Accredited Standards Committee C63® - EMC

SC2 ScopeScope Unchanged E3 Terminology Definitions

Subcommittee 2 is responsible for developing, updating, and/or modifying definitions and terminology related to electromagnetic compatibility (EMC) including electromagnetic environmental effects (E3).  The subcommittee will also recommend and/or consider definitions for ratification and harmonization with the U.S. military and international standardization bodies as needed. The subcommittee will maintain ANSI C63.14, “American National Standard, Dictionary of Electromagnetic Compatibility (EMC) including Electromagnetic Environmental Effects (E3).”
