scope:

This Technical Specification specifies safety requirements applicable to a) thermal plasma torch systems: - arc plasma systems, - inductive plasma systems; b) installations using plasma torch systems: - spraying equipment, - solid, liquid and gaseous charge heating and thermochemical treatment equipment. For both plasma torch systems and installations using plasma torch systems, this specification determines safety requirements for all components, including the electrical equipment, the cooling circuits, the gas supply circuits, the furnace or reactor and more generally, all other equipment associated with the use of the furnace or reactor. Safety and construction requirements for plasma torches for welding, cutting and allied processes are specified in IEC 60974-7.
