Standard Rainflow File Format

2002-04-30
HISTORICAL
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.

Ball Joints

2012-10-15
CURRENT
J490_201210
This SAE Standard covers the general and dimensional data for various types of ball joints with inch threads commonly used on control linkages in automotive, marine, and construction and industrial equipment applications. Inasmuch as the load carrying and wear capabilities of ball joints vary considerably with their design and fabrication, it is suggested that the manufacturers be consulted in regard to these features and for recommendations relating to application of the different types and styles available. The inclusion of dimensional data in this standard is not intended to imply that all the products described are stock production sizes. Consumers are requested to consult with manufacturers concerning availability of stock production parts.

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.

Decorative Anodizing Specification for Automotive Applications

2013-03-28
CURRENT
J1974_201303
This SAE Recommended Practice is aimed at ensuring high-quality products of anodized aluminum automotive components in terms of durability and appearance. Decorative sulfuric acid anodizing has been well developed over the last several decades in the aluminum industry. Exterior and interior performance demonstrated that parts processed to this document meet long-term durability requirements. Since the treatment of processing variables is outside the scope of this document, it is important for applicators of this coating to develop an intimate knowledge of their process, and control all parameters that affect the quality of the end product. The use of techniques such as statistical process control (SPC), capability studies, design of experiments, process optimization, etc., are critical to produce material of consistently high quality.

Electroplating of Nickel and Chromium on Metal Parts-Automotive Ornamentation and Hardware

1985-02-01
HISTORICAL
J207_198502
This standard covers requirements for several types and grades of electrodeposited nickel/chromium coatings on ferrous or copper alloy basis metals and copper/nickel/chromium on zinc or aluminum alloys for the finishing and corrosion protection of decorative ornamentation and hardware of motor vehicles and marine controls and fittings. Four grades of coatings are provided to correlate with the service conditions under which each is expected to provide satisfactory performance, namely: very severe, severe, moderate, and mild. Definitions and typical examples of these service conditions are provided in Appendix A. Information contained in this document generally conforms to the information contained in ASTM B 456, Specification for Electrodeposited Coatings of Nickel plus Chromium.

Laboratory Corrosion/Fatigue Testing of Vehicle Suspension Coil Springs

2007-06-15
HISTORICAL
J2800_200706
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.

Multi-Dimensional Thermal Properties of Insulated Heat Shield Material Systems

2018-08-24
CURRENT
J2609_201808
This test method measures the system material properties of an insulated formed heat shield under in-vehicle conditions. While the material properties of the individual components can often be determined via existing test methods, the system properties of the entire composite is typically much harder to ascertain (especially for multi-layer shields). System material properties include thermal conductivity in the lateral or in-plane (x) direction, thermal conductivity through the thickness or perpendicular (y), surface emissivity on the top and bottom sides of the shield and specific heat of the shield material.
