Develop revised maximum permissible exposure (MPE) levels for exposures to electromagnetic fields for exposures in controlled and uncontrolled environments at frequencies between 3 kHz and 300 Ghz. The MPEs will be expressed in terms of quantifiable parameters such as electric-field strength, magnetic-field strength, power density, induced current and contact current. Exclusions and peak limits for pulsed fields will be included.

This document specifies protocols and test procedures for the reproducible and repeatable measurement of the conservative exposure peak spatial average SAR (psSAR) induced inside a simplified model of the head and the body by radio-frequency (RF) transmitting devices, with a defined measurement uncertainty.

This document is employed to evaluate SAR compliance of different types of wireless communication devices used next to the ear, in front of the face, mounted on the body, operating in conjunction with other RF-transmitting, non-transmitting devices or accessories (e.g. belt-clips), or embedded in garments. The applicable frequency range is from 4 MHz to 10 GHz. Devices operating in the applicable frequency range can be tested using the phantoms and other requirements defined in this document. The device categories covered include, but are not limited to, mobile telephones, cordless microphones, and radio transmitters in personal, desktop and laptop computers, for multi-band operations using single or multiple antennas, including push-to-talk devices. This document can also be applied for wireless power transfer devices operating above 4 MHz. This document does not apply to implanted medical devices. read less
This document provides guidance for the application of computerized operating procedure systems (COPS). This guidance concerns the design (i.e., form and function) and use of COPS. In general, this guide does not provide guidance for the technical content of the operating procedures being presented except as needed to address unique aspects of procedure implementation on COPS. Software tools that can be described as computerized procedures but reside outside the control room (such as might be used for maintenance or testing) are also beyond the scope of this document.
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.
This International Standard specifies computational procedures using Finite-Difference Time-Domain (FDTD) and Finite Element Methods (FEM) to assess the peak and spatial-averaged power density relevant to the human exposure of the human head or body from devices operating between 6 GHz and 300 GHz.

This document specifies protocols and test procedures for repeatable and reproducible measurements of power density (PD) that provide conservative estimates of exposure incident to a human head or body due to radio-frequency (RF) electromagnetic field (EMF) transmitting communication devices, with a specified measurement uncertainty.

This standard specifies the assessment methods to evaluate compliance of stationary and dynamic wireless power transfer systems with electromagnetic human exposure guidelines (external electric and magnetic fields, internal specific absorption rate (SAR), induced electric fields or current density including contact currents).

This part of IEC/IEEE 62704 describes the concepts, techniques, and limitations of the finite element method (FEM) and specifies models and procedures for verification, validation and uncertainty assessment for the FEM when used for determining the peak spatial-average specific absorption rate (psSAR) in phantoms or anatomical models. It recommends and provides guidance on the modelling of wireless communication devices, and provides benchmark data for simulating the SAR in such phantoms or models. This document does not recommend specific SAR limits because these are found elsewhere (e.g. in IEEE Std C95.1 [1]1 or in the guidelines published by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) [2]).
