(a) In addition to NFPA 52 §5.4.5.1 and NFPA 55 §7.1.6.1:
  (1) Compressed natural gas (CNG) shall not be introduced into any ASME container unless the container is equipped with an original nameplate or at least one of the following nameplates permanently attached to the container or has the required information stamped directly on the vessel.
    (A) A duplicate nameplate is an additional ASME container nameplate issued by the original manufacturer with duplicate information as the original nameplate and clearly marked as a duplicate nameplate but installed in a remote location.
    (B) A modification (or alteration) nameplate is a nameplate issued and affixed by an ASME Code facility including only partial information applicable to a modification or alteration performed on that container.
    (C) A replacement nameplate is a nameplate including the identical information as the original nameplate and identified as a replacement nameplate, but issued and affixed by the original manufacturer or its successor company or companies when the original nameplate is lost or illegible.
  (2) Nameplates on ASME containers manufactured on or after November 1, 1994, shall be stainless steel.
  (3) If the nameplate is attached, it shall be attached in a manner that will minimize corrosion of the nameplate or its attachments or that will not contribute to the corrosion of the container.
(b) If the nameplate is attached directly to the container, the nameplate thickness shall be sufficient to resist distortion due to the application of markings and fusion welding.
(c) Container nameplates shall be stamped or etched with the following information in legible characters:
  (1) the mark or symbol approved by ASME indicating compliance with the provisions of the ASME Pressure Vessel Code;
  (2) the name and address of the manufacturer;
  (3) the capacity of the container in standard cubic feet;
  (4) the maximum allowable working pressure of the container in pounds per square inch (psi);
  (5) the thickness of the material used in both the shell and heads;
  (6) the overall length of the container, the outside diameter of the container, and the dish radius of the heads;
  (7) the serial number of the container; and
  (8) the date of manufacture.
(d) Nameplates attached to or markings on the container shall remain visible after installation of the containers.
(e) Containers manufactured prior to November 1, 1994, which may have corroded or rusted nameplates shall have the following minimum information readable on the manufacturer's nameplate:
  (1) name of the container manufacturer;
  (2) manufacturer's serial number;
  (3) working pressure; and
  (4) capacity.
(f) AFS may remove a container from CNG service or require ASME acceptance of a container at any time if AFS determines that the nameplate or stamped information, in any form defined in subsection (a) of this section, is loose, unreadable, or detached, or if it appears to be tampered with or damaged in any way and does not contain at a minimum the items defined in subsection (c) or (e) of this section as applicable.
