Health and safety in welding and allied processes. Sampling of airborne particles and gases in the operator's breathing zone - Sampling of airborne particles Ingestion-build-105964 Note that the DWDI technique1 Scope This part of ISO 10882 specifies a procedure for sampling airborne particles in the breathing zone of a person who performs welding and allied processes (the operator). It also provides details of relevant standards that specify required characteristics, performance requirements and test methods for workplace air measurement, and augments guidance provided in EN 689 on assessment strategy and measurement strategy. This part of ISO 10882 also
