The standards developed within IEEE represent a consensus of the broad expertise on thesubject within the Institute as well as those activities outside of IEEE that have expressed an inter-est in participating in the development of the standard.Use of an IEEE Standard is wholly vol

The existence of an IEEE Standard does not implythat there are no other ways to produce, test, measure, purchase, market, or provide other goods andservices related to the scope of the IEEE Standard. Furthermore, the viewpoint expressed at thetime a standard is approved and issued is subject

Every IEEE Standard is sub-jected to review at least every ve years for revision or reafrmation. When a document is morethan ve years old and has not been reafrmed, it is reasonable

9、 to conclude that its contents,although still of some value, do not wholly reect the present state of the art.

11、When the need for interpretations is brought to the attention ofIEEE, the Institute will initiate action to prepare appropriate responses. Since IEEE Standards rep-resent a consensus of all concerned interests, it is important to ensure that any interpretation hasalso received the concurrence of a b

For this reason, IEEE and the members of itssocieties and Standards Coordinating Committees are not able to provide an instant response tointerpretation requests except in those cases where the matter has previously received formalconsideration.
