Standard Rainflow File Format

2002-04-30
HISTORICAL
J2623_200204
This SAE Standard provides a definition of a rainflow file format. This type of simple text file would contain all relevant information about the rainflow cycle content of a time history. Included information are Comments, Signal Range, Signal Mean, Number of Cycles, Signal Maximum, Signal Minimum. Rainflow cycle counting has become the most accepted procedure for identifying material fatigue relevant cycles in complex variable amplitude load time histories. The cycle counting methods account for the effects of material plasticity and material memory of prior deformation, and the resulting compressed history information is used by durability analysts to estimate the effects of a given service or test history.

HISTORICAL
J425_199103
The purpose of this SAE Information Report is to provide general information relative to the nature and use of eddy current techniques for nondestructive testing. The document is not intended to provide detailed technical information but to serve as an introduction to the principles and capabilities of eddy current testing, and as a guide to more extensive references listed in Section 2.

Refrigerant 12 Automotive Air-Conditioning Hose

2015-04-21
CURRENT
J51_201504
This SAE Standard covers reinforced hose, or hose assemblies, intended for conducting liquid and gaseous dichlorodifluoromethane (refrigerant 12) in automotive air-conditioning systems. The hose shall be designed to minimize permeation of refrigerant 12 and contamination of the system and to be serviceable over a temperature range of −30 to 120 °C (−22 to 248 °F). Specific construction details are to be agreed upon between user and supplier.1 NOTE—R12 refrigerant has been placed on a banned substance list due to its ozone depletion characteristics. SAE J51 specification will be phased out as new automotive A/C systems are using R134a. SAE J2064 is the Standard for refrigerant 134a hose. For refrigerant 134a use, refer to SAE J2064.

The Electric and Hybrid Electric Car

2001-11-01
This book examines trends in electric car development from a global perspective, with many examples drawing from the author's own experiences in the American and European automotive industries. Beginning with the scientific discoveries that made electric vehicle technology possible at the outset of the 20th century, author Michael H. Westbrook provides a thorough discussion of the technology's early history. Though initially overtaken by the unstoppable rise of the internal combustion engine, interest in electric vehicles began to reappear in the 1960s due to their low-emissions potential. But it was not until the passage of a California law in 1990 mandating the sale of zero-emissions vehicles (ZEVs) that major automakers began serious development of the technology.

Fuel Cell Systems Explained, Second Edition

2003-05-01
Fuel cell technology is developing at a rapid pace, thanks to the increasing awareness of the need for pollution-free power sources. Moreover, new developments in catalysts and improved reliability have made fuel cells viable candidates in a road range of applications, from small power stations, to cars, to laptop computers and mobile phones. Building on the success of the first edition, Fuel Cell Systems Explained presents a balanced introduction to this growing area. "In summary, an altogether satisfying book that puts within its covers the academic tools necessary for explaining fuel cell systems on a multidisciplinary basis." - Power Engineering Journal "An excellent book...well written and produced."- Journal of Power and Energy

Crane Hoist Line Speed and Power Test Procedure

2017-06-07
CURRENT
J820_201706
This document applies primarily to mobile cranes that lift loads by means of a drum and hoist line mechanism. It can be used to determine the hoist line speed and power of other hoist line mechanisms, if the load can be held constant and hoist line travel distance is sufficient for the accuracy of the line speed measurements prescribed. This recommended practice applies to all mechanical, hydraulic, and electric powered hoist mechanisms.
