IEEE C63.011 Approval of an American National Standard requires verification by ANSl that the requirements for due pro-cess,consensus,and other criteria for approval have been met by the standards developer.
Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agree-ment has been reached by directly and materially affected interests. Substantial agreement means muchmore than a simple majority, but not necessarily unanimity.Consensus requires that all views and objectionsbe considered and that a concerted effort be made toward their resolution.

Certain frequencies are designated by the Intermational telecommunication Union (ITU) for use as funda-mental frequencies for ISM equipment. At these frequencies unlimited power can be radiated because nolimits are set.However, linmits apply to harmonics and spurious radiation.The fundamental ISM frequenciesare shown in Table 1.The same frequencies can also be used in the United States and are listed in FCC Part18.IEEE C63.011 pdf download.
