Abrasion Resistance Testing - Vehicle Exterior Graphics and Pin Striping

2021-01-07

CURRENT

J1847_202101

This SAE Recommended Practice applies to the abrasion resistance testing of decorative tapes, graphics, and pin striping. It may also have relevance to certain vehicle labels and plastic wood grain film. The resistance to abrasive damage is judged qualitatively by its effect on the legibility, pattern, and color of the graphic marking. This recommended practice is intended as a guide toward standard practice but may be subject to frequent change to keep pace with experience and technical advances. This should be kept in mind when considering the use of this recommended practice.

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.

Technical Report on Low Cycle Fatigue Properties Ferrous and Non-Ferrous Materials

2018-08-24

CURRENT

J1099_201808

Information that provides design guidance in avoiding fatigue failures is outlined in this SAE Information Report. Of necessity, this report is brief, but it does provide a basis for approaching complex fatigue problems. Information presented here can be used in preliminary design estimates of fatigue life, the selection of materials and the analysis of service load and/or strain data. The data presented are for the “low cycle” or strain-controlled methods for predicting fatigue behavior. Note that these methods may not be appropriate for materials with internal defects, such as cast irons, which exhibit different tension and compression stress-strain behavior.

CURRENT

J1121_201608

The following recommended practice has been developed to assist engineers and designers in the preparation of specifications for the major types of helical compression and extension springs. It is restricted to a concise presentation of items which will promote an adequate understanding between spring manufacturer and spring user of the major practical requirements in the finished spring. Closer tolerances are obtainable where greater accuracy is required and the increased cost is justified. For the basic concepts underlying the spring design and for many of the details, see the SAE Information Report MANUAL ON DESIGN AND APPLICATION OF HELICAL AND SPIRAL SPRINGS, SAE HS 795, which is available from SAE Headquarters in Warrendale, PA 15096. A uniform method for specifying design information is shown in the TYPICAL DESIGN CHECK LISTS FOR HELICAL SPRINGS, SAE J1122.

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.

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.

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.
