A procedure specification is a written document providing
direction to the person applying the material joining
process. Details for the preparation and qualification of
procedure specifications for welding (WPS), brazing
(BPS), and fusing (FPS) are given in the respective Parts
addressing those processes. Procedure specifications used
by an organization (see QG-109.2) having responsibility
for operational control of material joining processes shall
have been qualified by that organization, or shall be a standard
procedure specification acceptable under the rules of
the applicable Part for the joining process to be used.
Procedure specifications address the conditions (including
ranges, if any) under which the material joining
process must be performed. These conditions are referred
to in this Section as “variables.” When a procedure specification
is prepared by the organization, it shall address, as
a minimum, the specific essential and nonessential variables
that are applicable to the material joining process
to be used in production. When the referencing Code, standard,
or specification requires toughness qualification
