Practices peculiar to the drafting of specialized mechanical
assemblies such as those associated with aircraft, auto mobile
bodies, ship frames or certain electrical assemblies are not
considered to be within the scope of this standard. Engineering
design requiring the estimation of strength and performance of
assemblies is not considered to be: within the scope of this
standard.
Purpose. The purpose of this standard is to show
