ISO/TR 19972-1:2009

Hydraulic fluid power — Methods to assess the reliability of hydraulic components — Part 1: General procedures and calculation method

Scope

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.
