Safety Assurance Trailers for SAE J1939-22 C-PGs

2022-02-25

WIP

J1939-77

This document specifies the technical requirements for several different trailers that may be incorporated into J1939-22 C-PG payloads to provide safety assurance data. Proper use of these trailers is suitable for meeting applicable functional safety standards for a given industry. This document provides enough details for trailers that another document (likely SAE J1939-22) can incorporate these details into specific trailer formats. Accordingly, this document does not define the Type of Service (TOS) or Trailer Format (TF) values to use for these trailers, nor does it define the position of these trailers relative to other trailers that provide security assurance data.

Performance Requirements for Nonmetallic Air Brake System Tubing

2014-08-26

WIP

J2547

This SAE Standard covers the minimum requirements for nonmetallic tubing as manufactured for use in air brake systems which tubing is different from that described in SAE J844. It is not intended to cover tubing for any portion of the system which operates continuously below - 40 degrees C or above +93 degrees C, above a maximum working gage pressure of 1.0 MPa, or in an area subject to attack by battery acid. This tubing is intended for use in the brake system for connections, which maintain a basically fixed relationship between components during vehicle operation. Coiled tube assemblies required for those installations where flexing occurs are covered by this document, SAE J1131 and SAE J2494-3, to the extent of setting minimum requirements on the essentially straight tube and tube fitting connections which are used in the construction of such assemblies.

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.

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.
