The Standards Committee that approved the code or standard was balanced to assure that individuals from competent and concerned i
42、nterests have had an opportunity to participate. The proposed Standard was made available for public review and comment that provides an opportunity for additional public input from industry, academia, regulatory agencies, and the public-at-large.(2) ASME does not “approve,” “rate,” or “endorse” any
43、 item, construction, proprietary device, or activity.(3) ASME does not take any position with respect to the validity of any patent rights asserted in connection with any items mentioned in this document, and does not undertake to insure anyone utilizing a standard against liability for infringement
44、 of any applicable letters patent, nor assume any such liability. Users of a standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, is entirely their own responsibility.(4) Participation by federal agency representati
