On October 8, 2025, the International Electrotechnical Commission (IEC) officially issued the revised international standard IEC 61000-6-4:2025 Electromagnetic compatibility (EMC) — Part 6-4: Generic standards — Emission standard for industrial environments, adding a special technical specification for electromagnetic compatibility of elevators and escalators, which is the core unified guideline in the field of elevator electromagnetic compatibility worldwide. The core contents of this standard revision include: First, clarify the general requirements for electromagnetic compatibility of elevators and escalators, covering the electromagnetic emission and immunity requirements of elevator control systems, drive systems, safety systems and monitoring systems. Second, refine the limit standards for elevator electromagnetic emission, and formulate differentiated electromagnetic emission limits for different use scenarios such as industrial environment, residential environment and commercial environment, to ensure that elevator operation does not interfere with surrounding electronic equipment. Third, standardize the immunity test requirements for elevators, clarify the process, methods and qualification criteria for immunity tests such as electrostatic discharge, radio frequency electromagnetic field, electrical fast transient burst, surge, and voltage dip. Fourth, add special requirements for electromagnetic compatibility of smart elevators, and formulate special test and design standards for the electromagnetic compatibility performance of IoT elevators, remote monitoring systems, and wireless communication modules. Fifth, clarify the electromagnetic compatibility design specifications for elevators, and formulate standardized guidelines for grounding design, shielding design, filtering design, and wiring design of elevator electrical systems, to improve the electromagnetic compatibility performance of elevators from the design source. Sixth, standardize the on-site test requirements for elevator electromagnetic compatibility, and formulate the on-site electromagnetic compatibility test process and method after the elevator installation is completed, to ensure that the electromagnetic compatibility performance of the elevator in the actual use scenario meets the standard. After its release, the standard has been adopted as a national standard by many countries and regions around the world such as the European Union, China, the United States and Japan, comprehensively improving the electrical safety and electromagnetic compatibility performance of global elevators.
