2002-09-09
HISTORICAL
USCAR23
This International Standard specifies the dimensions, test methods, and requirements for single core 60 V cables intended for use in road vehicle applications where the nominal system voltage is ≤ (60 V DC or 25 V AC). It also specifies additional test methods and/or requirements for 600 V cables intended for use in road vehicle applications where the nominal system voltage is > (60 V DC or 25 V AC) to ≤ (600 V DC or 600 V AC). It also applies to individual cores in multi-core cables. See ISO 6722 for “Temperature Class Ratings”.

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).

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

STANDARD FOR IN-TANK ELECTRIC FUEL PUMPS

1999-08-15
CURRENT
USCAR13
This standard covers the operational characteristics, environment, durability procedures, and test procedures for in-tank electric fuel pumps for automotive gasoline applications. Specific performance and test criteria used in conjunction with this procedure are specified on the pump drawing. Particular sections of this document may be required for all applications. This standard is intended to evaluate specific characteristics as a supplement to normal material inspections, dimensional checking, and in-process controls, and should in no way adversely influence other inspection operations.

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.

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 constant speed 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.

Dimensional and Performance Specification for After-Market Gasoline Engine Oil Filters

2013-01-30
CURRENT
USCAR36
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 many of the OEM's recommended oil change intervals. Some OEM engines may require special filters for which this specification would not support.

USCAR18-4
This document is a supplement to SAE/USCAR 17 and is intended to give recommended usages for one and two-way RF connectors and dimensional requirements for 2-way RF connectors and hybrid (RF & DC power) connectors which are not currently specified elsewhere. The radio frequency (RF) connector interface specified herein is suited for unsealed and sealed automobile applications up to 6 GHz and is intended for in-line, board mount, device mount, straight or angled applications. Dimensional requirements are specified in this document to ensure interchangeability. Compliance with the dimensional requirements of this specification will not guarantee interoperability between different suppliers mating connectors. It is the supplier responsibility to ensure RF performance requirements are met with other suppliers mating connectors. Performance requirements are specified in SAE/USCAR-2, and in SAE/USCAR-17.
