This SAE Aerospace Recommended Practice (ARP) establishes the minumum requirements and procedures for the design, construction, testing and performance of aerospace, maintenance free, factory pre-charged hydraulic accumulators. The accumulators are designed for use in aircraft hydrualic systems at maximum rated operating pressures up to 8000 psi (55158 KPa). The temeprature range of the accumulator is -65 to 275 °F (-54 to 135 °C).

The purpose of this ARP is to define the requirements for maintenance free hydraulic accumulators and provide a specification for use in the procedurement of these devices. Additional or supplemental requirements may be included in the accumulator procurement specification or contract.
