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
45、ve(s) or person(s) affiliated with industry is not to be interpreted as government or industry endorsement of this standard.(5) ASME accepts responsibility for only those interpretations of this document issued in accordance with the established ASME procedures and policies, which precludes the issu
46、ance of interpretations by individuals.(6) ASME issues written replies to inquiries concerning interpretation of technical aspects of this Standard. All inquiries regarding this Standard, including requests for interpretations, should be addressed to:Secretary, A112 Standards CommitteeThe American S

The request shouldcite the applicable edition of the Standard for which the interpretation is being requested.phrase the question as a request for an interpretation of a
48、 specific requirement suitable for general understanding and use, not as a request for an approval of a proprietary design or situation. The inquirer may also include any plans or drawings, which are necessary to explain the question; however, they should not contain proprietary names or information
49、.ASME procedures provide for reconsideration of any interpretation when or if additional information that might affect an interpretation is available. Further, persons aggrieved by an interpretation may appeal to the cognizant ASME Committee.Interpretations are published on the ASME Web site under the Committee Pages at http:/cstools.asme.org/ as they are issued.CSA Notes:(1) Use of the singular does not exclude the plural (and vice versa) when the sense allows.xiv December 2015 2015 ASSE International 2015 The American Society o
