D4865-23 – Standard Test Method Technical Guide
ASTM D4865-23 is the Standard Guide for Generation and Dissipation of Static Electricity in Petroleum Fuel Systems. It describes how static electricity may be generated in petroleum fuel systems, the types of equipment conducive to charge generation, and methods for the safe dissipation of such charges. A foundational premise is that fires and explosions require a flammable hydrocarbon/air mixture and an ignition source from accumulated static electricity. The guide is issued under the fixed designation D4865 and is under the jurisdiction of Committee D02 on Petroleum Products, Liquid Fuels, and Lubricants.
