Magnetic Field Immunity testing is essential to verify that electric/electronic products continue to operate as intended when exposed to low-frequency magnetic fields, pulsed magnetic fields and damped oscillatory magnetic fields. This testing assesses a device’s resilience against magnetic disturbances generated by industrial equipment, power distribution systems, rotating machinery, and other sources of high magnetic flux density commonly encountered in real-world environments.
Stancer Testing-Lab is equipped with complete setup for performing compliance magnetic field testing. This includes Helmholtz coils and high-performance magnetic field generators capable of producing uniform and controlled fields across the full range required by the standards. For IEC/EN 61000-4-8, we generate sinusoidal magnetic fields from 50 Hz to 400 Hz, with adjustable field strengths up 1000A/m. This verifies a product’s ability to operate reliably under steady-state magnetic exposure caused by power transformers, motors, distribution systems, and other low-frequency sources.
For IEC/EN 61000-4-9, we generate pulsed magnetic fields representative of high-current switching events, fault conditions, and other transient phenomena typically found in industrial and substation applications. Our system produces controlled current impulses that create repeatable, high-intensity magnetic pulses, allowing precise verification of equipment immunity to sudden electromagnetic disturbances.
By adhering to the full requirements of IEC/EN 61000-4-8 and IEC/EN 61000-4-9, we help manufacturers demonstrate global compliance, validate product robustness, and ensure consistent performance even in environments with substantial magnetic interference.
