MIL-STD-1542B, MILITARY STANDARD: ELECTROMAGNETIC COMPATIBILITY AND GROUNDING REQUIREMENTS FOR SPACE SYSTEM FACILITIES (15 NOV 1991)., The purpose of this standard is to specify the design, performance, and verification requirements for electrical subsystems for space system facilities, including electromagnetic compatibility (EMC), electrical power grounding, bonding, shielding, lightning protection, and TEMPEST security. These requirements are interrelated and interdependent, and therefore require an integrated approach in the design.
