The Reliability started for MILitary purposes during World War II in 1942 getting more important for maintenance safety etc in modern society. As technologies develop also international standards for measuring the reliability is advancing.
RAMS activities for maintenance safety verification is material to national railroad. And for this it needs quick response for the changes of standards. Even now standards are upgrading for developing electronic technologies. Therefore analysis of failure rate's trend about such standards is judged necessary. So We submit a this paper for comparative analysis of changing process standards according to development of electronic technologies and reliability.
At first we compared actual usage ratio of standards for understanding the current state of usage. Based of these state of usage discuss the major standard. And then introduced reliability standards's trend calculation method of failure rate and difference of failure rate calculation standard according to march of time.
In this paper used standards are MIL-HDBK-217F Telcodia etc.
