Fuel Systems and Components - Electrostatic Charge Mitigation
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
This 2011 version of SAE Recommended Practice J1645 includes some editorial updates of the August, 2006 publication MAIN TEXT based on new or corrected information. The APPENDICES have been completely reorganized and in some cases significantly revised in order to provide more coherent information regarding this complex subject. The reasons for the update of the APPENDICES were a significant amount of new information about testing procedures and acceptance criteria. Incorporating these areas of improved information caused changes so numerous that they cannot be individually noted. This version of J1645 replaces the previous version.
