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.

ERGONOMICS SPECIFICATION FOR MANUALLY SEATED FASTENERS
2020-12-30
CURRENT
USCAR47
This document describes the assembly force guidelines for manually seated push-pins, clips, and similar retention devices. For the purpose of this document, the term “clip” is used to reference all retention devices addressed within this document. Applicable retention devices must have force exerted directly to the clip using the finger/thumb and are hand seated independent of other fasteners. For a retention device to be manually installed and seated independent of other retention devices, it must be seated fully without any interaction with an adjacent fastener (i.e., multiple PIA clips on the back of a hard trim panel). This standard applies to contact surfaces angled at 90 degrees (±10 degrees) and/or perpendicular from the direction of force insertion. Mechanically installed fasteners (screws, rivets, etc.) are not included in this document. This standard does not apply to extraction/retention forces.

SPECIFICATION FOR TESTING GAS DISCHARGE LIGHT SOURCE SUBSYSTEM
2022-03-02
CURRENT
USCAR27-1
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.
