This recommended practice describes methods for measuring and computing external electric, magnetic, and electromagnetic fields to which persons could be exposed over the frequency range of 0 Hz to 300 GHz. Instrument characteristics and the methods of calibrating such instruments, and methods for computation and measurement of the resulting fields and currents that are induced in bodies of humans exposed to these fields, are included. The purpose of this recommended practice is to specify techniques and instrumentation for the measurement and computation of potentially hazardous electric, magnetic, and electromagnetic fields both in the near-field and the far-field of the source. In so doing, this document incorporates and extends the specifications previously set forth in IEEE Std C95.3™-2002 [B192] and IEEE Std C95.3.1™-2010 [B193]. In addition to measurement and computation of exposure fields, this document includes a description of the concepts, techniques, and instruments that can be applied to the measurement and computation of the specific absorption rate or the electric field strength in organisms (including humans) and phantoms exposed to electromagnetic fields. Guidance on measurement and computation of induced current and contact current is also included. This document is intended primarily for use by engineers, biophysicists, and other specialists who are familiar with basic electromagnetic field theory and practice, and the potential hazards associated with exposure to such fields Revision Standard - Active. Best practices are described for the development, validation, and application of methods for the computation and measurement of relevant metrics characterizing human exposure to electric and/or magnetic fields (collectively, electromagnetic fields) over the frequency range of 0 Hz to 300 GHz. This recommended practice is a replacement for IEEE Std C95.3-2002 and IEEE Std C95.3.1-2010, extensively revising the contents from those and harmonizing with IEEE Std C95.1-2019. Detailed methodology is not described; rather, requirements for best practice are expressed through guidance and references to other documents and standards. Examples are included to clarify the guidance. This recommended practice is intended for professional users who are familiar with basic electromagnetic field theory and practice and for persons involved in specifying or implementing critical hazard assessments or surveys such as those described in IEEE Std C95.7-2014.
