Tire Size Differential - Articulated Wheel Loader

2019-11-20
CURRENT
J2204_201911
This SAE Standard applies to the usage of tires of the same nominal size and tread type, but with different outside diameter for articulated front-end loaders. Articulated four-wheel-drive front-end loader performance and component life can be affected by excessive differences in the tire outside circumference and/or diameter. The purpose is to provide specific guidelines for the usage of tires with different outside circumference and/or diameter on articulated front-end loaders.

Graphics-Based Service Information

2021-11-23
CURRENT
J2892_202111
This document establishes standard graphical symbols and color conventions for use in either still (static) or animated graphics used for communicating service information. This document’s purpose is to communicate conventions for using those symbols and colors to accurately and consistently communicate intended information via graphics-based documentation. These practices are intended for use in service procedures, assembly instructions, training materials, and similar applications when trying to minimize the amount of human natural language text used within the document. The still and animated graphical conventions referenced should support effective communication via paper and “traditional” electronic media. The conventions can also extend to documenting via additional electronic delivery paradigms such as augmented reality (AR).

Fuel Economy Measurement Test (Engineering Type) for Trucks and Buses

1997-12-01
CURRENT
J1376_199712
This procedure incorporates test cycles that produce relative fuel economy data relating to long haul, short haul, and local driving patterns, or any combination of these and to those components developed to improve fuel economy for these patterns. The tests conducted on a specific vehicle are to reflect that vehicle's general mode of operation. The procedure is intended to be used under controlled, warmed-up conditions on a test tract or on suitable roads. A minimum of two vehicles running simultaneously is required. Test condition recommendations are provided for undertaking this engineering test. If it is necessary to conduct a test outside of these test conditions, the purpose of the test and the variant conditions should be recorded and noted whenever the results are reported.

Dynamic Wireless Power Transfer for both Light and Heavy Duty Vehicles (SAE RP J2954/3)

2023-04-20
WIP
J2954/3
The SAE J2954 standard establishes an industry-wide specification that defines acceptable criteria for Light Duty EVs and SAE RP J2954/2 establishes the same for Heavy Duty. SAE RP SAE J2954. SAE RP J2954/3 establishes interoperability, electromagnetic compatibility, EMF, minimum performance, safety, and testing for dynamic wireless power transfer (D-WPT) of both light and heavy duty plug-in electric vehicles. The specification defines various charging levels that are based on the levels defined for SAE J1772 conductive AC charge levels as SAE J2954/1 & SAE J2954/2 with some variations. A standard for WPT based on these charge levels enables selection of a charging rate based on vehicle requirements, thus allowing for better vehicle packaging and ease of customer use. SAE J2954/3 addresses unidirectional charging, from grid to vehicle; bidirectional energy transfer may be evaluated for a future standard.
