Abstract: The primary tasks of EMP (Electromagnetic Pulse) hardening asse ssment of complex
systems are introduced, and the statistical descriptive method of EMP resistant performance of the systems
is described in detail. According to the different levels (or purposes) of the assessment, four types of EMP
testing are defined as well. Besides, the various sources of random errors in EMP hardening margin
evaluation, and the method to estimate the standard deviation of the total error are also analyzed. To
estimate the lower-bound of the margin and its Reliability-Confidence,an algorithm is developed and the
preconditions for its application are also analyzed. As an application guide for the algorithm, the
evaluation on EMP hardening mar
