These formulae shall be used to determine drop dimensions for simple bend tube fittings utilizing flare and flareless end connection designs from 0° to 90° used in aircraft and aerospace applications. Individual design standards shall specify parameters, such as centerline bend radius (R), straight tangent length to accommodate bending equipment (X1 and X2), and nut to be used.
This Aerospace Recommended Practice (ARP) establishes uniform requirements and procedures to determine the torsional strength of permanent hydraulic tube joints. It also establishes testing equipment and apparatus for torsion testing.
This SAE Aerospace Standard establishes the requirements and procedures for Contractile Strain Ratio (CSR) testing of cold-worked and stress-relieved titanium tubing such as Ti-3AI-2.5V tubing per AMS 4944.
This document describes a method for determining the specific gravity of tubing, fabricated from polytetrafluoroethylene, after a controlled heating and cooling cycle. The specific gravity obtained by this method is a measure of relative molecular weight of the resin. The measure, termed relative specific gravity (RSG), increases with decreasing molecular weight (see 2.3).
This SAE Aerospace Recommended Practice (ARP) lists wrenching surface sizes and tolerances for fluid fittings which utilize machined or unmachined hex bar dimensions and machined or forged wrenching surfaces across the center body section of shape fittings.
