29、th IEEE or IEEE SA.However,IEEE does not provide interpretations,consulting information,or advice pertaining to IEEE Standards documents.Suggestions for changes in documents should be in the form of a proposed change of text,together withappropriate supporting comments.Since IEEE standards represent
30、 a consensus of concerned interests,it isimportant that any responses to comments and questions also receive the concurrence of a balance of interests.For this reason,IEEE and the members of its Societies and Standards Coordinating Committees are not able toprovide an instant response to comments,or
31、 questions except in those cases where the matter has previouslybeen addressed.For the same reason,IEEE does not respond to interpretation requests.Any person who wouldlike to participate in evaluating comments or in revisions to an IEEE standard is welcome to join the relevantIEEE working group.You
