The Consensus Committee that approved the code or standard was balanced to assure that individuals from competent and concerned interests have had an opportunity to participate. The proposed code or standard was made available for public review and comment

4、 which provides an opportunity for additional public input from industry, academia, regulatory agencies, and the public-at-large.
