Description / Abstract: ISO/TR 19972-1:2009 provides a means for determining the reliability of hydraulic fluid power components using: estimates from a design analysis; analysis of laboratory testing to failure or suspension; analysis of field data; analysis of a substantiation test. These methods apply to the first failures without repairs, but exclude certain infant mortality failures. Specific component test procedures and exclusions are provided in subsequent parts of ISO/TR 19972. ISO/TR 19972-1:2009 also provides calculation methods, reporting descriptions and examples of reliability calculations.
