The tough safety
standards for fuel nozzle valves that took effect in late April didn’t happen
overnight. Underwriters Laboratories (UL), which has developed product safety
standards for more than 100 years, worked through a lengthy process to address
the reality of increased ethanol content in gasoline. E10 is in 90 percent of
U.S. gas at the moment. But E15 is increasingly available around the country.
“I can tell
you from my experience that it was the manufacturers who were very interested
in us doing that. It wasn’t our idea and we were not telling them what to do.
They were supportive and maybe even initiated some of this because they wanted
their equipment to be safe,” John Drengenberg, UL Engineer and Consumer Safety
Director said in an interview.
Standards
Technical Panel
The task to
recommend standards for nozzles to safely handle ethanol blended with gasoline
at rates higher than E10 was assigned to a UL Standards Technical Panel. This
diverse group reviews and votes on proposals prior to publication. The focus in
this instance was to account for the way ethanol concentrations affect components
like check valves, diaphragms, seals and springs.
“The standards are vetted through a committee where we have representatives of government, industry, and safety all sitting at the same table. Standards development is a process that involves a lot of people and is something UL has been doing for years,” Drengenberg said.

Husky:
First Major Manufacturer with Nozzles Listed under UL 2586
One test protocol that emerged from the technical panel was
using ATS fuels A, Z, H and IRM fuel 903 to simulate what high concentrations
of ethanol do to nozzle components. Husky Corporation
engineers invested years coming up with design configurations that could pass
this and other rigorous tests to meet the new standards. In many cases, the
change required the use of more costly internal components that could meet the
requirements.
“Our standards process is give and take. It’s working with
the industry, not imposing things on the industry,” Drengenberg said.
Husky was the first major nozzle manufacturer to have its full
listing card published
on the UL website prior to the effective date for the new UL 2586 standards.
