Tolerances, Corrosion and Heat-Resistant Steel Tubing

2018-09-25
WIP
AMS2243L
This specification covers manufacturing tolerances applicable to seamless and welded tubing of corrosion and heat-resistant steel ordered to inch dimensions. These tolerances apply to all conditions and are based on individual measurements, unless otherwise noted. Tubing may be specified by two dimensions only (OD and wall thickness, ID and wall thickness, or OD and ID).

Low Speed Enveloping Test with Perpendicular and Inclined Cleats

2018-09-25
WIP
J2731

This SAE Recommended Practice describes a test method for measuring the forces and moments generated at a spindle when a tire rolls over a rectangular obstacle, cleat, at very low speed. The cleat used in a particular test condition is configured with its crest either perpendicular, 90 degrees, to the path of the tire or optionally with its crest inclined at an angle to the path of the tire. The carriage to which the spindle is attached is rigidly constrained in position during each test condition so as to provide a good approximation to fixed loaded radius operation. The method discussed in this document provides cleat envelopment force and moment and tire angular position histories as functions of distance traveled. These histories are essentially free from variations due to tire non-uniformities. The method applies to any size tire so long as the equipment is properly scaled to conduct the measurements for the intended test tire.

Contaminants for Testing Air Brake Components and Auxiliary Pneumatic Devices—Truck and Bus

2018-09-24
WIP
J2024
This SAE Information Report establishes a minimum level of uniform recipes for contaminants which may be used when durability testing pneumatic components to obtain additional information on how a device may perform under more true to-life operating conditions. This type of contamination testing, however, is not meant to replace the type of performance testing described in SAE J1409 and SAE J1410. Durability testing in the presence of contamination, however, will yield results more reflective of actual in-service field conditions and provide an additional evaluation of pneumatic devices. While the contaminant supply rate and other test criteria of the device being tested must be set by the device manufacturer or user, the items covered in this document will be: 1.1 Formula for contaminated oil to be used as a lubricant when testing air compressors. 1.2 Formula for a contaminant to be used when testing pneumatic system components other than air compressors. 1.3 Other contaminants.

Recommended Practices (RP) for Shipping Transport and Handling of Automotive-Type Battery System - Lithium Ion

2018-09-24
WIP
J2950
This RP aids in the identification, handling, and shipping of new and used un-installed lithium ion battery systems to and from specified locations. The generic term “battery system” shall be used to identify automotive-type and sized “traction” batteries when used as intended by the vehicle and battery system original equipment manufacturers (OEMs) for ground vehicles. It is the specific intent of this RP to identify, utilize and reference existing US and International hazardous materials (dangerous goods) transportation regulations, which are the only methodologies to be used to establish transportability of new battery systems. It is also the intent of this RP to provide recommendations regarding diagnostic testing to be used by service and shipping personnel for the purpose of determining a used battery system’s transportability. In support of the service and shipping personnel, the diagnostics process seeks to use standard tools of the trade and avoid laboratory type equipment.

Automotive and Off-Highway Air Brake Reservoir Performance and Identification Requirements - Truck and Bus

2018-09-24
WIP
J10
This SAE Standard applies to all new production air brake and air accessory reservoirs used in automotive vehicles and off-road machines. This document defines an “air reservoir” as a reservoir having single or multiple compartments that is used for storage of compressed air. This document does not apply to accumulators or reservoirs for storage of gases other than compressed air.

Taxonomy and Definitions for Terms Related to Shared Mobility and Enabling Technologies

2018-09-24
CURRENT
J3163_201809
This Recommended Practice provides a taxonomy and definitions for terms related to shared mobility and enabling technologies. Included are functional definitions for shared modes (e.g., carsharing, bikesharing, ridesourcing, etc.). Public transit services and other incumbent services—such as car rentals, shuttles, taxis, paratransit, ridesharing (carpooling/vanpooling), and pedicabs—are also included in the ecosystem of shared mobility services. This Recommended Practice also provides a taxonomy of related terms and definitions (e.g., station-based roundtrip, free-floating one-way, etc.). This Recommended Practice does not provide specifications or otherwise impose requirements on shared mobility.

CURRENT
J1098_201809
This SAE Standard establishes the procedures for the application of Tonne Kilometer Per Hour (TKPH) rating values for off-the-road tires; utilizing empirical data formula, it describes the procedure for evaluating and predicting off-the-road tire TKPH requirements as determined by a work cycle analysis.
