What is UL?
UL stands for Underwriter Laboratories, a third-party certification company that’s been around for over a century. They certify products with the aim to make the world a safer place for both workers and consumers. Besides testing, they set industry standards to follow when innovating new products.
UL Elastomers for Fuel Handling
What are the UL Seal Regulatory & Standards for Fuel Handling?
UL2586 - Standard for Hose Nozzle Valves
- UL2586A for Gasoline and Gasoline/Ethanol Blends with Nominal Ethanol Concentrations up to 85 Percent (E0 - E85)
- UL2586C for Power-Operated Dispensing Devices for Diesel Exhaust Fluid
UL87 - Standard for Power-Operated Dispensing Devices for Petroleum Products
- UL2586A for Gasoline and Gasoline/Ethanol Blends with Nominal Ethanol Concentrations up to 85 Percent (E0 - E85)
- UL2586B for Diesel Fuel, Bio-diesel Fuel, Diesel/Bio-diesel Blends with Nominal Bio-diesel Concentrations up to 20 Percent (B20), Kerosene, and Fuel Oil
- UL2586C for Power-Operated Dispensing Devices for Diesel Exhaust Fluid
UL 50E - Enclosures for Electrical Equipment, Environmental Considerations
- Cellular gasket materials rated “UL 50E (continuous compression)” have been investigated for use where they are under compression over the life of their use (e.g., gaskets used in pilot lights, pushbuttons, selector switches, viewing windows, disconnect operators).
- Cellular gasket materials rated “UL 50E (periodic recompression)” comply with UL 50E Compression Test requirements. They may be used in continuous compression applications, but have additionally been investigated for use where they are subject to prolonged periods of compression followed by occasional, short periods of relaxation where the seal provided by the gasket may be broken during the life of the application and, after each such occurrence, the gasket is expected to provide the same seal when recompressed (e.g., gaskets used as the sealing means in the perimeter of doors and covers)
- Solid (noncellular) gasket materials rated “UL 50E” are considered suitable for either continuous compression or periodic recompression applications.
