J2792_201509
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.

J2675
This SAE Recommended Practice describes a test method for determination of heavy truck tire force and moment properties under combined cornering and braking conditions. The properties are acquired as functions of slip angle, normal force, and slip ratio. Slip angle and normal force are changed incrementally using a sequence specified in this document. At each increment, the slip ratio is continually changed by application of a braking torque ramp. The data are suitable for use in vehicle dynamics modeling, comparative evaluations for research and development purposes, and manufacturing quality control.

This SAE Recommended Practice describes a test method for determination of heavy truck (Class VI, VII, and VIII) tire force and moment properties under free-rolling cornering conditions. The steady-state properties are acquired as functions of slip angle and normal force, which are changed incrementally using a sequence specified in this document. The data are suitable for use in vehicle dynamics modeling, comparative evaluations for research and development purposes, and manufacturing quality control. This document addresses two principal topics; a) the description of a hypothetical “Ideal Machine,” and b) a standard directly applicable to testing practices currently common to the industry. The references to the “Ideal Machine” are meant to provide a roadmap for the testing machine manufacturer, providing direction and goals for the next generation of testing capabilities.

J2050_201509
This SAE Standard covers two types of hose fabricated from textile reinforcement and synthetic rubber, assembled with end fittings for use in high-temperature automotive power steering applications as flexible connections within the temperature range of −40 to +150 °C (−40 to +302 °F) maximum and 10.3 MPa (1500 psi) maximum working pressure. These hoses are intended for use in applications where reduction in amplitude of pump pressure pulsation is required. Class A hose has a nominal OD of 19.84 mm (0.781 in). Class B hose is a lightweight hose with a nominal OD of 17.91 mm (0.705 in). This specification defines the minimum performance levels of a flexible connector in the hydraulic steering system to convey power steering fluid from the steering pump to the steering gear.

J2654_201508
Hardness measurements are used as a quality control check of the consistency of formulation and processing of brake linings. This hardness method is nondestructive. NOTE—This method is not a measure of friction level. The hardness and the range of hardness are characteristic of each formulation; therefore, the acceptable values and ranges must be established for each formulation and may be affected by processing. NOTE—The hardness of sintered powder metal lining is usually determined with Rockwell superficial hardness equipment. (See ASTM B 347)

This program allows wheel manufacturers to register their product compliant to SAE J3010. The following items precede display of “SAE J3010” on any particular wheel design: Manufacturer registration All manufactures with the objective to pursue registration, shall complete the registration as an individual manufacturer via the registrar’s website http://wheeldb.registrar.domain. The registration includes company contact information, wheels produced, and company identification marks.

The SAE Recommended Practice specifies a standardize method and test procedure to measure low pressure differential (< 1bar) brake component brake fluid flow performance. The standard can be utilized for flow measurements across hydraulic brake components such as master cylinders, apply system to chassis controls piping, or other sources of flow restriction in the low pressure side of the hydraulic brake system. It covers materials, manufacturing processes, and general properties required to meet the wide range of service encountered in automotive application. This specification covers only low pressure differential fluid flow and does not include measurement recommended practice for High Pressure differential (> 1 bar) flows.

This SAE Recommended Practice establishes a method of testing the structural integrity of the brake system of all new trucks, buses, and combination vehicles designed for roadway use and falling in the following classifications: Truck and Bus—Over 4500 kg (10 000 lb) GVWR Combination vehicle—Towing vehicle over 4500 kg (10 000 lb) GVWR The test consists of two distinct tests: a Structural Endurance Test followed by a Structural Ultimate Strength Test. NOTE—These two tests originated from separate procedures, and were combined in this Recommended Practice. Each test can be considered to be an independent evaluation of the service brake’s structure. Based on time available, cost limitations, and the desired evaluation and historical data available, either of these tests could be considered as a complete evaluation of the brake’s structure.

J2634_201503
This SAE practice is intended for the sample preparation of test pieces for automotive wheels and wheel trim. The practice provides a consistent scribing method for use on test panels and or component parts with substrate chemical pretreatment and coating systems. Test specimens can then be subjected to various corrosion tests in order to evaluate performance without significant variations of the degree of exposure of the substrate. The scribing is used to create a break in the coating/finishing as can occur in the field through gravel and other damaging conditions. NOTE— Significant variability is attributed to surface contour, coating hardness/softness, operator reproducibility, and the scribing tool and it’s condition.
