NF EN ISO 15011-3
Health and safety in welding and allied processes - Laboratory method for sampling fume and gases generated by arc welding - Part 3 : determination of ozone concentration using fixed point measurements
ISO 15011-3 defines a laboratory method for evaluating ozone emissions generated during arc welding by measuring ozone concentrations at fixed points around a stationary welding arc. The results may be used to compare the effect of welding parameters, processes, etc. on ozone generation and hence to predict changes in workplace exposure under similar working conditions.

<p>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.</p>
