DIMENSIONAL AND PERFORMANCE SPECIFICATION FOR AFTER-MARKET GASOLINE ENGINE OIL FILTERS

2021-05-13

CURRENT

USCAR36-1

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 typical 10000 mile oil change intervals. Some OEM engines may require special filters for which this specification would not support. Filters that meet or exceed this specification requirements for both dimensional and performance can claim “Conformance to SAE/USCAR - 36 Specifications.” Filters that meet just the performance specifications (ie. may have different thread) can claim “Aligns to SAE/USCAR - 36 Performance Specifications.”

PERFORMANCE SPECIFICATION FOR AUTOMOTIVE WIRE HARNESS RETAINER CLIPS

2021-01-20

HISTORICAL

USCAR44-1

This specification describes a method and acceptance criteria for testing automotive wire harness retainer clips. Retainer clips are plastic parts that hold a wire harness or electrical connector in a specific position. Typical plastic retainers work by having a set of “branches” that can be inserted into a hole sized to be easy to install but provide acceptable retention. This specification tests retainer clips for mechanical retention when exposed to the mechanical and environmental stresses typically found in automotive applications over a 15-year service life. This specification has several test options to allow the test to match to the expected service conditions. The variability of applications typically arises from different ambient temperatures near the clip, different proximity to automotive fluids, different exposure to standing water or water spray, and different thicknesses of the holes that the clip is inserted into.

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.

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.

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.
