Introduction This introduction is not part of IEEE Std C95.1a-2010, IEEE Standard for Safety Levels with Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHzAmendment 1: Specifies Ceiling Limits for Induced and Contact Current, Clarifies Distincti

11、ons between Localized Exposure and Spatial Peak Power Density. IEEE Std C95.1-2005 was approved by the IEEE-SA Standards Board on 3 October 2005. During final pre-publication review, questions were raised by the TC95/SC4 Editorial Working Group regarding possible confusion by readers, concerning use

12、 of the terms localized exposure and spatial peak power density, which could not be clarified by simple editorial changes. Moreover, after publication it was discovered that ceiling values for induced and contact currents that appeared in the 1999 edition of IEEE Std C95.1 were inadvertently not inc

13、luded in IEEE Std C95.1-2005. This amendment clarifies the distinctions between localized exposure and spatial peak power density, specifies ceiling values for induced and contact currents, and clarifies other technical issues identified subsequent to publication of IEEE Std C95.1-2005.

NOTEThe editing instructions contained in this amendment define how to merge the material cont

41、ained herein into the existing base standard and its amendments to form the comprehensive standard.1The editing instructions are shown in bold italic. Four editing instructions are used: change, delete, insert, and replace. Change is used to make corrections in existing text or tables. The editing i

42、nstruction specifies the location of the change and describes what is being changed by using strikethrough (to remove old material) and underscore (to add new material). Delete removes existing material. Insert adds new material without disturbing the existing material. Insertions may require renumb

43、ering. If so, renumbering instructions are given in the editing instructions. Replace is used to make changes in figures or equations by removing the existing figure or equation and replacing it with a new one. Editing instructions, change markings, and this NOTE will not be carried over into future

44、 editions because the changes will be incorporated into the base standard. 1Notes in text, tables, and figures are given for information only and do not contain requirements needed to implement the standard. 1 Copyright 2010 IEEE.

46、tions, acronyms, abbreviations, and letter symbols 3.1 Definitions Replace 3.1.33 with the following: 3.1.33 localized exposure: Exposure of only a portion of the body. See also: RF hot spot. Replace 3.1.58 with the following: 3.1.58 RF hot spot: A highly localized area of relatively more intense RF

47、 energy that manifests itself in two principal ways: 1) Near an unpowered conductive object that becomes a source of intense electric or magnetic fields (often referred to as re-radiation) and is surrounded by ambient fields of lower field strength, 2) From reflections and/or narrow beams produced b

48、y high-gain radiating antennas or other highly directional sources. In both cases, there are usually rapid changes in field strength over distances that are small with respect to the exposed object (the body or body part) and wavelength. RF hot spots are normally associated with non-uniform exposure

49、 of the body (localized exposure). Such non-uniformity does not necessarily cause, and is not to be confused with, an actual thermal hot spot within the absorbing body. 4.
