Motor Vehicle Brake Fluid Container Compatibility

2018-07-12
CURRENT
J75_201807
Motor vehicle brake fluid must conform to the requirements of SAE J1703 or J1704, not only when manufactured, but also after extended storage in any commercial packaging container. The purpose of this SAE Information Report is to generate an awareness of the major problems involved in the storage of brake fluids and, to some extent, provide means of circumventing them. It is also the purpose of this document to relate to experience and to test data accumulated and to list certain conclusions which should aid in the proper selection of containers for brake fluid.

CURRENT
AS1730E
This specification defines the requirements for a threaded rigid coupling assembly, which utilizes ferrule type machined tube end fittings, to join tubing and components in aircraft fuel, vent, and other systems. This coupling assembly is designed for use from -65 to 200 °F and at 125 psig operating pressure.

Early Acquisition and Preservation of Information in a Motor Vehicle Crash

2018-07-12
CURRENT
J1674_201807
The purpose of this SAE Recommended Practice is to offer simplified and prioritized guidelines for collecting and preserving on-scene data related to motor vehicle crashes. It is intended that these guidelines improve the effectiveness of data collection, which will assist subsequent analysis and reconstruction of a particular crash. This document is intended to guide early data collectors whose objectives include documenting information related to the crash. It may be used by law enforcement personnel, safety officials, insurance adjusters and other interested parties. This document identifies categories of scene physical features that deteriorate relatively quickly and recommends documentation task priorities. Detailed methods of collecting data are not part of this document. However, some widely used methods are described in the references in Section 2.

CURRENT
J646_201807
Figures 1 through 5 illustrate in simplified form some of the more common planetary gear arrangements in order to establish applicable terminology. Figures 6 and 7 provide additional examples that use elements of those gear arrangements. Gear ratio is the numerical ratio of input to output speed.

Laboratory Measurement of Random Incidence Sound Absorption Tests Using a Small Reverberation Room

2018-07-10
WIP
J2883
This SAE Recommended Practice describes a laboratory test procedure for measuring the random incidence sound absorption performance of a material or a part in a small size reverberation room by measuring decay rates. The absorption performance may include sound absorption coefficient of the test sample and or the amount of energy absorbed by the test sample. Materials for absorption treatments may include homogeneous materials, nonhomogeneous materials, or a combination of homogeneous, nonhomogeneous, and/or inelastic impervious materials. These materials are commonly installed in the mobility products and in the transportation systems such as ground vehicles, marine products, aircraft, and commercial industry (in industrial and consumer products) to reduce reverberant sound build-up and thus reduce the noise level in the environment by minimizing reflections off of hard surfaces.
