PD ISO/TR 19972-1:2009 PDF

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.
