Several American industries are combining forces for a further assault on plans by the European Community to impose additional limits on harmonic emissions fed back into power lines. Earlier, U.S. delegations succeeded in obtaining a four-year moratorium on the limits, as well as an interim acceptance of a proposed U.S. revision to them. The Americans are using the interlude to gather more facts to support their claim that the proposed limits are overly stringent and will shut European markets for a vast range of electrical, electronic, and telecommunications products that meet U.S. and Canadian standards. The limits are part of the Electromagnetic Compatibility Standard of the International Electrotechnical Commission based in Geneva. The Electronics Industries Association (EIA), based in Washington, has formed a coalition of several large American trade associations.
