Description / Abstract:
This SAE Aerospace Recommended Practice (ARP) is intended to
interpret and clarify engineering drawing requirements relating to
the manufacture and inspection of fluid system couplings, tube
fittings, and hose ends. Because it is impractical to define every
minute detail of the part on the face of the drawing, this document
describes interpretations of dimensioning of general machining
features and otherwise undefined tolerances that fall under the
heading of "good shop practice". This document serves as a
supplement to engineering drawings when referenced on applicable
documents.
