GB/T 17626.3-2016

This part of GB/T 17626 applies to the electromagnetic field radiation immunity requirements of electrical and electronic equipment, and specifies the test levels and necessary test procedures.
The purpose of this part is to establish the basis for evaluating the immunity of electrical and electronic equipment to radiofrequency electromagnetic field radiation. The test methods described in this part describe the compliance methods for evaluating the resistance of equipment or systems to certain environmental conditions.
Note 1: As described in GB/Z 18509, this part is a basic EMC publication for use by relevant professional standardization technical committees. At the same time, GB/Z 18509 stipulates that relevant professional standardization technical committees are responsible for determining whether this immunity test standard is applicable. If applicable, they are responsible for determining the appropriate test levels and performance criteria. The National Electromagnetic Compatibility Standardization Technical Committee (SAC/TC 246) and its branches cooperate with relevant professional standardization technical committees to evaluate the test levels and performance criteria for specific immunity tests on their products.
This part applies to immunity tests against radiofrequency electromagnetic fields from all emission sources.
Particular attention is paid to preventing radiofrequency radiation from digital wireless telephones and other radiofrequency emission devices.
Note 2: This part specifies test methods for evaluating the degree of impact on EUTs under electromagnetic radiation conditions. The simulation and measurement of electromagnetic radiation are not accurate enough to quantitatively determine this degree of impact. The purpose of the defined test methods is to establish a method for qualitative analysis that can obtain good reproducible measurement results for various EUTs.
This part is an independent test meth
