Low Speed Continuous Slip SAE No. 2 µPVT Procedure

2018-01-30
CURRENT
J2964_201801
This SAE document is intended as the definition of a standard test, which may be subject to frequent change to keep pace with experience and technical advances. This should be kept in mind when considering its use. The SAE No. 2 friction test is used to evaluate the friction characteristics of automatic transmission plate clutches with automotive transmission fluid combinations. The specific purpose of this document is to define a µPVT test for the evaluation of the variation of wet friction system low speed slip characteristics as a function of speed, temperature, and pressure. This procedure is intended as a suggested method for both suppliers and end users. The only variables selected by the supplier or user of the friction system are: • Friction material • Fluid • Reaction plates • Oil flow (optional) These four variables must be clearly identified when reporting the results of this test.

Fuel Consumption Test Procedure - Type II

2018-01-30
WIP
J1321
This document describes a rigorous-engineering fuel-consumption test procedure that utilizes industry accepted data collection and statistical analysis methods to determine the change in fuel consumption for trucks and buses with GVWR of more than 10,000 pounds. The test procedure may be conducted on a test track or on a public road under controlled conditions and supported by extensive data collection and data analysis constraints. The on-road test procedure is offered as a lower cost alternative to on-track testing but the user is cautioned that on-road test may result in lower resolution (or precision) data due to a lack of control over the test environment. Test results that do not rigorously follow the method described herein are not intended for public use and dissemination and shall not be represented as a J1321-Type II test result.

Carbon Steel Tubing for General Use - Understanding Nondestructive Testing for Carbon Steel Tubing

2018-01-29
WIP
J2592
This SAE information report provides a means to understand the various methods of evaluating the integrity of steel tubing without the need of destroying the tubing. This report describes eddy current testing, flux leakage testing, ultrasonic testing, and magnetic particle testing of steel tubing. The primary purpose of these methods of testing steel tubing is to look for flaws in the tubing, such as discontinuities, seams, cracks, holes, voids and other imperfections characteristic to the specific construction of the tubing.

Aircraft Exhaust Nonvolatile Particle Matter Measurement Method Development

2018-01-29
WIP
AIR6037A
This report provides current practice measurement methods for quantifying non-volatile particle matter at the exit plane of aircraft gas turbine engines. This document contains detailed information for many instruments and techniques, described in AIR 5892, that have been applied in aircraft engine field tests since AIR 5892 was first issued in April 2003. There are four sections, identified as Technical Appendices (TA), presenting measurement techniques, sampling, and quantification of non-volatile particles. The sections are written in the format of an Aerospace Recommended Practice (ARP) and intended to progress to recommended practices upon overcoming existing technical challenges.

AMSA22771D
The initial SAE publication of this document was taken directly from U.S. Military Standard MIL-A-22771D. This SAE Standard may retain the same part numbers established by the original military document. Any requirements associated with Qualified Products Lists (QPL) may continue to be mandatory for DoD contracts. Requirements relating to QPLs have not been adopted by the SAE for this standard and are not part of this SAE document.

Graphic Symbols for Aircraft Hydraulic and Pneumatic Systems

2018-01-25
WIP
AS1290C
This Aerospace Standard (AS) presents a system of graphic symbols intended primarily for usage in hydraulic and pneumatic system schematic diagrams for all types of aircraft. It is also considered suitable for marine vehicles and other applications and for ancillary documents where schematics are required. Individual graphic symbols shown herein are also considered suitable for use in conjunction with other types of symbols. This AS is intended to promote industry-wide acceptance and understanding of uniform standards and employs, where possible, symbols which are internationally recognized.

Procedure for the Calculation of Aircraft Emissions

2018-01-25
WIP
AIR5715A
This AIR describes procedures for calculating emissions resulting from the main engines of commercial jet and turboprop aircraft through all modes of operation for all segments of a flight. Piston engine aircraft emissions are not included in this AIR. Some information about piston engine aircraft emissions can be found in FOCA 2007. The principal purpose of the procedures is to assist model developers in calculating aircraft emissions in a consistent and accurate manner that can be used to address various environmental assessments including those related to policy decisions and regulatory requirements.

Automotive Gear Lubricants for Commercial and Military Use

2018-01-25
WIP
J2360
The gear lubricants covered by this standard exceed American Petroleum Institute (API) Service Classification API GL-5 and are intended for hypoid type, automotive gear units, operating under conditions of high-speed/shock load and low-speed/high-torque. These lubricants may be appropriate for other gear applications where the position of the shafts relative to each other and the type of gear flank contact involve a large percentage of sliding contact. Such applications typically require extreme pressure (EP) additives to prevent the adhesion and subsequent tearing away of material from the loaded gear flanks. These lubricants are not appropriate for the lubrication of worm gears. Appendix A is a mandatory part of this standard. The information contained in Appendix A is intended for the demonstration of compliance with the requirements of this standard and for listing on the Qualified Products List (QPL) administered by the Lubricant Review Institute (LRI).
