Thermoset Elastomer Specification System

2009-09-10
HISTORICAL
J2884_200909
This document provides a method/ procedure for specifying the properties of vulcanized elastomeric materials (natural rubber or synthetic rubbers, alone or in combination) that are intended for, but not limited to, use in rubber products for automotive applications. This document covers materials that do not contain any re-use; recycled; or regrind materials unless otherwise agreed to by manufacturer and end user. The use of such materials, including maximum % must be specified using a “Z” suffix. This classification system covers thermoset High Consistency Elastomers (HCE’s) only. Thermoplastic Elastomer (TPE) materials are classified using SAE J2558. Silicone Formed In Place Gasket (FIPG) systems such as Room Temperature Vulcanized (RTV) Silicones, and Liquid Silicone Rubber (LSR) systems are classified using ASTM F2468.

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

2015-04-30
CURRENT
J2883_201504
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.

Vehicle Sound Measurement at Low Speeds

2009-01-16
WIP
J2889
The Vehicle Sound for Pedestrians Subcommittee of the SAE Safety and Human Factors Committee is developing a test procedure to determine the sound output of electric and hybrid-electric powertrain vehicles at certain low-speed conditions. Establishing a consistent method of measuring the sound output of these vehicles will facilitate further study into the need for additional measures to alert pedestrians to the presence of these vehicles in traffic. This test procedure could also become industry practice should it later be deemed necessary to record the sound output of certain vehicles in low speed traffic conditions where vehicles, pedestrians and other road users are co-mingled.

Guidelines for Speech Input and Audible Output in a Driver Vehicle Interface

2015-06-04
CURRENT
J2988_201506
The scope of this document is a technology-neutral approach to speech input and audible output system guidelines applicable for OEM and aftermarket systems in light vehicles. These may be stand-alone interfaces or the speech aspects of multi-modal interfaces. This document does not apply to speech input and audible output systems used to interact with automation or automated driving systems in vehicles that are equipped with such systems while they are in use (ref. J3016:JAN2014).

CURRENT
J2762_201703
This Standard provides an overview of results and requirements needed to remove refrigerant from a mobile air conditioning system for determining refrigerant emissions (leakage). This reclaim procedure for use on fleet vehicles in a field service environment should produce an accuracy and repeatability sufficient to determine refrigerant loss within 2 g.

HISTORICAL
J2760_200605
SAE J2579 is being developed by the SAE Fuel Cell Vehicle (FCV) Safety Working Group (SWG) to provide recommended practices for Fuel Systems in Fuel Cell and Other Hydrogen Vehicles. As part of this work, definitions for pressurized systems and containers were developed. The purpose of this TIR is to desiminate these definitions prior to the release of SAE J2579 such that other technical groups are aware of the information.

HISTORICAL
J2792_200811
This document proposes methods for the testing and evaluation of aluminum wheel and wheel trim surface finishes for compatibility with various types of tire, wheel and car wash cleaning materials, and other chemicals that might come into contact with these automotive components. It is recognized that each end user of this methodology might seek answers to questions that are unique to his business or situation. Therefore, the procedure is written in a generic sequence that could be strictly followed, repeated, or modified in order to provide the user with the best results. Example decision tree are provided to help the user select a sequence of exposure steps that would best suit his needs, (reference Figures 1, 2). This procedure should not be utilized if the intent is to evaluate the compatibility of wheel finishes to any flammable products, because those chemistries would require special laboratory safety and handling precautions.
