Abstract:By comparing the new edtion with the previous edition,a brief introduction on
the change of the General EMC Emission Standard GB17799.3 was given. In this
article, the application range of general EMC standard was elaborated,the application
method of uncertainty was explained, the new increased alternate testing method of
enclosure, as well as the requirements of high power equipment with low voltage ac
power supply port 、 dc port and telecom/network port was deeply analyzed .
Keywords: uncertainty; FAR; TEM cell; DC power port; telecommunications/network
port;general standard
