A listing of possible measurement goals related to characterizing quasi-static magnetic and electric fields and possible methods for their accomplishment is provided.

Techniques and instrumentation for the measurement and computation of potentially hazardous electromagnetic (EM) fields both in the near field and the far field of the electromagnetic source are specified. The specifications previously set forth in IEEE Std C95.3-1991 are extended and combined. Leakage and near-field measurements and a description of the concepts, techniques, and instruments that can be applied to the measurement of specific absorption rate (SAR) or the electric field strength in organisms (including humans) and phantoms exposed to electromagnetic fields are included. Below 100 MHz, the current flowing through the body to ground is measurable and can be used to determine the SAR and, therefore, a brief treatment of low-frequency body current measurement is included. The "IEEE Get Program" grants public access to view and download individual PDFs of select standards at no charge. Visit https://ieeexplore.ieee.org/browse/standards/get-program/page for details.

Safety limits for the protection of persons against the established adverse health effects of exposures to electric, magnetic, and electromagnetic fields in the frequency range 0 Hz to 300 GHz are presented in this standard. These exposure limits are intended to apply generally to persons permitted in restricted environments and to the general public in unrestricted environments. These exposure limits are not intended to apply to the exposure of patients by or under the direction of physicians and medical professionals, as well as to the exposure of informed volunteers in medical or scientific research studies, and might not be protective with respect to the use of medical devices or implants.

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.

This corrigendum was not published as an individual standard, but was incorporated in C95.1-2019

Technical corrections are addressed in this corrigendum. Figure 1 and Figure 2 in IEEE Std C95.1-2019 were found to be incorrect. They did not accurately portray the limits given in Table 2, Table 3, and Table 4. The figures were corrected with respect to frequency extent and breakpoints to be consistent with the tables.
