This specification presents the minimum process and quality requirements for the torch soldering of ceramics, precious metals, and refractory metals, as well as the alloys of copper (Cu), iron (Fe), nickel (Ni), aluminum (Al), magnesium (Mg), tin (Sn), lead (Pb), and zinc (Zn).

The purpose of this specification is to standardize torch soldering process requirements that will ensure that solder joints attain the quality level required by the application. This document establishes the minimum requirements for processes using a minimum amount of explanatory information so as to limit any ambiguity. This document assigns responsibility for solder joint quality to the Organization Having Quality Responsibility (OHQR) and permits that organization to modify requirements as necessary. However, this specification requires that proper documentation be developed and archived by that organization, to provide the basis and specific details of any such modifications.
