- Part 2: Determination of the minimum air volume flow rate of
captor hoods and nozzles (ISO 15012-2:2008)
This part of ISO 15012 specifies a method for establishing the minimum air volume flow rate required for
captor hoods and nozzles to effectively capture fume and gases from welding and allied processes. The
method can be used with capture devices of any aspect ratio and cross-sectional area, but it is not applicable
to on-gun extraction systems and down draught tables.
This part of ISO 15012 also specifies the test data to be marked on the capture devices.
