Health and safety in welding and allied processes - Laboratory method for sampling fume and gases - Part 3: Determination of ozone emission rate during arc welding (ISO 15011-3:2009)

ISO 15011-3:2009 defines a laboratory method for measuring the emission rate of ozone during arc welding, using a hood technique. The method is directed primarily at measuring ozone emission rate when using gas-shielded arc welding processes, but it can also be employed with other processes, e.g. self-shielded flux-cored arc welding, provided that welding can be performed automatically under the hood.

Arbeits- und Gesundheitsschutz beim Schweißen und bei verwandten Verfahren - Laborverfahren zum Sammeln von Rauch und Gasen - Teil 3: Bestimmung der Emissionsrate von Ozon beim Lichtbogenschweißen (ISO 15011-3:2009)

Dieser Teil von ISO 15011 legt Laborverfahren zur Bestimmung der Emissionsrate von Ozon beim Lichtbogen-schweißen mit Hilfe der Haubentechnik fest. Die Methodik ist in erster Linie auf das Messen der Emissions-rate von Ozon beim Schutzgasschweißen ausgerichtet, kann aber auch bei anderen Prozessen, z. B. selbstschützendes Fülldrahtschweißen, verwendet werden, vorausgesetzt, das Schweißen kann unter der Haube automatisch durchgeführt werden.
Das Verfahren kann zur Bewertung der Auswirkungen von Schweißdrähten, Schweißparametern, Verfahren, Schutzgasen, Zusammensetzung des Prüfstücks und Oberflächenbeschaffenheit des Prüfstücks auf die Emis¬sionsrate verwendet werden.

L'ISO 15011-3:2009 définit une méthode de laboratoire pour mesurer le débit d'émission d'ozone lors du soudage à l'arc, en utilisant la technique de la hotte d'aspiration. La méthode est principalement orientée vers le mesurage du débit d'émission d'ozone pour les procédés de soudage à l'arc sous protection gazeuse, mais elle peut également être employée avec d'autres procédés, par exemple le soudage à l'arc avec fil fourré de flux sans gaz, à condition que le soudage puisse être exécuté automatiquement sous la hotte.

Ta del ISO 15011 določa laboratorijsko metodo za merjenje emisij ozona med obločnim varjenjem z uporabo tehnike z varovalnim okrovom. Metoda je namenjena predvsem merjenju emisije ozona med obločnim varjenjem v zaščitnem plinu, lahko pa se uporabi tudi pri drugih postopkih, npr. pri obločnem varjenju s polnjeno žico s samozaščito, pod pogojem, da varjenje poteka avtomatsko pod varovalnim okrovom. Metoda se lahko uporablja za vrednotenje učinkov žic za varjenje, varilnih parametrov, postopkov, zaščitnih plinov, sestave preskusnih kosov in stanja površine preskusnih kosov na emisijo.

ISO 15011-3:2009(E)
Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 15011-3 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee
SC 9, Health and safety.
This second edition cancels and replaces the first edition (15011-3:2002), which has been technically revised.
ISO 15011 consists of the following parts, under the general title Health and safety in welding and allied
processes — Laboratory method for sampling fume and gases:
⎯ Part 1: Determination of fume emission rate during arc welding and collection of fume for analysis
⎯ Part 2: Determination of the emission rates of carbon monoxide (CO), carbon dioxide (CO ), nitrogen
monoxide (NO) and nitrogen dioxide (NO ) during arc welding, cutting and gouging
⎯ Part 3: Determination of ozone emission rate during arc welding
⎯ Part 4: Fume data sheets
⎯ Part 5: Identification of thermal-degradation products generated when welding or cutting through products
composed wholly or partly of organic materials
The following part is under preparation:
⎯ Part 6: Procedure for quantitative determination of fume and gases from resistance spot welding

ISO 15011-3:2009(E)
Introduction
Welding and allied processes generate fume and gases, which, if inhaled, can be harmful to human health.
Knowledge of the composition and the emission rates of the fume and gases can be useful to occupational
health professionals in assessing worker exposure and in determining appropriate control measures.
Absolute exposure is dependent upon factors such as welder position with respect to the plume and draughts
and cannot be predicted from emission rate data. However, in the same work situation, a higher emission rate
is expected to correlate with a higher exposure and a lower emission rate with a lower exposure. Hence,
emission rate data can be used to predict relative changes in exposure that might occur in the workplace
under different welding conditions and to identify measures for reducing such exposure, but they cannot be
used to calculate ventilation requirements.
This part of ISO 15011 defines a method for measuring the emission rate of ozone during arc welding using a
hood technique. The procedure simply prescribes a methodology, leaving selection of the test parameters to
[2]
the user, so that the effects of different variables can be evaluated. Research has shown that differences in
ozone emission rate measured using this technique correlate well with changes in exposure in the workplace.
It is assumed that the executions of the provisions and the interpretation of the results obtained in this part of
ISO 15011 are entrusted to appropriate
