scope:

This document specifies the compositions of a range of filler metals used for brazing. The filler metals have been divided into seven classes, related to their composition but not necessarily to the major element present, see annex A. In the case of composite products such as flux-coated rods, pastes or plastics tapes, the standard only covers the filler metal that forms part of such products. Although the melting range is given in the tables, it will necessarily vary within the compositional range of the filler metal and can only be regarded as approximate. Therefore, it is not a part of the specification and is given only for information. Technical delivery conditions are given for brazing filler metals and products containing brazing filler metals with other constituents such as flux and/or binders.
NOTE For some applications, e.g. precious metal jewelry, aerospace and dental, filler metals other than those included in this standard will often be used and these are covered by other standards to which reference should be made.
