GB/T 17626.31-2021Electromagnetic compatibility - Testing and measurement techniques - Part 31: AC mains ports broadband conducted disturbance immunity test (English PDF)

1 Scope

This document is about electrical and electronic equipment's effects on the production of intentional and/or unintentional broadband signal sources in the frequency range of 150kHz to 80MHz:

Conducted immunity requirements for generated electromagnetic disturbances:

The purpose of this document is to establish a general benchmark for assessing electrical and electronic equipment's AC power port exposure to intentional and/or unintentional

Immunity to conducted disturbances from broadband signal sources: The test methods specified in this document describe the evaluation of a device or system for a defined phenomenon

Conformance method of noise immunity:

Devices that do not have at least one AC power port are not required: Not intended to be connected to the power terminals on the AC power distribution network

The port is not considered an "AC power port" and is therefore not a requirement:

This document only applies to single-phase equipment with rated input current <= 16A; multi-phase equipment and/or single-phase equipment with rated input current greater than 16A

Applicable methods for broadband harassment of equipment are still under consideration:

Note: This document is the basic EMC publication used by product committees as described in IEC GUIDE 107: As stated in IEC GUIDE107, the product

The committee is responsible for determining whether to apply this immunity standard, and if so, they are responsible for determining the appropriate test levels and performance criteria: IEC /TC77 and its sub-committees are willing to cooperate with product committees to evaluate specific immunity test levels of their products:
