scope:

This standard specifies safety requirements applicable to arc plasma heating installations using hand-operated torches or mechanically-operated torches, for example for welding, cutting or spraying. This standard also specifies general safety requirements for arc plasma furnace installations other than the power supply: that is, the furnace itself, its foundation and structure, cooling circuits, gas supply circuits, electrical equipment from power supply onwards, furnace handling and control gear, and other equipment associated with the use of the furnace.
