ± 5 % and having a calibration that is
