Hydraulic fluid power -- Methods to assess the reliability of hydraulic components -- Part 1: General procedures and calculation method
This standard was last reviewed and confirmed in 2019. Therefore this version remains current.
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.
