This standard applies to electrical control systems of all elevators and escalators. Core revisions include:

first, tightened radiation emission limits, radiation interference limits for elevator control boards, frequency converters, drive systems reduced by 30%, avoiding interference with surrounding medical equipment, communication base stations, smart homes, fire alarm systems, complying with latest requirements of EU EN 55014, US FCC Part 15;

second, strengthened anti-interference ability, elevators must pass four severe tests: electrostatic discharge (±15kV), electrical fast transient burst (±4kV), surge impact (±6kV), radio frequency electromagnetic field (30V/m), ensuring stable operation under extreme electromagnetic environments;

third, power grid fluctuation adaptation, clarifying normal operation of elevators under working conditions of voltage fluctuation ±20%, frequency fluctuation ±5%, voltage dip 70% for 200ms, without tripping, stopping or data loss;

fourth, upgraded electrostatic protection, electrostatic protection level of car control panels, hall call panels and control cabinets ≥±15kV, equipped with anti-static coating, grounding protection, electrostatic discharge devices to prevent electrostatic damage to electronic components;

fifth, unified testing method, formulating globally unified standards for EMC test environment, instruments and equipment, test conditions, judgment criteria, test results mutually recognized globally, simplifying international certification process.


After implementation, China's elevator EMC technology fully aligns with the highest international standards, effectively solving electromagnetic compatibility certification barriers for elevator export to EU, US, Japan and other markets, enhancing China's elevator international market competitiveness.
