BS EN ISO 21904-3:2018 defines a laboratory method for measuring the welding fume capture efficiency of ontorch
extraction systems. The procedure only prescribes a methodology, leaving selection of the test
parameters to the user, so that the effect of different variables can be evaluated.
It is applicable to integrated on-torch systems and to systems where a discrete extraction system
is attached to the welding torch close to the arc area. The methodology is suitable for use with all
continuous wire welding processes, all material types and all welding parameters.
The method can be used to evaluate the effects of variables such as extraction flow rate, extract nozzle
position, shielding gas flow rate, welding geometry, welding torch angle, fume emission rate, etc., on
capture efficiency.
