PERFORMANCE SPECIFICATION FOR AUTOMOTIVE RF CONNECTOR SYSTEMS

2023-07-10
CURRENT
USCAR17-6
This document contains procedures for testing performance of SMB-style electrical terminals, connectors and components for coaxial cable connection systems intended for road vehicle applications. These are often called FAKRA II designs. This specification does not apply to the Non RF portion of a Hybrid RF connection system. The intent of this specification is to qualify sealed and unsealed RF connectors that operate at frequencies from DC to 6 GHz. The characteristic impedance of the SMB/FAKRA connection system is 50 ohms however this specification does not exclude the use of these RF connectors on non-50 ohm cables or systems. This specification does not apply to single conductor wire or twisted pair connection systems. This specification (along with SAE/USCAR 18) is designed to provide the mechanical and electrical data required to insure that assemblies from various manufacturers will perform reliably in actual conditions.

PERFORMANCE SPECIFICATION FOR AUTOMOTIVE WIRE HARNESS RETAINER CLIPS

2023-03-23
CURRENT
USCAR44-2
This specification describes a method and acceptance criteria for testing automotive wire harness retainer clips. Retainer clips are plastic parts that hold a wire harness or electrical connector in a specific position. Typical plastic retainers work by having a set of “branches” that can be inserted into a hole sized to be easy to install but provide acceptable retention. This specification tests retainer clips for mechanical retention when exposed to the mechanical and environmental stresses typically found in automotive applications over a 15-year service life. This specification has several test options to allow the test to match to the expected service conditions. The variability of applications typically arises from different ambient temperatures near the clip, different proximity to automotive fluids, different exposure to standing water or water spray, and different thicknesses of the holes that the clip is inserted into.

DIMENSIONAL AND PERFORMANCE SPECIFICATION FOR AFTER-MARKET GASOLINE ENGINE OIL FILTERS

2021-05-13
CURRENT
USCAR36-1
This specification defines the dimensional and performance requirements for aftermarket spin-on oil filters intended for use on gasoline engines. Filters meeting this specification may also be suitable for use on some diesel applications. Filters meeting these dimensional limits are intended to meet the oil filter fit and package requirements for engine and vehicle designs. Filters meeting the performance requirements are intended to maintain sufficient durability to support typical 10000 mile oil change intervals. Some OEM engines may require special filters for which this specification would not support. Filters that meet or exceed this specification requirements for both dimensional and performance can claim “Conformance to SAE/USCAR - 36 Specifications.” Filters that meet just the performance specifications (ie. may have different thread) can claim “Aligns to SAE/USCAR - 36 Performance Specifications.”

CURRENT
USCAR12-6
This document gives specific and measurable design requirements to be applied at a design review prior to tooling. The specification is formatted as a checklist to aid in its use. The requirements do not apply in all situations so engineering judgment must be used. This is a specification for design; applicable performance specifications (USCAR-2, etc.) must still be performed. Specific requirements in this document are grouped by component using a prefix as shown in Table 1 and are numbered by an item number following the prefix.

TEST PROCEDURES FOR EVALUATING BOLT-LOAD RETENTION OF MAGNESIUM ALLOYS

2020-11-19
CURRENT
USCAR35-1
A bolt-load retention (BLR) test is a practical test to determine the bolt load of a fastener joint with time and at given temperatures. There are three types of BLR tests described in this standard, namely general-purpose test, design-purpose test, and screening material test. A general-purpose BLR test may be used for screening materials, while a design-purpose BLR test is usually used to verify the BLR behavior of a specific joint. The screening material test is an example of the general-purpose test for typical automotive applications.

CURRENT
USCAR32-1
This standard lists variables that shall be investigated and reported as an initial investigation into new or revised surface finishes intended for use on fasteners. This standard provides instruction for producing a final report that will be used to determine if further investigation of a surface finish is justified. Further investigation may include tests and evaluations specific to an individual OEM prior to introduction/approval of the surface finish. The final report shall include the results, observations, and conclusions for all of the variables. The final report may be made up of several individual reports covering each variable. In all cases the laboratory performing the test, the test date and the report approver shall be included in the final report.

CURRENT
USCAR39-1
This standard describes a requirement for automotive tire traceability. It includes a definition of the RFID tag and the associated tire data set that can be accessed using the RFID tag as an identifier. The standard describes a unique identification and the associated data set for each tire produced by the tire fabricator. This data will either be provided or transmitted at the time of shipment to retailers, wholesalers or original equipment vehicle manufacturers. Tire identification code and data may be used for error proofing, determining the tire specifications or supporting any inquiries that occur for the duration of its automotive life.

PERFORMANCE SPECIFICATION FOR CABLE-TO-TERMINAL ELECTRICAL CRIMPS

2020-01-22
CURRENT
USCAR21-4
This specification defines test methods and requirements for validation of solderless crimped connections. The purpose of this test is to simulate in the lab the stress seen in a typical life (15 years and 150000 miles) for a crimp connection and assure the crimp is mechanically strong and electrically stable. This specification was developed for use with stranded automotive copper wire. Only where specifically mentioned are other constructions or other core materials (aluminum, clad, steel core, etc.) applicable. This specification does not apply to wire types not mentioned, such as coaxial cable crimps, unless a USCAR-21 test is specifically referenced in the test specification for that wire type.

PERFORMANCE SPECIFICATION FOR ULTRASONICALLY WELDED WIRE TERMINATIONS

2016-04-05
HISTORICAL
USCAR38-1
This specification defines test methods and performance criteria for evaluating ultrasonically welded wire-to-terminal metallurgical bonds. The examples used are specific to the linear weld type of process equipment. USCAR-38 is not applicable for “Splice Welding”. The specification is applicable to wire-on-pad configurations with a typical weld shown in Figure 1. This test specification subjects parts under test to environmental exposures to simulate a lifetime of field exposure for a road vehicle. Exposures called-out in this specification include Thermal Shock, Temperature Humidity Cycling and mechanical abuse. This test specification is intended to evaluate the strength and performance of the interface between wires to an electrical terminal. Validation of the performance of the Terminal is a separate task and can be accomplished using a component validation test such as SAE/USCAR-2, which evaluates whether the entire connection system is acceptable.
