The conducted immunity (CI) and radiated immunity (RI) test methods in this recommended practice do not universally apply to every product. Applicable test methods should be selected. A qualified EMC engineer should document test planning and the rationale for using particular immunity tests. This document is intended to Identify preferred or optional immunity test methods.Describe specific measurement techniques.Suggest product performance degradation criteria as applicable to general and specific products.Identify test instrumentation specifications. Wherever possible, existing voluntary standards are utilized and summarized. It should be noted that the techniques listed herein should in no way limit the user to a particular method to increase product immunity. The immunity levels in this document are recommended. Should product classifications and type have other immunity levels that apply, they shall take precedence. Equipment developed for military applications should use MIL-STD-461E or later editions for test procedures and limits.
