The withdrawn European emission standard for information technology equipment remains of practical interest in Europe because it governed an enormous installed base of products and because the transition to its successor changed the scope of the requirement as well as its limits. It distinguished class B equipment for the domestic environment from class A equipment for commercial and industrial use, and it covered conducted disturbance at the mains port and radiated disturbance from the enclosure. Its replacement recast the requirement as an emission standard for multimedia equipment, which absorbed the information technology, audio and video and broadcast receiver families into a single document with a broader scope than any of them had alone. A manufacturer holding a report against the withdrawn standard therefore has to establish not only whether the limits have changed but whether the product is now classified differently, since equipment that was class B under the old scheme may fall into a different category under the new one.
