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.

SAE MANUAL ON BLAST CLEANING

1968-06-01
CURRENT
J792A_196806
Blast cleaning may be defined as a secondary manufacturing process in which a suitable stream of solid particles is propelled with sufficient velocity against a work surface to cause a cleaning or abrading action when it comes in contact with the workpiece. As indicated in the definition, blast cleaning may be employed for a variety of purposes. Ordinarily, it is considered as a method for removing sand from castings, burrs or scale from forgings, mill products, or heat treated parts; to promote machinability, and to minimize the possibility of interference in actual operation. In addition to this use, blast cleaning also produces an excellent surface for industrial coatings. All these objectives are often accomplished in the one operation.

Diesel Injection Pump Testing—Part 2: Orifice Plate Flow Measurement

2015-09-22
CURRENT
J968/2_201509
This part of SAE J968 specifies the flow measuring system, including the fixture, to be used for flow testing the single hole orifice plates used in an orifice plate type nozzle and holder assembly (described in SAE J968-1) which is intended for testing and setting diesel fuel injection pumps on test benches. The flow measuring system and fixture ensure accurate flow testing of the entire range of orifices from 0.4 to 0.8 mm diameter as specified in SAE J968-1. It is intended primarily for use by the manufacturers of single hole orifice plates.

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

Dynamic Simulation Sled Testing

2013-10-29
CURRENT
J2481_201310
Dynamic simulation sled testing can represent various automotive collision conditions. Acceleration conditions during sled testing are readily reproducible and can be tuned to simulate collision events that occur during vehicle impacts with a fixed barrier or vehicle. Sled tests are conducted on automotive vehicle bodies or other structures to obtain valuable information. This information can be used to evaluate the dynamic performance of, but not limited to, vehicle restraint systems, vehicle seating systems, and body closure systems.

Definition for Particle Size

1981-07-01
HISTORICAL
J391_198107
'Effective particle or domain size' is a phrase used in X-ray diffraction literature to describe the size of the coherent regions within a material which are diffracting. Coherency in this sense means diffracting as a unit. Small particle size causes X-ray line broadening and as such can be measured. It has been shown related to substructure as observed in transmission electron microscopy. Particle size is affected by hardening, cold working, and fatigue; conversely, there is increasing evidence that particle size, per se, affects both static and dynamic strength.
