Application Summary AI generated

This standard specifies the performance requirements, testing methods, and selection criteria for protective devices designed to mitigate conducted disturbances caused by High-Altitude Electromagnetic Pulse (HEMP) in electrical and electronic systems. It is applied in the design and installation of critical infrastructure, such as telecommunications, power grids, and military facilities, where protection against HEMP-induced surges is necessary to ensure equipment survivability and operational continuity. The standard provides guidelines for engineers and procurement professionals to specify, test, and verify protective devices like filters and surge arrestors in compliance with electromagnetic compatibility (EMC) requirements.
