Standardization of occupational health and safety in welding and related processes. This includes requirements on machines, equipment and devices and their connections in order to:

  • minimize, detect, remove and separate hazardous substances resulting from welding and allied processes;
  • protect personnel against hazards in the welding environment (e.g. radiation, noise, vibration, mechanical, optical, thermal hazards);

It also includes measuring and testing procedures e.g. extraction efficiency.
