26、, IEEE Recommended Practice for Determining Safe DistancesFrom Radio Frequency Transmitting Antennas When Using Electric Blasting Caps During Explosive Operations.)In 1960, the American Standards Association approved the initiation of the Radiation Hazards Standardsproject under the co-sponsorship o
27、f the Department of the Navy and the Institute of Electrical andElectronics Engineers.In 1965 and 1966, the Institute of Makers of Explosives (IME), a trade group with headquarters inWashington, DC, sponsored research on RF hazards to electric blasting caps. Laboratory tests and analyseswere perform
28、ed at the Franklin Institute, Philadelphia, Pennsylvania. Tables of safe distances were includedin this early work. Since 1966, the IME has published updated tables of safe distances from time to time.Standards committees have included technical people from the IME and from the Franklin Institute.Pr
29、ior to 1988, C95 standards were developed by an accredited standards committee C95, and submitted toANSI for approval and issuance as ANSI C95 standards. Between 1988 and 1990, the committee wasconverted to Standards Coordinating Committee 28 (SCC 28) under the sponsorship of the IEEE StandardsBoard
30、. In 2001, the IEEE SA-Standards Board approved the title International Committee onElectromagnetic Safety (ICES) for the SCC 28. In accordance with policies of the IEEE, C95 standardswill be issued and developed as IEEE standards, and will be submitted to ANSI for recognition.The present scope of I
31、EEE SCC 28 is Development of standards for the safe use of electromagnetic energyin the range of 0 Hz to 300 GHz relative to the potential hazards of exposure of man, volatile materials, andexplosive devices to such energy. It is not intended to include infrared, visible, ultraviolet, or ionizingrad
32、iation. The committee will coordinate with other committees whose scopes are contiguous with ICESSCC 28.The IEEE International Committee on Electromagnetic Safety is responsible for this recommended practice.There are five subcommittees concerned witha) Techniques, Procedures, Instrumentation, and C
33、omputationb) Terminology, Units of Measurements and Hazard Communicationc) Safety Levels with Respect to Human Exposure, 03 kHzd) Safety Levels with Respect to Human Exposure, 3 kHz300 GHze) Safety Levels with Respect to Elector-Explosive DevicesTwo standards, two guides, and two recommended practic
34、es have been issued. Current versions are asfollows:IEEE Std C95.1TM, 1999 Edition, IEEE Standard for Safety Levels with Respect to Human Exposure toRadio Frequency Electromagnetic Fields, 3 kHz to 300 GHz.bIEEE C95.2TM-1999, IEEE Standard for Radio Frequency Energy and Current Flow Symbols. bInform
