Health and safety in welding and allied processes - Requirements, testing and marking of equipment for air filtration - Part 2 : determination of the minimum air volume flow rate of captor hoods and nozzles

ISO 15012-2:2008 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.ISO 15012-2:2008 also specifies the test data to be marked on the capture devices.

Health and safety in welding and allied processes - Equipment for capture and separation of welding fume - Part 4 : determination of the minimum air volume flow rate of capture devices

This document specifies two methods for establishing the minimum air volume flow rate. One method is dedicated for use with captor hoods, nozzles and slot nozzles with a ratio of slot length to hose diameter of 8:1 or less. The other method is dedicated for use with on-gun extraction devices. These methods are not applicable to down draught tables.
