TC95 Subcommittee 4: Safety Levels with Respect to Human Exposure, 3 kHz - 300 GHz
Subcommittee 4 has responsibility for the C95.1 standard. This standard was first published as a USASI standard in 1966 and revisions were published as ANSI standards in 1974 and 1982. In 1991 a revision was published as an IEEE standard. It was reaffirmed in 1997, a corrigendum published in 1999 and an amendment in 2004. The latest revision, C95.1-2005 was approved by the SASB at the September 2005 meeting and published in April 2006. The revision is the result of a major effort by SC-4 to fully review and evaluate the relevant scientific literature. An amendment is being considered to clarify language that could not be clarified during final review without substantive changes. A PAR will be submitted for this amendment following the November 2007 meeting. A PAR for the revision of C95.1 with an extended scope to cover the frequency range of 0-300 GHz will be submitted next year. IEEE C95.6 will be incorporated into this revision; following approval, C95.6 will be withdrawn. Plans are underway to develop a short-course that explains the differences between the 2005 and 1991 standards and describes the implementation of the safety limits.
