Standard Formats for Presenting Acoustical Data

2011-05-01
HISTORICAL
J2629_201105
SAE developed this document at the request of automobile manufacturers to help compare products from multiple suppliers using standard data presentation formats. This document includes several preferred formats for presenting acoustical data on materials, components, systems, or vehicles. These formats cover the range of acoustical tests commonly conducted in the automotive industry. These tests follow SAE and ASTM test practices as well as vehicle specific test methods. For each test, the details of samples and test conditions are entered into an electronic template together with the acoustical results data. These data are then linked to standard graphical display(s) for each test. All manufacturers and suppliers in this industry are encouraged to present data and results in these formats. Although this practice was developed specifically for use in the automotive industry, the formats are useable in otherindustries and applications as well.

Defining Hydraulic Oil Compatibility With Hydraulic Hose Elastomers

2006-03-27
HISTORICAL
J2631_200603
This SAE Information Report is intended to provide the hydraulic oil manufacturer and hydraulic equipment manufacturer with information that can be used predicting the relative impact that non petroleum based hydraulic oils may have on the hose elastomers in the existing system. This document contains the information necessary to perform the tests using standard elastomer formulations, representative of material used in hydraulic hose. The test methods used are defined within ASTM D471, standard test method for Rubber Property-Effect of Liquids. The physical properties measured, are volume swell, tensile strength, percent elongation, shore A hardness and load at 100% elongation. The properties were measured, after immersion, at 72 hours, 168 hours, 336 hours, 504 hours, 672 hours, 840 hours, and 1008 hours and the percent calculated as change from the unaged properties. The detail of the testing process is described in the following report.

Draft Comprehensive Lining Evaluation--Vehicle

2003-05-28
HISTORICAL
J2624_200305
There is currently no requirement in place for aftermarket brake lining performance. NHTSA has indicated that the automotive aftermarket should take a proactive approach to come up with a standard test definition for lining evaluation. Many aftermarket manufacturers use dynamometer testing to evaluate lining performance, but there is currently not a common recognized method for on-vehicle lining screening. This procedure was created to provide a quick, on-vehicle test method for lining performance evaluation. This procedure is intended for use in passenger cars; multi purpose vehicles and light trucks with a gross vehicle weight less than 4535 kg(10 000 lb). Purpose This Recommended Practice is intended to provide the automotive aftermarket brake lining manufacturer with an on-vehicle test procedure for comparison of brake lining performance with Original Equipment or a competitor's performance. Care should be taken to maintain consistency between tests that are being compared.

Standard Rainflow File Format

2002-04-30
CURRENT
J2623_200204
This SAE Standard provides a definition of a rainflow file format. This type of simple text file would contain all relevant information about the rainflow cycle content of a time history. Included information are Comments, Signal Range, Signal Mean, Number of Cycles, Signal Maximum, Signal Minimum. Rainflow cycle counting has become the most accepted procedure for identifying material fatigue relevant cycles in complex variable amplitude load time histories. The cycle counting methods account for the effects of material plasticity and material memory of prior deformation, and the resulting compressed history information is used by durability analysts to estimate the effects of a given service or test history.
