Is a standard that specifies the requirements and methods for testing the immunity of electrical and electronic equipment to electrical fast transients (EFT), commonly known as bursts. These bursts are short, rapid, high-frequency pulses that simulates switching transients typically generated by inductive loads, relay contact switching, or other rapid changes in power circuits. The purpose of this standards is to make sure that devices can continue to function properly without data loss or hardware failure when exposed to these types of disturbances.

The testing setup includes a burst generator capable of producing pulses with specified voltage levels, pulse duration, and repetition rates. The pulse are coupled to the EUT through either direct injection into power lines or capacitive coupling to signal and control lines using a Capacitive Coupling Clamp (CCC). This device is used to inject EFT/Burst disturbances into the EUT without a direct electrical connection. The standard burst test set-up includes levels in kV from 0.5kV to several kV and a frequency use of 5kHz or 100kHz, depending on the severity class being tested. The coupling and decoupling network (CDN) is an essential part of the test setup, making sure that the burst energy is properly applied without interfering with unrelated parts of the circuit. The EUT is tested for the response while operational and monitored for any sings of malfunction, disruption, damage. The evaluation criteria include determine whether the equipment experiences a temporary performance drop, loss of data or complete failure (EMC Standards).
