The following subjects reflect the automotive environment and are based on good engineering practices and past ("lessons learned") experiences. Since it is impossible to be all inclusive and cover every aspect of quality and reliability, this document should be used as a basis for preparation of a more comprehensive and detailed checklist that reflects the accumulated "lessons learned" at a particular Company. It is not the intent of this document to give a lot of detail, only to point out the type of subjects that need to be investigated and acted upon.

ARP6225
This document is for establishing tire removal criteria of on-wing civil aircraft tires only. This document is primarily intended for use with commercial aircraft but may be used on other categories of civil aircraft as applicable. The criteria are harmonized with the Care and Service Manuals of the tire manufacturers for both radial and bias tires.

Connected vehicles bring many benefits, helping both drivers and traffic managers. However, it can be difficult for traffic managers to analyze and use the enormous amounts of data collected when every vehicle constantly transmits speed, direction, and other data points. That’s prompting many groups to see how big data schemes can be adapted for the transportation industry.

J1939DA_201411
The J1939 Digital Annex The J1939 Digital Annex, introduced in August 2013, offers key J1939 technical data in an Electronic Spreadsheet that can be easily searched, sorted, and adapted to other formats. J1939DA contains all of the SPNs (parameters), PGNs (messages), and other J1939 data previously published in the SAE J1939 top level document. J1939DA also contains all of the SLOTs, Manufacturer ID Codes, NAME Functions, and Preferred Addresses previously published in the SAE J1939 top level and the J1939-71 document. J1939DA contains the complete technical details for all of the SPNs and PGNs previously published in the SAE J1939-71 document. For all other SPNs and PGNs which are published in a document other than SAE J1939-71, J1939DA lists only basic details along with a reference to the document that contains the complete technical details. J1939DA replaces, and expands upon, the 1939 Companion Spreadsheet (CS1939), which was last published through November 2012.

Abstract The spray development of ethanol, gasoline and iso-octane has been studied in an optically accessible, spark-ignition direct-injection (SIDI) engine. The focus is on how fuel properties impact temporal and spatial evolution of sprays at realistic ambient conditions. Two optical facilities were used: (1) a constant-flow spray chamber simulating cold-start conditions and (2) a single-cylinder SIDI engine running at normal, warmed-up operating conditions. In these optical facilities, high-speed Mie-scattering imaging is performed to measure penetrations of spray plumes at various injection pressures of 4, 7, 11 and 15 MPa. The results show that the effect of fuel type on the tip penetration length of the sprays depends on the injection conditions and the level of fuel jet atomisation and droplet breakup.

AS22759C
AS22759 specification covers fluoropolymer-insulated single conductor electrical wires made with tin-coated, silver-coated, or nickel-coated conductors of copper or copper alloy as specified in the applicable detail specification. The fluoropolymer insulation may be polytetrafluoroethylene (PTFE), fluorinated ethylene propylene (FEP), polyvinylidene fluoride (PVF2), ethylene-tetrafluoroethylene copolymer (ETFE), or other Fluoropolymer resin. The fluoropolymer may be used alone or in combination with other insulation materials. These abbreviations shall be used herein. When a wire is referenced herein, it means an insulated conductor (see 7.7).

J3021_201410
This SAE RP provides a set of test methods and practices for the characterization of the properties of Li-battery cathode active material. It is not within the scope of this document to establish criteria for the test results, as these are usually established between the vendor and customer. It is not within the scope of this document to examine the rheological properties of the cathode material in slurry since such properties are influenced by the conductive additive and the solid loading, which are determined through discussion between the manufacturer and user. It is not within the scope of this document to examine the electrochemical properties of cathode materials since these are influenced by electrode design. The committee considers that it is impossible to establish an electrode design that would be appropriate for all cathode active materials.
