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); German version EN ISO 15011-3:2009
This International standard defines a laboratory method for measuring the emission rate of ozone, during arc welding, using a hood technique. The methodology 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. selfshielded tubular-cored arc welding, providing that welding can be performed automatically under the hood. Emission rate testing can be used to evaluate the effects of welding parameters, processes, shielding gases, consumable wires etc on ozone emission rate and hence to predict, qualitatively, relative changes in exposure that will occur under the same work situations. Absolute exposure values are dependent upon other factors such as welder position with respect to the plume and draughts and cannot be predicted from emission rate values.
