ARP4296 DRAWING INTERPRETATIONS, STANDARD MACHINING PRACTICE, TUBE FITTINGS AND CONNECTORS, FLUID SYSTEMS

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