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

2018-12-19
CURRENT
J2973_201812
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.

Quick Connect Coupling Specification for Liquid Fuel and Vapor/Emissions Systems

2009-08-13
CURRENT
J2044_200908
This SAE Recommended Practice defines the minimum functional requirements for quick connect couplings used for supply, return, and vapor/emission fuel system connections. This document also defines standard male tube end form dimensions, so as to guarantee interchangeability between all connector designs of the same male tube end form size. This document applies to automotive and light truck applications under the following conditions: a Gasoline and diesel fuel delivery systems or their vapor venting or evaporative emission control systems. b Operating pressure up to 500 kPa, 5 bar, (72 psig). c Operating vacuum down to −50 kPa, −0.5 bar (−7.2 psi). d Operating temperatures from −40 °C (−40 °F) to 115 °C (239 °F). Quick connect couplings function by joining the connector to a mating tube end form, then pulling back to assure a complete connection. The requirements stated in this document apply to new connectors in assembly operations unless otherwise indicated.

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

2012-11-01
CURRENT
J398_201211
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.

Requirements for Built-In Service Port for On Board Diagnostics

2008-08-11
CURRENT
J2744_200808
This document presents the requirements for a built-in service port to be used in vehicles intended to comply with Enhanced Evaporative Emissions 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 evacuates them out of, the system. This access may be used for the following evaluations: • Evaporative System Certifications Canister Loading and Purging • 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

Standard for Protective Covers for Gasoline Fuel Line Tubing

2013-05-28
CURRENT
J2027_201305
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.

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

2019-08-26
CURRENT
J1737_201908
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.
