Product Code:SAE USCAR17
Title:Performance Specification for Automotive RF Connector Systems
Issuing Committee:
Scope:Procedures included within this specification are intended to cover performance testing at all phases ofdevelopment, production, and field analysis of electrical terminals, connectors and components for coaxial cableconnection systems (hereafter referred to as RF connectors) intended for road vehicle applications.2. The intent of this specification is to qualify RF connectors that operate at frequencies from 70 MHz to 3 GHz.The characteristic impedance of the SMB/FAKRA connection system is 50 ohms however this specification doesnot exclude the use of these RF connectors on non-50 ohm cables or systems.3. This specification does not apply to single conductor wire or twisted pair connection systems.4. This specification (along with SAE/USCAR 18 and SAE/USCAR 19) is designed to provide the mechanical andelectrical data required to insure that assemblies from various manufacturers will perform reliably in actualconditions. There is no specific intermateability testing included, however. End users who may be concernedabout intermateability are responsible to work directly with their suppliers to address these concerns.Product Code:SAE J1204
Title:Wheels-Recreational and Utility Trailer Test Procedure
Issuing Committee:Wheel Standards Committee
Scope:This SAE Recommended Practice provides uniform procedures and minimum performance requirements for fatigue testing ferrous and aluminum wheels intended for normal highway use on travel, camping, and boat and light utility trailers drawn by passenger cars, light trucks, and multipurpose vehicles. (See Figures 1 and 2.) For procedures and minimum performance requirements for wheels used on trucks, see SAE J267, and for wheels used on passenger cars, see SAE J328. For the application of passenger car and light ruck wheels [inset less than 0.10 m (0.33 ft)] to this trailer service, use this procedure. For the application of heavier truck wheels [inset 0.10 m (0.33 ft) or mre] use SAE J267. Mobile home service is outside the scope of this document.There are two basic test procedures described, a cornering fatigue test and radial fatigue test. The cornering test is directed at the wheel disc; whereas the radial test also examines the rim and attachment portion of the wheel. Both test procedures are required to obtain a thorough examination of the wheel.
