Reliability data analysis techniques - Procedures for comparison of two constant failure rates and two constant failure (event) intensities IEC 61650:1997 ED1

Publication date:   Aug 6, 1997

Scope

Specifies procedures to compare two observed - failure rates; - failure intensities; - rates/intensities of relevant events. The procedures are used to determine whether an apparent difference between the two sets of observations can be considered statistically significant. Numerical methods and a graphical procedure are prescribed. Simple practical examples are provided to illustrate how the procedures can be applied.
