UL Offers Certification for Dispensers of E25 Blends

Underwriters Laboratories (UL), a world leader in product safety testing services, has a new certification path for fuel dispensers for mid-level ethanol blends up to E25.

With the new certification path, manufacturers of dispensers, assemblies and components now have three certification options to choose from to balance market needs and provide maximum flexibility as advances are made in the fuel industry.

"The development of renewable energies continues to evolve at a rapid pace and we understand the need for future innovation, cost effectiveness and getting product to market quickly; however, public safety must remain paramount," said Jeff Smidt, general manager of Global Energy Business for UL.

For 115 years, UL has leveraged a transparent process to regularly develop and review product safety standards and requirements. Requirements are changed, added or retired as global safety needs advance. As such, the new mid-level certification path was proactively developed and presented in July to dispenser and component manufacturers. The meeting addressed the fuel dispensing market and potential market developments. As of Aug. 3, UL is providing three certification paths for dispensers of pre-blended fuels. They are:

  • UL 87 for gasoline and ethanol fuel blends up to E10
  • The established requirements of Subject 87A-E85, which address gasoline and ethanol fuel blends up to E85
  • The new certification path in Subject 87A-E25, which addresses gasoline and mid-level ethanol fuel blends up to E25
"We set the new requirements for fuel dispensers based on research of multiple blend concentrations and their effects on components," said Smidt. "There is increased potential for different types of damage to materials and components at blends above E25 and, as a result, there are more stringent requirements for dispensers for use with these higher blend levels. This new mid-level option, up to E25, provides another certification path and can help facilitate the distribution of ethanol blends in the market."
