Health and safety in welding and allied processes. Equipment for capture and separation of welding fume - Determination of the minimum air volume flow rate of capture devices Ingestion-build-221493 Due to the spatial homogeneityWhat is ISO 21904 4 about? ISO 21904 4 is an international standard series that covers the health and safety in welding and allied processes. ISO 21904 4 is the fourth part of a multi series standard that 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 to using
