This standard specifies requirements for the classification of gases and gas mixtures used in fusion welding and allied processes including, but are not limited to: ? tungsten arc welding (Process 141 in accordance with ISO 4063); - gas shielded metal arc welding (Process 13 in accordance with ISO 4063) including: o metal inert gas welding (Process 131), o metal active gas welding (Process 135), o tubular cored metal arc welding with active gas shield (Process 136), o tubular cored metal arc welding with inert gas shield (Process 137); - plasma arc welding (Process 15 in accordance with ISO 4063); - plasma arc cutting (Process 83 in accordance with ISO 4063); - laser welding (Process 52 in accordance with ISO 4063); - laser cutting (Process 84 in accordance with ISO 4063); - arc braze welding (Process 972 in accordance with ISO 4063). The purpose of this standard is to classify and designate shielding, backing, process and assist gases in accordance with their chemical properties and metallurgical behaviour as the basis for correct selection by the user and to simplify the possible approval procedures. Gas purities and mixing tolerances are specified as delivered by the supplier (manufacturer) and not at the point of use. Gases or gas mixtures may be supplied in either liquid or gaseous form but when used for welding and allied processes, the gases are always used in the gaseous form. Fuel gases, such as acetylene, natural gas, propane etc., and resonator gases, as used in gas lasers, are not covered by this standard. Transportation and handling of gases and containers shall be in accordance with local, national and regional standards and regulations as required.
