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

2006-10-13
CURRENT
J2665_200610
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 Procedure to Measure Permeation of Elastomeric Hose or Tube by Weight Loss

2010-06-16
CURRENT
J2663_201006
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.

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.

Test Method to Measure Fluid Permeation of Polymeric Materials by Speciation

2012-07-30
CURRENT
J2659_201207
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.

HISTORICAL
J2027_199406
This SAE Standard covers the performance requirements for protective covers for gasoline fuel tubing. The ultimate performance of the protective cover can be highly dependant on the interaction of the fuel line tubing and protective cover. Therefore, it is recommended that specific tubing and cover combinations be tested as an assembly to qualify to this document. This document is intended to provide guidance to the engineer on the key performance parameters for protective covers for gasoline fuel tubing. This document is designed to allow selection of predetermined performance levels for these key performance parameters. The engineer may select a specification by the use of a line call-out designation, which will denote the pertinent characteristics of the cover material and/or the tube/cover assembly and their corresponding performance criteria. The engineer is not required to select every characteristic, but only those deemed important to the application.

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

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

J1747_200707
This SAE Information Report is intended to convey the test methods developed for use in testing with methanol and gasoline blends. Corrosion testing of metals has a long and varied history. In spite of the problems inherent in extrapolating results of accelerated tests on standard specimens to actual field durability, engineers have been able, to a large extent, to rely on these results in making materials selection decisions. However, these tests have generally employed aqueous media and are not strictly applicable to the use of organic chemical media. With methanol-gasoline fuel blends and their high electrical conductivity relative to gasoline, the relevance of the historical database is lost. Therefore, to allow rapid build-up of a new database, several corrosion test procedures have been reviewed and amended where appropriate.
