DISCLAIMER AND COPYRIGHT
The American Gas Association’s (AGA) Operations and Engineering Section provides a forum
for industry experts to bring collective knowledge together to improve the state of the art in the
areas of operating, engineering and technological aspects of producing, gathering, transporting,
storing, distributing, measuring and utilizing natural gas.
Through its publications, of which this is one, AGA provides for the exchange of information
within the gas industry and scientific, trade and governmental organizations. Each publication is
prepared or sponsored by an AGA Operations and Engineering Section technical committee.
While AGA may administer the process, neither AGA nor the technical committee independently
tests, evaluates or verifies the accuracy of any information or the soundness of any judgments
contained therein.
AGA disclaims liability for any personal injury, property or other damages of any nature
whatsoever, whether special, indirect, consequential or compensatory, directly or indirectly
resulting from the publication, use of or reliance on AGA publications. AGA makes no guaranty
or warranty as to the accuracy and completeness of any information published therein. The
information contained therein is provided on an “as is” basis and AGA makes no representations
or warranties including any expressed or implied warranty of merchantability or fitness for a
particular purpose.
In issuing and making this document available, AGA is not undertaking to render professional or
other services for or on behalf of any person or entity. Nor is AGA undertaking to perform any
duty owed by any person or entity to someone else. Anyone using this document should rely on
his or her own independent judgment or, as appropriate, seek the advice of a competent
professional in determining the exercise of reasonable care in any given circumstances.
AGA has no power, nor does it undertake, to police or enforce compliance with the contents of
this document. Nor does AGA list, certify, test or inspect products, designs or installations for
compliance with this document. Any certification or other statement of compliance is solely the
responsibility of the certifier or maker of the statement.
AGA does not take any position with respect to the validity of any patent rights asserted in
connection with any items that are mentioned in or are the subject of AGA publications, and
AGA disclaims liability for the infringement of any patent resulting from the use of or reliance on
its publications. Users of these publications 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.
Users of this publication should consult applicable federal, state and local laws and regulations.
AGA does not, through its publications intend to urge action that is not in compliance with
applicable laws, and its publications may not be construed as doing so.
This report is the cumulative result of years of experience of many individuals and organizations
acquainted with the measurement of natural gas. However, changes to this report may become
necessary from time to time. If changes to this report are believed appropriate by any
manufacturer, individual or organization, such suggested changes should be communicated to
AGA by completing the last page of this report titled, “Form for Proposal on AGA Report No.
