Test Method to Measure Fluid Permeation of Polymeric Materials by Speciation

Fuel Systems Standards Committee
  • Ground Vehicle Standard
  • J2659_201812
  • Current
Published 2018-12-12 by SAE International in United States

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.

Methods for Determining Physical Properties of Polymeric Materials Exposed to Hydrocarbon Fuels or Their Surrogates and Their Blends with Oxygenated Additives

Fuel Systems Standards Committee
  • Ground Vehicle Standard
  • J1748_201808
  • Current
Published 2018-08-13 by SAE International in United States
This SAE Recommended Practice applies to determining worst-case fuel or test fluid surrogate, conditioning test specimens in worst-case fuel(s)/surrogate(s) prior to testing, individual tests for properties of polymeric materials exposed to oxygenate fuel/surrogate mixtures with additives. The determination of equilibrium, as well as typical calculations are also covered.

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

Fuel Systems Standards Committee
  • Ground Vehicle Standard
  • J2973_201402
  • Current
Published 2014-02-05 by SAE International in United States
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.

Standard for Protective Covers for Gasoline Fuel Line Tubing

Fuel Systems Standards Committee
  • Ground Vehicle Standard
  • J2027_201305
  • Current
Published 2013-05-28 by SAE International in United States
This SAE Standard includes performance requirements for protective covers for flexible, non-metallic fuel tubing. Ultimate performance of the protective cover may be dependent on the interaction of the fuel tubing and protective cover. Therefore, it is recommended that tubing and cover combinations be tested as an assembly, where appropriate, to qualify to this document.

Recommended Methods for Conducting Corrosion Tests in Hydrocarbon Fuels or Their Surrogates and Their Mixtures with Oxygenated Additives

Fuel Systems Standards Committee
  • Ground Vehicle Standard
  • J1747_201305
  • Current
Published 2013-05-14 by SAE International in United States
This SAE Recommended Practice presents standardized test methods developed for use in testing with hydrocarbon fuels or their surrogates and those same fuels when blended with oxygenated fuel additives. Hydrocarbon fuels include Gasoline and Diesel fuel or their surrogates described in SAE J1681. Oxygenated additives include Ethanol, Methanol Methyl Tertiary Butyl Ether (MTBE) and Fatty Acid Methyl Esters (FAME or Biodiesel).

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

Fuel Systems Standards Committee
  • Ground Vehicle Standard
  • J1737_201305
  • Current
Published 2013-05-14 by SAE International in United States
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.

Rated (Advertised) Fuel Capacity - Passenger Car, Multi-Purpose Passenger Vehicles, and Light Duty Trucks

Fuel Systems Standards Committee
  • Ground Vehicle Standard
  • J398_201211
  • Current
Published 2012-11-01 by SAE International in United States
This recommended practice provides a method for establishing the rated or advertised fuel capacity for a vehicle utilizing liquid fuel at atmospheric pressure. It applies to passenger cars, multi-purpose passenger vehicles and light duty trucks (10 000 lb (4536 kg) maximum GVW), (Ref. SAE J1100). It also includes a standardized procedure for creating a full tank when another test requires that condition as a starting point. It is intended as a guide toward standard practice and is subject to change to keep pace with experience and technical advances.

Performance Requirements for Fuel System Tubing Assemblies

Fuel Systems Standards Committee
  • Ground Vehicle Standard
  • J2045_201211
  • Current
Published 2012-11-01 by SAE International in United States
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. The applicable SAE standards should be referenced when designing liquid-carrying and/or vapor-carrying systems which are described in this document. Wherever possible or unless stated otherwise, systems tested to this document shall be in the final…

Fuel Filler Pipe Assembly Design Practice to Meet Low Evaporative Emission Requirements

Fuel Systems Standards Committee
  • Ground Vehicle Standard
  • J2599_201208
  • Current
Published 2012-08-14 by SAE International in United States
This SAE Recommended Practice covers design and evaluation of the entire gasoline filler pipe assembly used on cars and light trucks with respect to compliance with CARB (California Air Resources Board) LEV II (meeting or exceeding EPA Tier 2 and EU Stage-5 evaporative emissions requirements). It is limited to an assembly which is joined to the fuel tank using either a hose, Quick Connect Coupling, or a grommet type sealing device. The Design Practice covers the filler cap, filler pipe, filler pipe assembly to tank hose, and filler pipe assembly to tank grommet or spud. It includes recommendations for design of components and assemblies intended to perform successfully in evaporative emission SHED (Sealed Housing for Evaporative Determination) tests, based on best practices known at the time of release.
