This specification prescribes requirements for the classification of filler metals for brazing and braze welding. It includes brazing filler metals for brazing with or without a flux and in all protective atmospheres for various applications, including those for vacuum service.1 In the case of composite products – flux cored wire or rods, flux-coated rods, transfer tape, or paste – this standard covers only the filler metal that forms part of such products.
1 Filler metals for vacuum service are for devices operating in vacuum service, regardless of the atmosphere used in making the joint.
