This International Standard should be used as a reference in the drafting of application codes and/or
other application standards. It may be used within a total quality system for the production of
satisfactory welded joints. It provides three sets of dimensional values from which a selection can be
made for a particular application. The quality level necessary in each case should be defined by the
application standard or the responsible designer in conjunction with the manufacturer, user and/or
other parties concerned. The level shall be prescribed before the start of production, preferably
at the inquiry or order stage. For special purposes, additional details may need to be prescribed.
The quality levels given in this International Standard are intended to provide basic reference
data and are not specifically related to any particular application. They refer to the types of
welded joints in a fabrication and not to the complete product or component itself. It is possible,
therefore, for different quality levels to be applied to individual welded joints in the same product or
component.
