Unification of Electromagnetic Specifications and Standards, Part I-Evaluation of Existing Practices

摘要

To establish a basis for evaluating standards, specifications, and codes by which electronic equipment and systems are procured and installed, a review of electromagnetic interference control has been made. It is concluded that effective interference control is achieved by establishing an impervious barrier between the offending source and the circuit to be protected. This concept is developed and applied to practical control requirements for equipment and facilities. Over 70 standards, specifications, and codes have been reviewed to assess where they are incompatible with these principles. It is postulated that a set of documents compatible with each other and with requirements for electromagnetic pulse (EMP) hardening, interference control, and communications security can be developed. This report documents Phase I of this project which was limited to the development of a general interference control model and its application to the review of existing standards and practices. In Phase II alternatives to the incompatible requirements found during the review will be developed and demonstrated.
