Short Guide to EFT Testing: Testing for Safe Medical Devices
Electrical Fat Transient or EFT Testing refers to a conducted immunity test designed to evaluate the resilience of electrical and electronic components against high-frequency transients. This Testingis used to stimulate the disturbance which is caused by switching operations and power line transients. • Purpose: This has the aim of ensuring that the device can withstand sudden voltage changes without sustaining damage. • Standard: Conducted in accordance with IEC/EN 61000-4-4, defining levels and procedures. • Levels: Tests involve and executes by applying voltage peaks from 0.5 kV to over 4 kV, based on the severity of the environment. Benefits • Ensures Product Reliability: It verifies that electronic systems remain stable. • Ensures Compliance: It helps meet international regulatory standards, which are crucial for product certification and safety. • Identifies Design Weaknesses: It reveals flaws in PCB layouts and firmware handling early, preventing expensive redesigns. • Increase...
