BS EN ISO 15011-2:2009 Health and safety in welding and allied processes. Laboratory method for sampling fume and gases. Determination of the emission rates of carbon monoxide (CO), carbon dioxide (CO2), nitrogen monoxide (NO) and nitrogen dioxide (NO2) during arc welding, cutting and gouging

Welding and related processes generate fumes and gases, which can be harmful if inhaled. Knowledge of the composition and the emission rate of the fume and gases can be useful to occupational health professionals in assessing worker exposure and in determining appropriate control measures.

BS EN ISO 15011-2 specifies a method for measuring the emission rate of carbon monoxide (CO), carbon dioxide (CO2), nitrogen monoxide (NO) and nitrogen dioxide (NO2) during arc welding, cutting and gouging using a hood technique. The procedure simply prescribes a methodology, leaving selection of the test parameters to the user, so that the effect of different variables can be evaluated.

It is assumed that the executions of the provisions and the interpretation of the results obtained in this part of BS EN ISO 15011-2are entrusted to appropriately qualified and experienced people.

BS EN ISO 15011-2 defines laboratory methods for measuring the emission rates of carbon monoxide (CO), carbon dioxide (CO2), nitrogen monoxide (NO) and nitrogen dioxide (NO2) generated during arc welding, cutting and gouging, using a hood technique. The methodology is suitable for use with all open arc welding processes, cutting and gouging but different designs of hood are used depending on the process and whether or not  it can be conducted automatically.

The method can be used to evaluate the effects of welding wires, welding parameters, processes, shielding gases, test piece composition and test piece surface condition on emission rate.
