EN 50081-1
EN 50081-1 Electromagnetic Compatibility - Generic Emission Standard Part 1: Residential, Commercial and Light Industry - Withdrawn EN 50081-1 (1992) requires that equipment intended for use in the residential, commercial, and light industrial environments complies with the Class B limit of EN 55022, while EN 50081-2 (1993) allows equipment for use in the heavy industrial environment to comply with Class A limit. EN 55022 does not rigidly relate the A and B classification to particular environments but states that Class B ITE is intended primarily for use in the domestic environment.
