  • This recommended practice provides guidelines for assessing the reliability of hydraulic components by testing and reporting for components used in fluid power systems. Specific requirements for assessing the reliability of the components listed in 1.2 are contained in annexes to this practice.

    This practice applies to the following components:

    a) accumulators;

    b) hydraulic cylinders;

    c) hydraulic filters;

    d) hydraulic pumps and motors;

    e) hydraulic valves;

    This practice provides:

    a) general requirements for reliability testing;

    b) statistical methods for determining reliability;

    c) an example of reliability calculations;

    d) annexes with specific test guidelines and threshold level criteria for each component listed in 1.2.
