Electromagnetic Disturbances Resistibility
These tests require the equipment to be powered and have a number of disturbances applied for five to ten minutes, with a minimum interval of one minute in between, following which the products must remain in working condition. Some of these include:
1500V voltage peak applied to telecommunication port, or 1000V peak in case it is an internal port
4000V voltage peak applied between the power outlet and the ground
2000V voltage peak applied to the power outlet
