IEC 61124:1997
Reliability testing - Compliance tests for constant failure rate and constant failure intensity
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.

This International Standard gives a number of optimized test plans, the corresponding operating characteristic curves and expected test times. In addition the algorithms for designing test plans using a spreadsheet program are also given, together with guidance on how to choose test plans. This standard does not cover guidance on how to plan, perform, analyse and report a test. This information can be found in IEC 60300-3-5. This standard does not describe test conditions. This information can be found in IEC 60605-2 and in IEC 60605, Parts 3-1 to 3-6.
