Fuel Components and Systems Leak Tightness Specifications and Test Practices (or Methods)
Fuel Components and Systems Leak Tightness Specifications and Test Practices (or Methods)
This SAE recommended practice specifies a standard geometry leak channel to set the leak threshold and compare results from a variety of leak test technologies and test conditions. This practice applies to fuel system assemblies and components which have a risk of allowing regulated fuel or fuel vapors to continuously escape to atmosphere. A component or assembly tested to this standard has a zero HC leakage threshold because the selected leak channel (Equivalent Channel) will self-plug and will not emit measurable hydrocarbon liquid or vapors. Therefore this standard eliminates leaks as a source of evaporative emission. This practice was primarily developed for pressurized and non-pressurized fuel systems and components containing liquid hydrocarbon based fuels. This technical report is being Stabilized because it covers technology, products, or processes which are mature and not likely to change in the foreseeable future. The leak tightness requirements, test methods, and specifications are derived from current regulated fuel available in the market and hydrocarbon emission requirements (Zero HC Emission) which are not likely to get relaxed.
