Standard Rainflow File Format

2018-08-24
CURRENT
J2623_201808
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.

Strain-Life Fatigue Data File Format

2018-08-24
CURRENT
J2649_201808
SAE data file format for exchanging controlled periodic overload data. The object of this SAE Standard is to provide a simple, common methodology for exchanging the data from periodic overload fatigue tests. These tests consist of a single large fatigue cycle followed by a larger number of smaller cycles. The overloads are fully reversed fatigue cycles while the smaller cycles share a common mean and amplitude.

Helical Springs: Specification Check Lists

2016-08-02
CURRENT
J1122_201608
The following SAE Recommended Practice furnishes sample forms for helical compression, extension and torsion springs to provide a uniform method for specifying design information. It is not necessary to fill in all the data, but sufficient information must be supplied to fully describe the part and to satisfy the requirements of its application. For detailed information, see “Design and Application of Helical and Spiral Springs - SAE HS 795”, also “Helical Compression and Extension Spring Terminology - SAE J1121”. Both of these documents use SI (metric) Units in accordance with the provisions of SAE TSB 003, as does SAE J1122. Here, however, the U.S. Customary Units (in, lb, psi) have been added in parentheses after each SI Unit for the convenience of the user who must furnish specifications on a project where all requirements are listed in non-metric terms.

Body Corrosion - A Comprehensive Introduction

2016-04-05
CURRENT
J1617_201604
The mechanism of automotive body corrosion is scientific, based on established laws of chemistry and physics. Yet there are many opinions related to the cause of body corrosion, not always based on scientific axioms. The purpose of this SAE Information Report is to present a basic understanding of the types of body corrosion, the factors that contribute to body corrosion, the testing procedures, evaluation of corrosion performance, and glossary of related terms.

Guidelines for Laboratory Cyclic Corrosion Test Procedures for Painted Automotive Parts

2016-04-05
CURRENT
J1563_201604
These guidelines are intended for those engineers and scientists who evaluate the corrosion performance of painted automotive parts in laboratory cyclic tests. The guidelines are intended to help ensure that the results of the tests can be used to reach conclusions concerning the variables under study without being confounded by the test procedure itself. The guidelines also serve as a means to assist users of this type of test in obtaining good inter-laboratory agreement of results.

J1950_201604
The facilities used by domestic automotive manufacturers to provide accelerated corrosion aging of complete vehicles are described in general. The types of vehicles tested, general test methodology, and techniques used to determine test-to-field correlation are discussed. The different procedures used throughout the industry produce different results on various vehicle coatings, components, and systems. The key to successful interpretation of test results is a thorough understanding of the corrosion mechanisms involved and the effects of test limitations on these mechanisms.

Laboratory Cyclic Corrosion Test

CURRENT
J2334_201604
The SAE J2334 lab test procedure should be used when determining corrosion performance for a particular coating system, substrate, process, or design. Since it is a field-correlated test, it can be used as a validation tool as well as a development tool. If corrosion mechanisms other than cosmetic or general corrosion are to be examined using this test, field correlation must be established.

Laboratory Corrosion/Fatigue Testing of Vehicle Suspension Coil Springs

2016-04-01
CURRENT
J2800_201604
This lab test procedure should be used when evaluating the combined corrosion and fatigue performance for a particular coating system, substrate, process and design. The test is intended to provide an A to B comparison of a proposed coil spring design versus an existing field validated coil spring when subjected to the combined effects of corrosion and fatigue. The corrosion mechanisms covered by this test include general, cosmetic and pitting corrosion. Fatigue testing covers the maximum design stress and/or stress range of the coil spring design (typically defined as excursion from jounce to rebound positions in a vehicle). The effects of gravel and heat are simulated by pre-conditioning the springs prior to fatigue testing. Time dependant corrosion mechanisms such as stress corrosion cracking are not addressed with this test.

Parallel Side Splines for Soft Broached Holes in Fittings

2014-06-05
CURRENT
J499_201406
This Information Report along with SAE J500 and J501 is generally understood to be technically obsolete for the design of new applications. However, it is listed for those existing applications where it may be required. For the design of new applications, consult ANSI B92.1-1970—Involute Splines and Inspections Standard. [The dimensions, given in inches, apply only to soft broached holes. The shaft dimensions depend upon the shape and material of the parts, their heat treatment, and methods of machining to give the required fit. The method and amount of "breaking" sharp corners and edges also depend upon the conditions and requirements of each application. The formula for theoretical torque capacity (pressure on sides of spline) in inch-pounds per inch of bearing length (L) and at 1000 psi pressure is: The tolerances allowed are for good construction and may be readily maintained by usual broaching methods.
