This information report presents flexure fatigue strength of tube fitting joints in the form of graphs showing applied deflection D and total calculated axial stress S vs. number of cycles to failure N. The graphs have been prepared from data obtained by actual testing conducted in accordance with ARP 1185.

This recommended practice establishes flexure test procedures to determine and classify the fatigue strengths of reconnectable or permanent hydraulic tube joints. The procedure is intended for conducting flexure tests of fittings and joints for hydraulic tubing materials such as AM 350, 21Cr-6Ni-9Mn steel, or 3Al-2.5V titanium. A mean stress is applied by holding system pressure in the specimens and flexing in a rotary or planar bending test machine.

This Aerospace Recommended Practice establishes flexure test procedures to determine and classify the fatigue strengths of reconnectable or permanent hydraulic tube joints. The procedure is intended for conducting flexure tests of fittings and joints for hydraulic tubing materials such as AM 350, AMS 5561 (21Cr-6Ni-9Mn) steel, or AMS 4944 (3Al-2.5V) titanium.
