This document covers health and safety in welding and allied processes. It specifies requirements for determination of the emission rate and chemical composition of welding fume in order to prepare fume data sheets. It applies to all filler materials used for joining or surfacing by arc welding using a manual, partly mechanized or fully automatic process, depositing unalloyed steel, alloyed steel and non ferrous alloys. Manual metal arc welding, gas shielded metal arc welding with solid wires, metal cored and flux cored wires and arc welding with self shielded flux cored wires are included within the scope of this document.
