Introduction

Electromagnetic compatibility (EMC) risk assessment technology is based on the EMC design method and uses common risk assessment methods:

The process of risk assessment divides risk levels, establishes an ideal model for equipment design, and determines risk factors to identify EMC risks:

GB/T 43460 "Electromagnetic Compatibility Risk Analysis Method" aims to establish the analysis of risk elements suitable for the ideal model of EMC risk assessment:

The method is intended to consist of the following parts:

— Part 1: Cable shielding: The purpose is to give the operation method of cable shielding risk elements in the ideal model of EMC risk assessment: Laws and procedures:

— Part 2: Port EMC device: The purpose is to give the risk requirements of the port EMC device in the ideal model of EMC risk assessment:

Element operating methods and procedures:

— Part 3: Grounding: The purpose is to provide the operating methods and procedures for the grounding risk elements in the ideal model of EMC risk assessment:

— Part 4: Signal processing: The purpose is to provide an operational method for signal processing risk elements in an ideal model for EMC risk assessment: Laws and procedures:

— Part 5: Crosstalk processing: The purpose is to provide an operation method for crosstalk processing risk elements in the ideal model of EMC risk assessment: Laws and procedures:
