GB/T 17626.39-2023 Active

This document specifies the immunity requirements for electrical and electronic equipment exposed to radiated electromagnetic energy from radio frequency (RF) transmitters used at close range. It establishes test levels and the required test procedures. The applicable frequency range is 9 kHz to 6 GHz. It considers fixed installation equipment exposed to portable transmitter devices, mobile equipment exposed to fixed transmitter devices, and mobile equipment exposed to other mobile transmitter devices.
This document aims to establish a common benchmark for evaluating the immunity requirements of electrical and electronic equipment exposed to RF electromagnetic fields from close-range radiation sources. This document does not replace the general immunity requirements for electrical and electronic equipment to radiated electromagnetic energy specified in IEC 61000-4-3 and other parts of IEC 61000, and is only applicable to equipment or systems exposed to close-range interference sources.
In this document, "close range" generally refers to the distance between the transmission source and the affected equipment, which should not exceed 200 mm for frequencies above 26 MHz and 500 mm for frequencies below 26 MHz.
The test methods in this document describe a consistent approach to evaluating the immunity of equipment or systems to specific phenomena within their respective frequency ranges. The product committee will consider the applicability of the tests and, if necessary, select the appropriate test methods based on the equipment under test (EUT), frequency range, and interference sources, etc.
Note: According to the description in IEC GUIDE 107, this document is a basic electromagnetic compatibility (EMC) standard for use by product committees. As stated in IEC GUIDE 107, product committees are responsible for determining whether to adopt this document, and if they do, they are responsible for determining appropriate test levels and performance
