This Aerospace Recommended Practice (ARP) provides design and test requirements for factory precharged, welded bellows hydraulic accumulators. The requirements contained in this ARP are recommended for inclusion in a Procurement Specification for this type of accumulator. NOTE: Those requirements identified by the use of "shall" are considered to be essential requirements; those requirements identified by the use of "should" are considered to be optional requirements for inclusion in the Specification at the discretion of the Purchaser. In addition, test methods for production acceptance and qualification purposes are also provided to permit a consistent approach for testing to be conducted for the different applications of this type of hydraulic accumulator.
