Alignment of Nut Slots
1990-01-01
CURRENT
J484_199001
This method of gaging alignment of nut slots allows equal variations for location of the cotter pin hole in the bolt and location of slots in the nut. To inspect the nut, the slotted gage is inserted through the nut hole from the bearing surface of the nut. Alignment of slots is considered satisfactory if the gage pin can be slipped into the gage and nut slots without interference.

Round Head Bolts
1990-01-01
CURRENT
J481_199001
Round head bolts are made in two body styles: (a) A full size body, with a maximum diameter somewhat greater than the nominal diameter (not an SAE Standard except for ribbed neck bolts, Table 3); and (b) an undersize body, with a minimum diameter approximating the pitch diameter of the thread and a maximum diameter never exceeding nominal (SAE standard for all types except ribbed neck bolts). The body diameter of either style may be exceeded by a reasonable swelling or fin under the head, or under corners of the square necks, to the extent that serviceability is not affected.

In-line, Elbow, and Tee Flanged Connectors for use with SAE J518-1/ISO6162-1 Components
2015-02-03
WIP
J518/4
This document standardizes the design of connector blocks used for joining SAE J518-1/ISO 6162-1 (Code 61) flange heads with other SAE J518-1/ISO 6162-1 (Code 61) flange heads with straight, elbow, and tee geometries. The blocks specified in this document are designed to provide for very compact installations. As a result, the tap depths specified in this document do not conform to those specified in SAE J518-1/ISO 6162-1 to allow for a minimal bend radius in the elbow and tee configurations. This document specifies both inch and metric configurations

Brake Dynamometer Squeal Noise Test Procedure for Regenerative Systems
2019-09-19
WIP
J3211
The SAE J3211 procedure applies to brake squeal evaluation using single-ended inertia dynamometers for friction couples used on vehicles with regenerative braking systems. This RP applies to squeal noise occurrences for on-road passenger cars and light trucks with a gross vehicle weight rating of 4536 kg or below. The procedure incorporates aspects related to (a) minimum inertia dynamometer capabilties, (b) fixture requirements and setup, and (c) test sequences with emphasis on brake temperatures, brake pressure profiles, and strategies to represent brake blending.

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.

J1888_199011
The fuses shown in Figure 1 are for use in motor vehicles, boats, and trailers to protect electrical wiring. This SAE Standard is for the construction shown and is not intended to restrict the design and use of other configurations and materials capable of meeting the vehicle requirements.

Remote Steering Control Systems
2004-08-12
CURRENT
J2588_200408
This SAE Information Report establishes a uniform procedure for assuring the manufactured quality, installed utility and performance of automotive remote steering controls other than those provided by the vehicle manufacturer (OEM). These products are intended to provide driving capability to persons with physical disabilities. The adaptive modifications seek to compensate for lost or reduced function in the extremities of the driver with a disability. Remote steering controls are designed to provide a steering input device alternative to the OEM steering wheel that either reduces the required input force, changes the required range of motion or changes the location of the steering control or any combination of the above. These controls supplement by power, other than by the driver’s own muscular efforts, the force output of the driver with a disability.

Reduced Effort Brakes and Reduced Effort Vacuum Powered Brake Backup Systems
2004-08-12
CURRENT
J2671_200408
This Information Report relates to a special class of automotive adaptive equipment which consists of modifications to the power brake booster systems provided as original equipment of motor vehicles. These modifications are generically called "Reduced Effort Power Brakes" (REPB) The purpose of the modification is to lower the amount of driver effort required to apply the brakes. Retention of reliability, ease of use and maintainability for disabled drivers, passengers, and the general public is of primary concern. Reduced Effort Power Brake modifications should be qualified by the tests referenced in the Recommended Test Procedure. The tests set forth in that procedure should be applied, and failure of a Reduced Effort Power Brake modification to meet those tests should disqualify the modification from the claim of meeting the specifications of this Information Report.
