DG-1333, Page 11 Table 2 MIL-STD-461G Test Methods for EMI/RFI Emissions Method Description CE101 Conducted emissions, low-frequency, 30 Hz to 10 kHz CE102 Conducted emissions, high-frequency, 10 kHz to 10 MHz RE101 Radiated emissions, magnetic field, 30 Hz to 100 kHz RE102 Radiated emissions, electric field, 2 MHz to 10 GHz C = conducted, R = radiated, and E = emissions Table 3 IEC 61000-6-4 Test Methods for EMI/RFI Emissions Method Description None Conducted emissions, low-frequency, 30 Hz to 10 kHz CISPR 16 Conducted emissions, high-frequency, 150 kHz to 30 MHz None Radiated emissions, magnetic field, 30 Hz to 100 kHz CISPR 16 Radiated emissions, electric field, 30 MHz to 6 GHz MIL-STD-461G provides the latest revision of domestic guidance for emissions test methods, thus it represents current U.S. practice. IEC 61000-6-4 provides the most recent international guidance for emissions test practices and incorporates by reference the emissions test methods established by the Comité International Spécial des Perturbations Radioélectriques (CISPR) of the IEC. These emissions test methods are defined in parts 2-1 and 2-3 of CISPR 16, “Specification for radio disturbance and immunity measuring apparatus and methods” (Ref. 24 and Ref. 25) while guidance on measurement equipment is given in other specified CISPR16 parts. Because of the non-intrusive nature of emissions measurement, the test methods from either the MIL-STD-461G or IEC 61000-6-4 can be applied in combination based on the emissions phenomenon of interest (e.g., high-frequency or low-frequency, conducted or radiated) without affecting the equipment under test. The individual MIL-STD and IEC emissions test methods are designed to be complementary in frequency range coverage within themselves. If emissions test methods from different standards are used and full coverage of frequency ranges is not provided, then supplemental
