Scope

GB/T 36275-2018 is the English-translated version of 专用数字对讲设备电磁兼容限值和测量方法.

GB/T 36275-2018 sets the electromagnetic compatibility limits and measurement methods for private digital mobile radio equipment working between 25 MHz and 1000 MHz.

It covers base stations and repeaters, vehicle and ship mobile stations and handheld stations. The standard classifies the equipment, fixes test conditions, test arrangement, exemption bands and the receiver's narrowband response, and defines performance criteria A, B and C for judging results.

Emission clauses deal with auxiliary equipment enclosure ports, telecom and control ports, DC and AC power ports, harmonic current, flicker and vehicle transients, while immunity clauses cover electrostatic discharge, radiated fields from 80 MHz to 6 GHz, fast transient bursts, surges, conducted RF disturbance, power-frequency magnetic fields and voltage dips. It was issued on 7 June 2018 and has applied since 1 January 2019.
