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 Measure the Fuel Permeability of Materials by the Cup Weight Loss Method

2018-11-07
WIP
J2665
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 filing 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 60C. Standard test fluids are Fuel C, Fuel CE10 and Fuel CM15. Other fluids, such as Fuel CMTBE15, and other volatile liquids may be tested accordingly 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.

WIP
ARP5029B
This SAE Aerospace Recommended Practice (ARP) provides the user with standardized guidelines for the measurement of effective intensity of strobe anticollision lights for aircraft in the laboratory, in maintenance facilities, and in the field. A common source of traceability for calibration of the measurement systems, compensation for known causes of variation in light output, and recommendations which minimize sources of errors and uncertainties are included in this document. Estimates of uncertainty and error sources for each class of measurement are discussed.

Standard - Optical System HUD for Automotive

2018-11-06
CURRENT
J1757-2_201811
This SAE Standard provides measurement methods to determine HUD optical performance in typical automotive ambient lighting conditions. It covers indoor measurements with simulated outdoor lighting for the measurement of HUD virtual images. HUD types addressed by this standard includes w-HUD (windshield HUD) and c-HUD (combiner HUD) with references to Augmented Reality (AR) HUD as needed. It is not the scope of this document to set threshold values for automotive compliance; however, some recommended values are presented for reference.

J1942/1
The following list consists of hose data provided as of December 2017, and is for convenience in determining acceptability of nonmetallic flexible hose assemblies intended for usage under 46 CFR 56.60-25. Where the maximum allowable working pressure (MAWP) or type of fitting is not specified, use the manufacturer's recommended MAWP or type of fitting. This list has been compiled by SAE Staff from information provided by the manufacturers whose product listings appear in this document. Manufacturers wishing to list their products in this document shall: a. Successfully test their hose to the requirements of SAE J1942, Table 1. b. Submit a letter of certification to the SAE J1942 test requirements for each specific type of hose tested (see sample table on page 4) along with the test results. All sizes should be included in the same letter which must also include all of the information necessary to make a SAE J1942-1 listing. c.

WIP
J3189
This SAE Recommended Practice applies to both Original Equipment Manufacturer (OEM) and aftermarket message-generating systems for light and heavy vehicles. The recommended practice covers both message prioritization and presentation (including simultaneous display of messages) for visual and auditory modalities. In addition, this recommended practice will consider temporal aspects of external events (e.g. merging into heavy traffic, time-to-collision) and their impact on temporal presentation and format (including multi-modal) of messages.

Test Method to Measure Fluid Permeation of Polymeric Materials By Speciation

2018-11-05
WIP
J2659
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.
