Recent standards:

During 2014, the following TC95 standards were approved by the IEEE Standards Association Standards Board: IEEE C95.1-2345 (2014), “IEEE Standard for Military Workplaces—Force Health Protection Regarding Personnel Exposure to Electric, Magnetic, and Electromagnetic Fields, 0 Hz to 300 GHz; and IEEE C95.7-2014, “IEEE Recommended Practice for Radio Frequency Safety Programs, 3 kHz to 300 GHz”.

Current standards and standards under development by ICES TC95 (see Table 1 below).

SC1: Measurements & Calculations

SC1 has three active standards: 1) IEEE 1460-1996 “IEEE Guide for the Measurement of Quasi-Static Magnetic and Electric Fields,” which was reaffirmed in 2002 and listed active but the content has been incorporated into IEEE C95.3.1-2010; 2) IEEE C95.3-2002 “IEEE Recommended Practice for Measurements and Computations of Radio Frequency Electromagnetic Fields with Respect to Human Exposure to Such Fields, 100 kHz–300 GHz;” and 3) IEEE C95.3.1-2010 “IEEE Recommended Practice for Measurements and Computations of Electric, Magnetic, and Electromagnetic Fields with Respect to Human Exposure to such fields, 0 Hz to 100 kHz.”  Currently, SC1 is working to revise and combine the two standards into a single standard covering the 0 – 300 GHz frequency band (Draft Recommended Practice for Measurements and Computations of Electric, Magnetic and Electro-magnetic Fields with Respect to Human Exposure to Such Fields, 0 Hz to 300 GHz).

 

SC2: Warning Signs/Hazard Communication

SC2 has two active standards: 1) IEEE C95.2-1999 “IEEE Standard for Radio Frequency Energy and Current Flow Symbols,” which was reaffirmed in 2005.  The content of this standard is stable and a revision is not expected in the near future. 2) IEEE C95.7-2014 “Recommended Practice for Radio Frequency Safety Programs – 3 kHz to 300 GHz.”  IEEE C95.7-2014, a revision of IEEE C95.7-2005, is companion standard for implementing an RF safety program in compliance with  the exposure standard IEEE C95.1-2005.

SC3: Exposure Limits for 0-3 kHz

This subcommittee, organized in 1991 with 75 members from 11 countries, developed IEEE C95.6-2002 “IEEE Standard for Safety Levels with Respect to Human Exposure to Electromagnetic Fields, 0 to 3 kHz” (reaffirmed in 2007).  The exposure limits in this standard were derived to minimize effects associated with electrostimulation. SC3 is now working jointly with SC4 to revise and combine the low frequency standard C95.6 with the high frequency standard C95.1.

SC4: Exposure Limits for 3 kHz-300 GHz

This subcommittee has the longest history in developing RF exposure standards. Its predecessor published the first RF exposure limits in 1966 as USAS C95.1-1966. The current version is IEEE C95.1-2005 “IEEE Standard for Safety Levels with Respect to Human Exposure to Radio Frequency electromagnetic Fields, 3 kHz to 300 GHz.”  In July 2009, IEEE and the NATO Standardization Agency signed an agreement to develop a standard to replace NATO STANAG 2345 MED (EDITION 3) – “Evaluation and Control of Personnel Exposure to Radio Frequency Fields – 3 kHz to 300 GHz.”  SC3 and SC4 worked jointly to combine IEEE C95.6-2002 and IEEE C95.1-2005—published as IEEE C95.1-2345-2014 “IEEE Standard for Military Workplaces—Force Health Protection Regarding Personnel Exposure to Electric, Magnetic, and Electromagnetic Fields, 0 Hz to 300 GHz.”

Currently SC3 and SC4 continue the work of revising and combining IEEE C95.6-2002 and IEEE C95.1-2005 into a single standard.  Review of literature published after 2003 will be the main immediate activity of the subcommittees.

SC5: Electro-Explosive Devices

SC5 has one standard, IEEE C95.4-2002 “IEEE Recommended Practice for Determining Safe Distances from Radio Frequency Transmitting Antennas When Using Electric Blasting Caps During Explosive Operations,” which was reaffirmed in 2008.  SC5, after several dormant years, has resumed its activity to investigate broadening the scope and harmonizing the standard with other international standards.

SC6: EMF Dosimetry Modeling

The goal of SC6 is to resolve uncertainties related to numerical models that calculate electric fields induced within the body by external electromagnetic fields or contact currents, as well as thresholds of excitation of CNS and PNS neurons in response to the spatial and temporal characteristics of the induced fields. Experimental verification will be relevant. The subcommittee is expected to produce position papers that will guide the development and revision of human exposure limits, identify procedures to determine compliance with published limits, and identify research needs. Although the full range of frequencies in ICES standards (0 Hz to 300 GHz) will be covered, initial efforts will focus on frequencies below 100 kHz where electrostimulation effects are dominant.
*Free C95.1 standards: Under the sponsorship of US Air Force, Army, and Navy, several IEEE C95 standards are available at no cost through the “IEEE Get Program (http://standards.ieee.org/about/get/index.html).
