AUTOMOTIVE GRADE COAXIAL CABLE PERFORMANCE SPECIFICATION

2022-03-15

CURRENT

USCAR29-1

This document specifies dimensional, functional and visual requirements for Automotive grade coaxial cable. This material will be designated AG for general-purpose automotive applications or AG LL for low loss applications. It is the responsibility of the user of this cable to verify the suitability of the selected product (based on dimensional, mechanical, electrical and environmental requirements) for its intended application. It is the responsibility of the supplier to retain and maintain records as evidence of compliance to the requirements detailed in this standard.

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.

TORQUE-TENSION TESTING AND EVALUATION OF FASTENER FINISHES

2020-11-19

CURRENT

USCAR11-2

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.

GRAIN FLOW PATTERN FOR BOLTS, SCREWS, AND STUDS

2019-03-14

CURRENT

USCAR8-4

This specification covers the grain flow pattern requirements in headed bolts, screws, and studs. The heading practice in the manufacture of the bolt, screw, or stud sets the grain flow pattern, but it is also greatly influenced by the fastener and tooling design as well as cold-forging setup. The use of tooling design simulation software is recommended and a commonly used practice that provides reliable forging predictions for superior grain flow quality.

USCAR21-2

In any intended vehicle application, if the products covered by this specification are, or may be, subjected to conditions beyond those described in this document, they must pass special tests simulating the actual conditions to be encountered before they can be considered acceptable for actual vehicle application. Products certified by their supplier as having passed specific applicable portions of this specification are not to be used in applications where conditions may exceed those for which the product has been satisfactorily tested. The Authorized Person is the final authority as to what tests are to be performed on his or her parts and for what purpose these tests are required. He or she is also the final authority for resolving any questions related to testing to this specification and to authorizing any deviations to the equipment or procedures contained in this specification.

Avoidance of Hydrogen Embrittlement of Steel

HISTORICAL

USCAR5-2

This standard outlines the conditions that enhance the risk of hydrogen embrittlement of steel and define the relief procedures required to minimize the risk of hydrogen embrittlement. It is intended to control the process. 1.1 Hydrogen embrittlement of steel, which can cause brittle fractures under stress, occurs as a result of the absorption of hydrogen during cleaning, phosphate coating and plating processes. The susceptibility to hydrogen embrittlement increases with increasing stress (internal or externally applied stress) and increasing material strength. 1.2 Hardness readings in this specification are in Vickers scale. SAE J417 should be referred to for conversion to other scales. NOTE 1: All references to temperatures relate to part core temperature and not the indicated oven air temperature. Statistical data of verifications in temperature at the center of the oven load and oven temperature shall be established to develop the oven profile.
