IEC 61124 Ed. 1.0 b:1997

Specifies procedures to test whether an observed value of: - failure rate; - failure intensity; - mean time to failure; - mean operating time between failures; complies with a given requirement. Three types of test plans are prescribed as follows: - sequential test plans; - time/failure terminated test plan; - fixed calendar time/failure terminated test plans. Cancels and replaces IEC 60605-7, published in 1978, and its amendment 1 (1990), of which its constitutes a technical revision.
