EMC Directive

The Council Directive 89/336/EEC of 3 May 1989 on the approximation of the laws of the Member States relating to electromagnetic compatibility (EMC Directive) governs on the one hand the electromagnetic emissions of this equipment in order to ensure that, in its intended use, such equipment does not disturb radio and telecommunication as well as other equipment. In the other the Directive also governs the immunity of such equipment to interference and seeks to ensure that this equipment is not disturbed by radio emissions normally present used as intended.

There are currently three conformity assessment procedures for such equipment:

• The first is self-declaration by the manufacturer where he/she applies the relevant European harmonised standards.
• The second, where such standards are not available, partially applied, or do not cover all of the requirements, involves the completion of a Technical Construction File (TCF), with a report or certificate from a Competent Body.
• The third procedure, which applies to radio-communication equipment and involves Notified Bodies, is now no longer relevant for almost all such equipment, given the advent of the R&TTE Directive 1999/5/EC.

FCC Policy on Human Exposure to Radiofrequency Electromagnetic Fields

The FCC is required by the National Environmental Policy Act of 1969 to evaluate the effect of emissions from FCC-regulated transmitters on the quality of the human environment. At the present time there is no federally-mandated radio frequency (RF) exposure standard. However, several non-government organizations, such as the American National Standards Institute (ANSI), the Institute of Electrical and Electronics Engineers, Inc. (IEEE), and the National Council on Radiation Protection and Measurements (NCRP) have issued recommendations for human exposure to RF electromagnetic fields. The potential hazards associated with RF electromagnetic fields are discussed in OET Bulletin No. 56, "Questions and Answers About the Biological Effects and Potential Hazards of Radiofrequency Electromagnetic Fields."
