DS DSEN SO 15011-2 2009-NOV-20 Health and safety n weldng and alled processes - Laboratory method for samplng fume and gases - Part 2 Determnaton of the emsson rates of carbon monoxde CO carbon doxde CO2 ntrogen monoxde NO and ntrogen doxde NO2 durng arc weldng cuttng and gougng
This part of ISO 15011 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.
