Health and safety in welding and allied processes - Laboratory method for sampling fume and gases generated by arc welding - Part 2: Determination of emission rates of gases, except ozone

ISO 15011-2:2003 provides guidance on the determination of emission rates of gases generated by arc welding using a fume box technique. It describes the test principle, gives a possible fume box arrangement and considers methods for sampling and analysis. The following gases that can be produced during arc welding are covered: - carbon monoxide (CO); - carbon dioxide (CO2); - nitrogen oxide (NO); - nitrogen dioxide (NO2). The fume box described in this International Standard may also be used for the determination of organic gases produced in the arc welding of coated metals, e.g. primed, painted or plastic coated material.
