UL Subject 2267 Standard
for Fuel cell Power System For Installation in Industrial Electric Trucks |
|
|
Scope |
The requirements cover fuel cell power systems currently
noted as intended to be installed in type E, industrial trucks used in
locations as defined in the Fire Safety Standard for Powered Industrial
Trucks including Type Designations, Areas of Use, Conversions, Maintenance
and Operations NFPA 505, and the National Electrical Code NFPA 70. The scope
only covers those systems that incorporate a permanently mounted pressure
vessel containing compressed hydrogen gas for designs that are fueled without
the pressure vessel being removed from the industrial truck (on board
fueling). At this time, the standard is limited to systems with maximum pressures
of 25 MPa or 35MPa. |

Status |
The
standard was published in May 2006 as an ANSI standard, and is available
through UL. The document was recently revised to address those areas of UL
2267 affecting high pressure fuel containment to appropriately address safety
concerns of current technology. Specific revisions to address the following
concerns were recently completed: a. Develop cycling and other tests
of high pressure systems as needed, b. Address instructions and
markings, and c. Address End of Life Criteria These revisions include:
