This study analyzes the contents of the second revised Regulatory Guide 1.180 (Revision 2) for electromagnetic compatibility qualification published by the U. S. Nuclear Regulatory Commission by comparing them with those of the previous version. The methods and acceptance criteria of both CE101 and CE102 tests pertaining to conductive emission and RE102 test for radiation emission are observed to have been modified in Revision 2. Furthermore, the revised guide is found to afford flexibility in using alternative methods for electromagnetic interference qualification by allowing the combination of different technical base standards.
