This SAE Aerospace Standard (AS) establishes the requirements for 24 degree cone AS5827 or EN 6123 flareless Ring locked fitting assemblies per AS5550 and AS5865, for use in aircraft fluid systems at nominal operating pressure of 5080 psi (35 000 kPa) maximum and operating temperature range of -65 to +275 °F (-54 to +135 °C). The general requirements shall be for, but not limited to, commercial aircraft hydraulic components per AS4941, using port configuration as specified in AS5551.

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. A mean stress is applied by holding system pressure in the specimens and flexing in a rotary or planar bending test machine. Flexure testing of metric tubing joints and fittings is covered by MA 2003.

This SAE Aerospace Information Report (AIR) establishes the specifications and descriptions of the critical components and operational guidelines for the standard hydraulic impulse machine for testing hydraulic hose assemblies, tubing, coils, fittings and similar fluid system components. This revision to the AIR1228 provides a description of a system that meets the requirements for specifications including: AS603, AS4265, and ARP1383. This impulse system utilizes closed loop servo control with specifically generated command signal waveforms. Data accuracy and integrity are emphasized in this revision. Knowing the uncertainty of the pressure measurement is important whether using a resonator tube system, as described in the original release of this document, or a closed-loop systems as described in this release. The accuracy of the data measurement system and consistency of the pressure waveform are fundamental to test validity, regardless of the system type.
