Updating of AGA and NFPA Standards
Users of NFPA codes, standards, recommended practices, and guides (“NFPA Standards”) and AGA Z223.1 should be aware
that these documents may be superseded at any time by the issuance of new editions or may be amended from time to time
through the issuance of Tentative Interim Amendments or corrected by Errata. An official NFPA or AGA document at any point
in time consists of the current edition of the document together with any Tentative Interim Amendments and any Errata then
in effect. In order to determine whether a given document is the current edition and whether it has been amended through the

such as the National Fire Codes

Interpretations of AGA and NFPA Standards
A statement, written or oral, that is not processed in accordance with the interpretation procedures of the Z223 Committee or
Section 6 of the Regulations Governing the Development of NFPA Standards shall not be considered the official position of the
Z223 Committee or the NFPA or any of their respective Committees and shall not be considered to be, nor be relied upon as, a
Formal Interpretation.
Patents
Neither the AGA nor the NFPA take any position with respect to the validity of any patent rights referenced in, related to, or
asserted in connection with an AGA or NFPA document. The users of AGA and NFPA documents bear the sole responsibility
for determining the validity of any such patent rights, as well as the risk of infringement of such rights, and the AGA and NFPA
disclaim liability for the infringement of any patent resulting from the use of or reliance on AGA and NFPA documents.
AGA and NFPA adhere to the policy of the American National Standards Institute (ANSI) regarding the inclusion of patents
in American National Standards (“the ANSI Patent Policy”), and hereby give the following notice pursuant to that policy:
NOTICE: The user’s attention is called to the possibility that compliance with an AGA or NFPA document may require
use of an invention covered by patent rights. AGA and NFPA take no position as to the validity of any such patent rights
or as to whether such patent rights constitute or include essential patent claims under the ANSI Patent Policy. If, in
connection with the ANSI Patent Policy, a patent holder has filed a statement of willingness to grant licenses under these
rights on reasonable and nondiscriminatory terms and conditions to applicants desiring to obtain such a license, copies of
such filed statements can be obtained, on request, from NFPA. For further information, contact the NFPA at the address
listed below.

in compliance with applicable laws, and this document may not be construed as doing so.
