BS EN ISO 14175:2008

Welding consumables. Gases and gas mixtures for fusion welding and allied processes

Status : Current, Confirmed   Published : March 2008



BS EN ISO 14175 specifies requirements for the classification of gases and gas mixtures used in fusion welding and allied processes including, but not limited to:

  • tungsten arc welding 
  • gas-shielded metal arc welding 
  • plasma arc welding
  • plasma arc cutting 
  • laser welding 
  • laser cutting
  • arc braze welding.

The purpose of BS EN ISO 14175 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 qualification 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.

BS EN ISO 14175 supersedes BS EN 439:1994 which is withdrawn.
