WIRING COMPONENT DESIGN GUIDELINES

2009-07-10

HISTORICAL

USCAR12-3

This document gives general guidelines to be used during the connector design stage. Various guidelines may not apply in all situations. Therefore, sound engineering judgment must be used in their application. Consider these guidelines as the basis for connector and wiring DFMEA’s. Items in this document are grouped by DFMEA functional requirements. Groups are as follows: A Electrical Continuity B Electrical Isolation/Sealing C Device Assembly D Harness Assembly E Vehicle Assembly F Materials G Serviceability H Environmental Requirements I High Voltage (≥ 60V) Application Requirements

Torque-Tension Testing and Evaluation of Fastener Finishes

1998-12-30

HISTORICAL

USCAR11

This standard provides a test method for determining the torque-tension relationship of a fastener finish as applied to a surrogate screw for the purpose of measuring the frictional characteristic of the fastener finish. The results obtained by this test shall be used as a process control attribute of the fastener finish and shall not be utilized for specific applications.

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.

TEST PROCEDURE FOR ELECTRICAL GROUND ATTACHMENTS

2022-02-25

HISTORICAL

USCAR26

This test procedure is intended to evaluate and/or validate electrical ground schemes for use on the body or chassis. There are two classes based on the expected environmental conditions. Exposed Grounds can be located anywhere in the vehicle (except on the powertrain) and is the class for which most schemes should be tested. Unexposed Grounds can only be used in the passenger compartment or trunk and as such are special cases. This procedure as written is not intended for testing powertrain grounds where high temperatures and vibration levels may be encountered. These situations may require modifications to this procedure and are left to the Responsible Engineer to determine. This specification does not specifically address validation of terminal to wire electrical crimps. Crimps are tested to SAE/USCAR-21
