Test Procedures for Evaluating Bolt-Load Retention of Magnesium Alloy

2018-11-02
WIP
USCAR35-1
1.1 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. 1.2 The test procedures provides guidance in the following areas: (a) BLR sample and test fixture, (b) test fastener, washer and nut, (c) bolt-load measurement and data acquisition, (d) heating device, (e) initial loading, (f) baseline test, and (g) instrumentation of strain gages and calibration (see Appendix B).

SPECIFICATION FOR TESTING GAS DISCHARGE LIGHT SOURCE SUBSYSTEM

2007-10-08
CURRENT
USCAR27
This specification is a general level subsystem light source specification that establishes test requirements of a Gas Discharge Light Source (GDLS) subsystem for use on passenger vehicles. The completed test data to this test specification is intended to be provided to the OEM by the Tier one lamp set maker as part of the lamp assembly PPAP. Re-testing shall be required if any portion of the approved GDLS experiences a design, manufacturing or component change. This document shall be applied to systems that meet the requirements for design, performance and validation established by government standards. The subsystem is defined as the ballast, igniter and light source and shall be tested as a subsystem and considered one test sample for the entire test sequence. A failure of any component in the test sample shall constitute a failure of the entire sample. Substitution or replacement of only the light source shall be allowed during testing.

Test Procedure for Electrical Ground Attachments

2003-09-18
CURRENT
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

CURRENT
USCAR32
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.

Test for Evaluating the Torque-Tension Relationship of Both External and Internal Metric Threaded Fasteners

1998-12-30
HISTORICAL
USCAR10
This standard provides a test method for determining the torque-tension relationship of both external and internal metric threaded fasteners for the purpose of measuring the frictional characteristics of the threaded fasteners. The results obtained by this test are relevant to the test conditions only and should not be utilized for specific applications. The test shall consist of a single installation of the sample fastener in a test fixture using a DC electric power tool. The test sample shall be assembled onto an appropriate mating test part (i.e., a nut will be tested by being driven onto a test screw). The test sample shall be driven against a test washer as the bearing surface.
