NOTES for ANSI C95.1-198 :

(1) The squares of the field strengths or the power density, as applicable, are to be averaged over any six- minute period, and these time-averaged values should not exceed the values given in the table.

(2) For near field exposures, the only applicable protection guides are the mean squared electric and magnetic field strengths as given in the table above, columns 2 and 3. For convenience, these guides may be expressed as the equivalent plane wave power density, given in the fourth column of the table.

(3) Note that these guidelines have been replaced by the ANSI/IEEE C95.1-1992 (IEEE C95.1-1991) guidelines that follow. The FCC adopted the 1982 guidelines in 1985 for use in evaluating RF exposure. In 1993, the FCC proposed to adopt the new ANSI/IEEE guidelines. An FCC decision in that proceeding is expected by the middle of 1996.
