Subject: [c-a] UL labs and ethanol dispensing devices

I thought the following information from UL, on ethanol dispensing
devices, might be of interest.

Dear Valued Customer:

Effective immediately, Underwriters Laboratories Inc. is suspending
authorization to use UL Markings (Listing or Recognition) on
components for fuel dispensing devices that specifically reference
compatibility with alcohol blended fuels that contain greater than
15% alcohol (i.e. ethanol, methanol or other alcohols). Dispenser
components as they relate to use with traditional fuel blends (i.e.,
blended fuels containing 15% or less alcohols) are unaffected. In
all cases, acceptability of fuel dispensers for using alcohol-blended
fuels containing greater than 15% alcohol (e.g., E-85) remains at the
discretion of the Authority Having Jurisdiction.

Research indicates that the presence of high concentrations of
Ethanol or other alcohols within blended fuels makes these fuels
significantly more corrosive. This may result in the fuel chemically
attacking the materials used in fuel dispenser components, and may
ultimately degrade the dispenser's ability to contain the fuel.
While UL has no evidence of field issues related to this application,
we are suspending authorization to use the UL Mark on components used
in dispensing devices that will dispense any alcohol blended fuels
containing over 15% alcohol until updated certification requirements
are established and the effected components have been found to comply
with them.

Our engineers are actively reviewing current E-85 research and
meeting with industry and government experts to gather the
information required to draft the revised certification
requirements. UL anticipates that testing of E-85 dispenser
components will commence immediately following publication of UL's E-
85 certification requirements, as they pertain to the use of these
higher alcohol blended fuels on a dispenser system. We remain
committed to undertaking in an expeditious manner the thorough and
broad based effort necessary to develop the appropriate requirements
that will adequately address E-85 compatibility.

UL staff will be attending the PEI show in Las Vegas from October 9-
11, 2006 and will be available to address any of your questions. We
look forward to working with you in our effort to develop dispenser
and dispenser component requirements for the use of Ethanol based
fuels.
