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.

ROAD VEHICLES – 60 V AND 600 V SINGLE CORE (ISO/METRIC) CABLES – DIMENSIONS, TEST METHODS AND REQUIREMENTS
2017-07-13
CURRENT
USCAR23-1
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”.

Grain Flow Pattern for Bolts, Screws, and Studs
2013-12-31
HISTORICAL
USCAR8-3
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 design.

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.

ENGINE OIL PUMP PERFORMANCE AND DURABILITY TEST PROCEDURES
2023-03-23
CURRENT
USCAR46
SAE/USCAR-46 defines test methods and outputs for engine oil pump bench testing. Performance and durability testing are the primary focus of this standard. This is written to specifically address testing of electronically controlled variable displacement pumps but can be adapted to mechanically controlled pumps and other pump technologies as needed. This standard outlines critical inputs and outputs in order to perform the testing and report results, but does not specifically set the acceptance standards or pass/fail criteria. Acceptance criteria must be set by the customer.
