1 Scope Thispart of ISO/TR 19972 provides a means for determining the reliability of hydraulic fluid power components using:
a) estimates from a design analysis;
b) analysis of laboratory testing to failure or suspension;
c) analysis of field data;
d) 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 will be provided in subsequent parts of ISO/TR 19972. This part of ISO/TR 19972 also provides calculation methods, reporting descriptions and examples of reliability calculations.
