Test Procedure to Measure the Fuel Permeability of Materials by the Cup Weight Loss Method

2018-12-12
CURRENT
J2665_201812
This test standard covers the procedure for measuring the permeation of fuel or fuel surrogates through test samples of elastromeric, plastic, or composite materials, up to about 3 mm thick. The method involves filling a test cup with the test fluid (fuel or fuel surrogate), sealing test sample over the open end of the cup, and then placing the sealed container into an oven at the desired test temperature and measuring the weight loss over time. Permeation rates are calculated from the rate of weight loss and the exposed area of the test sample.

Test Method to Measure Fluid Permeation of Polymeric Materials by Speciation

2018-12-12
CURRENT
J2659_201812
This test method described in this document covers a procedure to speciate that is, to determine the amounts of each different fuel constituent that permeates across sheets, films or slabs of plastic materials. One side of the sheet is meant to be in contact with either a liquid test fuel or a saturated test fuel vapor, the other side is meant to be exposed to an environment free of fuel. The test fuel can either be a mixture of a small (usually smaller than ten) number of hydrocarbon, alcohol and ether constituents or it can be a sample of a real automotive fuel, e.g., one that may contain hundreds of different constituents. Furthermore, Appendix A contains guidelines to speciate evaporative emissions from finished fuel system components such as fuel lines, fuel filler pipes, fuel sender units, connectors and valves.

Fuel Components and Systems Leak Tightness Specifications and Test Practices (or Methods)

2018-11-08
WIP
J2973
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.

Test Procedure to Determine the Hydrocarbon Losses from Fuel Tubes, Hoses, Fittings, and Fuel Line Assemblies by Recirculation

2018-08-13
WIP
J1737
This SAE Recommended Practice is intended for the determination of the losses of hydrocarbon fluids, by permeation through component walls as well as through 'microleaks' at interfaces of assembled components while controlling temperature and pressure independently of each other. This is achieved in a recirculating system in which liquids which are transported through walls and joints are collected by a controlled flow of nitrogen (dry) and adsorbed by activated charcoal.

J1645
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: o Flowing fuel in the fuel delivery system o Flowing fuel being dispensed to the vehicle while it is being fueled

WIP
J2045
This SAE Standard encompasses the recommended minimum requirements for non-metallic tubing and/or combinations of metallic tubing to non-metallic tubing assemblies manufactured as liquid- and/or vapor-carrying systems designed for use in gasoline, alcohol blends with gasoline, or diesel fuel systems. This SAE Standard is intended to cover tubing assemblies for any portion of a fuel system which operates above –40 °C (–40 °F) and below 115 °C (239 °F), and up to a maximum working gage pressure of 690 kPa (100 psig). The peak intermittent temperature is 115 °C (239 °F). For long-term continuous usage, the temperature shall not exceed 90 °C (194 °F). It should be noted that temperature extremes can affect assemblies in various manners and every effort must be made to determine the operating temperature to which a specific fuel line assembly will be exposed, and design accordingly.

WIP
J2744
This document presents the requirements for a build-in service port to be used in vehicles intended to comply with Enhanced Evaporative Emission Requirements. The primary function of the Service Port (Valve Assembly-Evaporative Emission Canister Purge Harness Service) is to provide non-destructive access to the evaporative emissions system to enable testing of the integrity of the system. The Service Port is used to introduce air pressure or fuel vapors into, or evacuate them out of, the system. This access may be used for the following evaluations: Evaporative System Certifications Canister Loading and Pumping End-of-line Testing System Integrity Service (e.g. OBD MIL on) Leak Location and Repair Verification In-Use Compliance Testing Canister Loading and Purging Inspection/Maintenance Testing System Integrity and Purge Check

This SAE recommended practice provided standard dimensions for liquid fuel dispenser nozzle spouts and a system for differentiating between nozzels that dispense liquid fuel into vehicles with Spark Ignition (SI) Engines and compression Ignition (CI) Engines for land vehicles. Current legal definitions only distinguish between "UNLEADED Fuel" and "All Other Types of Fuel." These definitions are no longer valid. This document establishes a new set of definitions that have practical application to current automobile liquid fuel inlets and liquid fuel dispenser nozzle spouts.

Test Procedure to Determine the Hydrocarbon Losses from Fuel Tubes, Hoses, Fittings, and Fuel Line Assemblies by Recirculation

2013-05-14
CURRENT
J1737_201305
This SAE Recommended Practice is intended for the determination of the losses of hydrocarbon fluids, by permeation through component walls as well as through "microleaks" at interfaces of assembled components while controlling temperature and pressure independently of each other. This is achieved in a recirculating system in which elements of a test fuel that permeate through the walls of a test specimen and migrate through the interfaces are transported by a controlled flow of dry nitrogen to a point where they are measured. That measurement point is a device, such as a canister containing activated charcoal or other means of collection or accumulation where the hydrocarbon losses are then measured by weight change or analyzed by some other suitable means.
