7、ponsorship of the Department of the Navy and the Institute of Electrical and Electron-ics Engineers.Prior to 1988, C95 standards were developed by accredited standards committee C95 and submitted to theAmerican National Standards Institute (ANSI) for approval and issuance as ANSI C95 standards. Betw

8、een1988 and 1990, the committee was converted to Standards Coordinating Committee 28 under sponsorship ofthe IEEE Standards Board, and in 2001, became also known as the International Committee on Electromag-netic Safety (ICES). In accordance with policies of the IEEE, C95 standards will be issued an

9、d developed asIEEE standards, as well as being submitted to ANSI for recognition.The present scope of ICES is:“Development of standards for the safe use of electromagnetic energy in the range of 0 Hz300 GHz relativeto the potential hazards due to exposure of such energy to man, volatile materials, a

10、nd explosive devices. Thecommittee will coordinate with other committees whose scopes are contiguous with ICES.”ICES is responsible for this standard. There are ve subcommittees concerned with:I Techniques, Procedures, Instrumentation, and Computation,II Terminology, Units of Measurements, and Hazar

11、d Communication,III Safety Levels with Respect to Human Exposure, 03 kHz,IV Safety Levels with Respect to Human Exposure, 3 kHz300 GHz,V Safety Levels with Respect to Electro-Explosive Devices.Two standards, two guides, and three recommended practices have been issued.

34、omagnetic Fields, 03 kHz1. OverviewThis standard is divided into six clauses. Clause 1 denes the scope and purpose of the standard. Clause 2lists references to other standards that are useful in applying this standard. Clause 3 provides denitions thatare either not found in other standards or have b

35、een modied for use with this standard. Clause 4 denes theprotected population and the mechanisms of interaction. Clause 5 denes the exposure limits. Clause 6details the rationale used in developing this standard.1.1 ScopeThis standard denes exposure levels to protect against adverse effects in human

36、s from exposure to electricand magnetic elds at frequencies from 03 kHz. This standard was developed with respect to establishedmechanisms of biological effects in humans from electric and magnetic eld exposures. It does not apply toexposures encountered during medical procedures. The dened exposure

37、 limits do not necessarily protectagainst interference of medical devices or problems involving metallic implants (see 6.12).Established human mechanisms fall within the category of short-term effects. Such effects are understood interms of recognized interaction mechanisms. Exposure limits dened in

38、 this standard are not based on thepotential effects of long-term exposure because: a) There is not sufcient, reliable evidence to conclude that long-term exposures to electric and mag-netic elds at levels found in communities or occupational environments are adverse to humanhealth or cause a diseas

39、e, including cancer. b) There is no conrmed mechanism that would provide a rm basis to predict adverse effects fromlow-level, long-term exposure.The Subcommittee is aware of reported epidemiological associations between long-term exposure tomagnetic elds and disease, including childhood leukemia in

40、residential environments and chroniclymphocytic leukemia in occupational environments. The interpretation of these associations is unclear,especially since exposure to magnetic elds does not appear to initiate or advance the development ofleukemia or other forms of cancers and other diseases in anim

41、als exposed over much of their lifetime. This isIEEEStd C95.6-2002 IEEE STANDARD FOR SAFETY LEVELS WITH RESPECT TO 2Copyright 2002 IEEE. All rights reserved.consistent with the ndings of interdisciplinary panels of scientists that have evaluated the literature on long-term exposures for scientic and

42、 governmental organizations. The most recent of these major reviewsinclude the Advisory Group on Non-Ionizing Radiation of the UK National Radiological Protection Board(AGNIR B31), the Health Council of the Netherlands (Netherlands B63), the U.S. National Institute ofEnvironmental Health Sciences (N

43、IEHS B64; Olden B68), the Institution of Electrical Engineers (IEEB45), the International Agency for Research on Cancer (IARC B42), the International Commission onNon-Ionizing Radiation Protection (ICNIRP) B43, and the U. S. National Research Council (NRC B65).Because none of the above reviews concl

44、uded that any hazard from long-term exposure has been conrmed,this standard does not propose limits on exposures that are lower than those necessary to protect againstadverse short-term effects. The Subcommittee will continue to evaluate new research and will revise thisstandard should the resolutio

45、n of present uncertainties in the research literature identify a need to limit long-term exposures to values lower than the limits of this standard. The Subcommittee will also continue toevaluate new research on short-term effects and modeling. As stated below, this standard makes reasonableassumpti

46、ons based upon available data. As new data becomes available, the committee will revisit theseassumptions for future revisions.1.2 PurposeThe IEEE has previously dened safety standards for human exposure to electromagnetic elds in thefrequency regime from 3 kHz300 GHz (IEEE B46). The purpose of this

47、 standard is to dene exposurestandards for the frequency regime 03 kHz. For pulsed or nonsinusoidal elds, it may be necessary toevaluate an acceptance criterion at frequencies outside this frequency regime as explained in 5.2.4.2.2.
