Introduction
Articulated extraction arms are local exhaust devices consisting of capture devices that may 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 may differ for different applications.
The ability of articulated extract arms to effectively capture contaminants is subject to a number of
factors. These factors include extract volume flow, capture velocity, capture hood design,
manoeuvrability, position in relation to emission source, user activity, and room conditions.
Due to the fact that the capture efficiency can be affected dramatically by a change in any of the above
conditions, articulated extract arms are only useful for very small pollution sources, or when the pollution
source cannot be reasonably enclosed and has distinct points where the pollution might occur.
The objective of this document is to give information relevant to articulated extraction arms and to
specify type test methods for articulated extraction arms. This document offers assistance in the testing
of articulated extraction arms and in the drafting of user information. It is intended to contribute towards
mutual understanding amongst manufacturers, laboratory designers, users and health and safety
authorities.
The performance data obtained onsite will not necessarily reflect the type test data due to environmental
influences. Prior to use, the performance of the device needs to be assessed to ensure it complies with the
performance benchmarks specified in the risk assessment. It is the responsibility of the user that
appropriate commissioning has been carried out. The extent of the commissioning testing should be
based on a risk assessment.
It is intended to work on further parts of this standard series dealing with commissioning and installation
and on-site testing.

1 Scope
This document is applicable to articulated extraction arms used as a local exhaust device in laboratories
and comprised of a specific capture device (receiving, enclosing or capture hood, nozzle or flat screen)
connected to ducting to move air from the capture device to discharge.
This document is a product standard. This document covers product performance type test methods.
Occupational health and safety assessments methods are not included in this document.
This document specifies:
• a method to assess the three-dimensional capture zone of an articulated extract arms;
• a method for assessing the isothermal and diffusive emission release capture efficiency of articulated
extract arms and robustness to a challenge of air disturbance directly in front of and in close
proximity to the capture hood and release source positioned on a table;
• a method for establishing the reachable, three-dimensional workspace of articulated extract arms;
• a method for measuring the pressure drop and noise level of articulated extract arms;
• instructions for marking the devices and recommended information in the product manual;
• guidance for use describing the limitations of articulated extract arms for different airflow rates;
• guidance on selection, installation, commissioning, and testing of articulated extract arms and the
associated local exhaust ventilation systems.
The test procedure for capture efficiency and the guidance included in Annex A and B does not apply to
particle sources or point sources which release contaminants with initial velocity of above 0,5 m/s due
to temperature, pressure release, work process or similar.
The scope does not include filtration requirements and impact of fully or partly recirculated airflow
extracted by an articu
