Prior to 1988, C95 standards were developed by Accredited Standards Committee C95,and submitted to the American National Standards Institute (ANSI) for approval and issuance as ANSI C95standards. Between 1988 and 1990, the committee was converted to Standards Coordinating Commit

In 2001, the IEEE Standards AssociationStandards Board approved the name “International Committee on Electromagnetic Safety (ICES)” for SCC28 to better reflect the scope of the committee and its international membership. In accordance

11、 with policiesof the IEEE, C95 standards are issued and developed as IEEE standards, as well as submitted to ANSI forrecognition.In 2005, SCC 28 and SCC 34 became Technical Committees 95 and 34, respectively, under a new commit-tee, SCC 39, which is now called ICES.The present scope of IEEE ICES is

44、to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz1. Overview1.1 ScopeRecommendations are made to protect against established adverse health effects in human beings associatedwith exposure to electric, magnetic and electromagnetic fields in the frequency range of 3 kHz to

45、300 GHz.The recommendations are expressed in terms of basic restrictions (BRs) and maximum permissible exposure(MPE) values. The BRs are limits on internal fields, specific absorption rate (SAR), and current density; theMPEs, which are derived from the BRs, are limits on external fields and induced

46、and contact current. Therecommendations, which protect against effects associated with electrostimulation and tissue and whole-body heating, are intended to apply to all human exposures except for exposure of patients by, or under thedirection of, physicians and medical professionals. These recommen

47、dations are not intended for the purposeof preventing interference with medical and other devices that may exhibit susceptibility to radio frequency(RF) fields. The recommendations at 300 GHz are compatible with existing recommendations for safe expo-sure in the infrared frequency range, which begin

48、s at 300 GHz, cf., ANSI Z136.1-2000 B71, ICNIRPguidelines B63, and IEC 60825-1 B65. IEEE Std C95.6-20022is the applicable standard for use at fre-quencies below 3 kHz. 1.2 PurposeThe purpose of this standard is to provide exposure limits to protect against established adverse effects tohuman health

49、induced by exposure to RF electric, magnetic and electromagnetic fields over the frequencyrange of 3 kHz to 300 GHz.1The numbers in brackets correspond to those of the bibliography in Annex G.2Information on references can be found in Clause 2.IEEEStd C95.1-2005 IEEE STANDARD FOR SAFETY LEVELS WITH RESPECT TO HUMAN EXPOSURE2 Copyright 2006 IEEE.
