Scope
This SAE Aerospace Recommended Practice (ARP) is intended as a guide in defining the requirements for aerospace piston separated hydraulic accumulators, including details pertinent to the design, fabrication, and performance of the accumulator. This type of accumulator has a piston separator and contains both high-pressure gas and fluid. The accumulator is used in aerospace hydraulic systems of the following types as defined in AS5440 with design operating pressures of up to 8000 psi (55,160 kPa).
-
Type I: -65 to +160 °F (-54 to +71 °C) fluid temperature
-
Type II: -65 to +275 °F (-54 to +135 °C) fluid temperature
For commercial aerospace or helicopter applications, the information and guidelines of ARP4752 or ARP4925 respectively, are considered.
Rationale
ARP4379 has been revised to issue A for the following reasons:
-
Major editorial changes
-
Document restructured and reformatted in its entirety to reflect latest industry practice and standards
-
Vessel Proof and Burst factors changed for commercial to comply with new regulations
-
Updated references
-
New and revised technical and test requirements have been incorporated

Issuing Committee
A6C4 is responsible for the development of standards, processes, and practices related to Fluid Power Sources (Pumps, Motors, Accumulators), and the integration of these components for Commercial and Military air vehicles. The panel provides a forum for government engineers, prime contractors, and suppliers to exchange technical information, regulatory updates, recent technology developments, issues related to system development and in service operation and lessons learned.
Reference
* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
