CURRENT
MAP2261
This SAE Metric Aerospace Recommended Practice (MAP) establishes the requirements for preparing a specification for fluid couplings for spacecraft servicing. The objective of this document is to provide design, development, verification, storage, and delivery requirement guidelines for the preparation of specifications for fluid couplings and the ancillary hardware for use with serviceable spacecraft designed for use in the space environment. The couplings shall be capable of resupplying storable propellants, cryogenic liquids, and gases to a variety of spacecrafts.

Qualification of Hydraulic Tube Joints to Specified Flexure Fatigue Requirements
2019-01-03
WIP
ARP1258C
This SAE Aerospace Recommended Practice (ARP) establishes the method for qualification testing of tube joints and fitting attachments, using the flexure test method described in ARP1185. This qualification test method allows the determination of S-N type stress versus cycles or D-N type deflection versus cycles curves, as illustrated in AIR1418 as an alternate to flexure testing to a minimum endurance stress level.

FLEXURE TESTING OF HYDRAULIC TUBING JOINTS AND FITTINGS
1973-12-01
HISTORICAL
ARP1185
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.
