scope:

This Publication provides recommendations for the collection of reliability data relating to the field performance of electronic items. It provides for the acquisition of data sufficiently comprehensive to permit detailed failure and failure-rate analysis of items operating under various conditions: time, environment, storage, stand-by, repair, etc. It emphasizes that meaningful reliability data must include the data on successes (performance without failure),as well as data on failures. In other words, this Publication is not intended to be only a failure-reporting Recommendation. This Publication also provides for data from which the maintenance and availabil ity aspects of items may be considered.
