Dispenser Nozzle Spouts for Liquid Fuels Intended for Use with Spark Ignition and Compression Ignition Engines

Fuel Systems Standards Committee
  • Ground Vehicle Standard
  • J285_201904
  • Current
Published 2019-04-29 by SAE International in United States
This SAE Recommended Practice provides standard dimensions for liquid fuel dispenser nozzle spouts and a system for differentiating between nozzles 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 These definitions are no longer valid.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 Measure Permeation of Elastomeric Hose or Tube by Weight Loss

Fuel Systems Standards Committee
  • Ground Vehicle Standard
  • J2663_201904
  • Current
Published 2019-04-01 by SAE International in United States
This test method is intended for measuring fuel permeation at elevated temperature through low permeating hose or tubing samples of elastomeric or composite construction. The expected accuracy of the method is about ±10% of the sample permeation rate. Hose permeation testing can be done two ways: Method A – Plug and Fill or Method B – using a fuel reservoir. Method A involves plugging one end of the hose, filling the sample to about 90% full with test fuel, plugging the other end, and then exposing the plugged sample to a desired test temperature, with the weight loss measured over time. Method B involves plugging one end of a hose, and then connecting the other end to a fuel reservoir. The hose sample and reservoir are then exposed to a desired test temperature with the weight loss measured over time. This procedure presents a recommended plug design that permits inserting the plugs prior to adding the test fluid. One of the plugs has a small fill hole with a gasketing system that insures low permeation.…

Optimized Fuel Tank Sender Closure

Fuel Systems Standards Committee
  • Ground Vehicle Standard
  • J2587_201903
  • Current
Published 2019-03-08 by SAE International in United States
This practice describes recommended performance requirements of fuel tank closures used in conjunction with fuel level senders and fuel delivery systems. It provides guidelines that assure interchangeability and compatibility between fuel tanks and fuel pump/sender closure systems without specifying a specific closure system design. These systems may be used in rigid fuel tank systems made of plastic or metal. Complete details of specific designs shall be established by mutual agreement between customer and supplier. The dimensions and performance requirements are selected to optimize a The closure system, durability and reliability with respect to — Vehicle SHED measurements — Fuel system / crash integrity — LEV – II useful life b Assembly and service ease and reliability c Packaging of fuel tanks and their sending units d Interchangeability of sender closures between various fuel tank designs

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

Fuel Systems Standards Committee
  • Ground Vehicle Standard
  • J2973_201812
  • Current
Published 2018-12-19 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.

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

Fuel Systems Standards Committee
  • Ground Vehicle Standard
  • J2665_201812
  • Current
Published 2018-12-12 by SAE International in United States
This test standard covers the procedure for measuring the permeation of fuel or fuel surrogates through test samples of elastomeric, 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. Standard permeation test temperatures are 40 °C and 60 °C. Standard test fluids are Fuel C, Fuel CE10 and Fuel CM15. Other fluids, such as Fuel CMTBE15, and other volatile liquids may be tested according to this procedure as desired (SAE J1681). The method is not applicable for measuring permeation of higher boiling materials that will not completely evaporate from the exterior surface of the sample at the test temperature.

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. 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.

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

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.
