This SAE Surface Vehicle Recommended Practice deals with electrostatic charge phenomena that may occur in automotive fuel systems and applies to the following: Fuels that are in a liquid state at ambient temperatures and atmospheric pressures and are contained in vehicle fuel tanks that operate at or near atmospheric pressure. This includes gasoline and diesel fuels, as well as their blends with additives such as alcohols, esters, and ethers, whether the additives are petroleum based or bio-fuel based. The group of components that comprise the fuel system (in contact and not in contact with fuels). Other components in proximity to the fuel system that may be affected by electrostatic fields caused by the fuel system. Electrostatic phenomena that arise from, or are affected by, the following aspects of vehicle or fuel system operation: ○ Flowing fuel in the fuel delivery system. ○ Flowing fuel being dispensed to the vehicle while it is being fueled.

The purpose of this SAE Recommended Practice is to provide an explanation of electrostatic charge phenomena as they relate to automotive fuel systems and how those phenomena should be handled if they develop. This document is limited to the group of components that are known as the fuel system and only those that handle liquid fuel in one of two situations: operation of the fuel delivery system and refueling of the vehicle. This is a collection of ideas and generalities that are summarized from literature and presentations, inferred from some laboratory experimentation and summarized from experiences within the automotive industry as interpreted by the Electrostatics Subcommittee of the SAE Fuel Lines and Fittings Standards Committee. Some of the discussions are simplified. If users of this document need some further technical information, experts should be consulted or the references cited here should be examined directly.

The purpose of this SAE Information Report is to provide a summary of the electrostatic charge phenomenon (as it relates to an automotive fuel system) and how that phenomenon could be handled if it develops. The "fuel system" that is the subject of this document is the group of components used during the operation of the vehicle (tank, filler neck, pump, filter, lines, connectors, etc.). Electrostatic charge that may arise during refueling is also included. It is very important to note that this is a collection of ideas and generalities that are summarized from literature and presentations, inferred from some laboratory experimentation, and interpreted by the Electrostatics Subcommittee of the SAE Fuel Lines and Fittings Standards Committee. Some of the discussions are simplified. If more technical information is needed by users of this document, experts should be consulted or literature should be examined directly.
