1 Scope

GB/T 17626 in this section to consider immunity tests electrical and/or electronic devices in Reverberation chamber, intentionally or unintentionally radiated emission Test and shielding effectiveness testing. This section established test procedures required for the implementation of these tests. This section considers only the radiation phenomena.

The purpose of this section is to establish a use Reverberation chambers assessment of electrical and/or electronic equipment to determine the electrical performance and RF electromagnetic field Generic specification level radiation emitting electronic device.

Note. This section sets out the impact of electromagnetic radiation on equipment and test methods for the electromagnetic radiation emitted by the device concerned. The simulation and measurement of electromagnetic radiation is insufficient to Volume to determine the impact of electromagnetic radiation on the device. The main purpose is to make the specified test methods test results with sufficient reproducibility and repeatability and Electromagnetic effect qualitative analysis.

The purpose of this section is not required test method for a specific device or system suitable for, but to provide for all related products through committee with reference base. Products Committee should consult the National Standardization Technical Committee on Radio Interference or the National Standardization Technical Committee Electromagnetic Compatibility I would choose radiation emission limits and test methods. By the product committee responsible for selecting the appropriate test methods and equipment within the scope of its anti jurisdiction it limits the degree of interference can also be used, such as IEC 61000-4-3, CISPR16-2-3 CISPR16-2-4 and other standards such as 1).

1) the need for further information to the National Standardization Technical Committee on Radio Interference or national EMC Standardization Technical Committee advice.
