Underwriters Laboratories E85 Fuel Dispenser Listing
Underwriters Laboratory (UL) establishes safety requirements and procedures for complete E85 (85% ethanol, 15% gasoline) fuel dispenser systems. In 2006, UL suspended its certifications (listings) for individual parts being used in E85 dispensers and, in 2007, published new listings for E85 dispenser systems. The new listings cover whole dispensing systems rather than individual components to ensure material compatibility, adherence to fire safety codes, and consistency across related products. The U.S. Department of Energy (DOE) partnered with UL to accelerate the E85 dispenser evaluation process. Some jurisdictions will grant a waiver or variance for alternative equivalent dispensers for dispensing E85, but are not UL certified. UL Status and ProcessThe status of UL testing and progress toward certification is constantly changing. Currently, dispensers sold in the marketplace are UL listed for blends up to E10 (10% ethanol, 90% gasoline). UL has developed testing requirements for E85 dispensers and has received some for testing. Recently, UL developed a new set of requirements for mid-level ethanol blends. There are now three fuel dispenser certification paths for new equipment:
UL is not affiliated with the U.S. Department of Energy and does not endorse the Web site. The time it takes to complete the testing and certification process depends on the how well the equipment performs. For more information, read the updates in the box above or see:
New Product Certification and TestingFor new products, individual manufacturers, industry groups, or insurance underwriters usually approach a standards development organization (SDO) or testing agency, like UL, well in advance of new product introductions and work together to develop rigorous safety standards and testing procedures used to evaluate the product. The group of manufacturers and industry partners interested in introducing the product to the market usually bears the cost of standards development and subsequent testing work. For more information on how the certification process usually works, see About UL Mark Product Certification. Fuel Dispenser Fire Safety CodesEach authority adopts codes and standards for its jurisdiction. These codes may be set and enforced on a state, regional, or local level. Two organizations, the National Fire Protection Association (NFPA) and the International Code Council (ICC), provide standard codes that are accepted or modified to meet local requirements. UL accommodates these codes in their listing process.
Waivers and VariancesMany jurisdictions allow an alternate equivalent dispenser design to be submitted for approval. Each jurisdiction has its own process and discretion in granting variances or waivers to approve designs not UL certified. In the NFPA 30A Code, it addresses the process for approving equivalent equipment:
ContactsFor questions about waivers or variances, contact your local state energy office or a Clean Cities coordinator. State Letters and DocumentsMany states have granted variances or waivers. Refer to the following letters from state officials and other state documents about E85.
