This standard specifies a procedure for approximating the volume of materials contained in the grapple of bucket linkage operated grapples mounted to excavators. The volume ratings are based on the inside dimensions of the grapple and representative volumes extending beyond the grapple. The method employs the technique of dividing the complex shape of the material in the grapple into simple geometric forms to allow volume calculations of different grapple configurations. The rating method is intended to provide a consistent means of comparing grapple capacities. It is not intended to define actual capacities that might be observed in any specific application.

The purpose of this SAE Recommended Practice is to describe the terms yield strength and yield point. Included are definitions for both terms and recommendations for their use and application.

This document describes a rigorous engineering test procedure that utilizes industry-accepted data collection and statistical analysis methods to determine the road load and to estimate the aerodynamic drag area of trucks and buses weighing more than 10000 pounds. The test procedure may be conducted on a test track or on a public road under controlled conditions and supported by extensive data collection and data analysis constraints. The estimated aerodynamic-drag-area result represents a single-speed and single-yaw-angle condition. Test results that do not rigorously follow the method described herein shall not be represented as an SAE J2978 result.

This SAE J2971 Recommended Practice describes a standard naming convention of aerodynamic devices and technologies used to control aerodynamic forces on truck and buses weighing more than 10000 pounds (including trailers).

This SAE J2971 Recommended Practice Truck and Bus Aerodynamic Device Terminology document describes a standard naming convention of aerodynamic devices and technologies used to control aerodynamic forces on truck and buses weighing more than 10,000 pounds (including trailers).

This Recommended Practice is intended to establish a procedure to certify the trailer towing driving skill levels of professional drivers. This certification can be used by the individual driver to qualify their skills when seeking employment or other professional activity. These certification levels may also be used by test facilities or other organizations when seeking test or professional drivers of various skills. This document provides directions for obtaining certification through Probitas Authentication®1 and associated trailer towing driving skill examination requirements. This document is a supplement to SAE J3300, providing information specific to the trailer towing driving skill certification and clarifying the application of the rules set forth in SAE J3300 to the trailer towing certification. While the references, definitions, rules, and guidelines presented in SAE J3300 Sections 1 through 5 apply to the trailer towing certification, they are not repeated in this document.

This SAE Information Report establishes a consistent procedure for measuring and analyzing the natural sway response of a particular trailer when attached to a particular vehicle under specific loading and operating conditions. This test procedure applies, but is not limited to, passenger cars, vans, light/medium-duty trucks as tow vehicles, and semitrailers with a Gross Vehicle Weight Rating (GVWR) of 11 794 kg (26 000 pounds) or less. Other applications include full trailers, tow dollies, tow bars, and the like. Other articulated vehicles can utilize this test procedure as long as the test does not exceed the linear behavior of the system. This test procedure does not apply to motorcycles towing trailers.

The scope of this SAE Recommended Practice, trailer axle alignment, is to identify the dimensional limits of, and a method to, establish a perpendicular relationship between the king pin centerline and the axle centerline at its midpoint. Various types of equipment are commercially available which can be used for this measurement which provides varying degrees of accuracy, but none can be endorsed by SAE. The most fundamental methods of measurement will be described here, but other equipment is available if a greater degree of accuracy is desired.

This SAE Standard establishes a criteria for a minimum zone of protection for the operator of the machine and establishes certain structural requirements for guards on pneumatic-tired earthmoving haulage machines capable of speeds in excess of 25 km/h. Earthmoving machines covered by this document are dumpers and tractor-scrapers as identified in SAE J/ISO 6165.

This method covers electric outboards that are rated in terms of static thrust.

This method covers all electric outboards.

This method covers all electric outboards.

The lift capacity can be determined by Section 4 and/or Section 5. When the results are recorded, the test method shall be identified.

This SAE standard is intended to create standard terminology related to light and medium duty trailer applications. This includes such trailer types as utility, boat, camping, travel, and special purpose trailers which are normally towed by conventional passenger cars, light-duty commercial vehicles, light trucks, and multipurpose passenger vehicles.
