Cyclic corrosion and media contamination effects during inertia dynamometer testing on torque output, coefficient of friction, surface condition, for passenger cars and light duty trucks up to 4540 kg of Gross Vehicle Weight Rating.

The acquisition of digital evidence from automobiles has become commonplace, with the number of data sources within vehicles continually growing. To that end, the potential for evidence spoliation is real in that the acquisition of data from one source could interfere with the data stored in another source. The purpose of this recommended practice is to provide information to assist in eliminating or at least minimizing the potential for evidence spoliation and also providing guidance as to when decisions must be made to prioritize the order of data collection.

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.

This SAE Standard covers the minimum requirements for nonmetallic tubing as manufactured for use in air brake systems which tubing is different from that described in SAE J844. It is not intended to cover tubing for any portion of the system which operates continuously below - 40 degrees C or above +93 degrees C, above a maximum working gage pressure of 1.0 MPa, or in an area subject to attack by battery acid. This tubing is intended for use in the brake system for connections, which maintain a basically fixed relationship between components during vehicle operation. Coiled tube assemblies required for those installations where flexing occurs are covered by this document, SAE J1131 and SAE J2494-3, to the extent of setting minimum requirements on the essentially straight tube and tube fitting connections which are used in the construction of such assemblies.

Best Practices for defining the dimensional requirements of backing plates on the drawings themselves, and defining the measuring procedures used to validate those dimensions. The proposed standard employs already established methods such as geometric dimensioning and tolerancing (GD&T), including instruction on its proper application to features specific to backing plates. Current ‘best practices’ of design and drafting in our industry are similarly highlighted; drawing clarity, revision control, and dimensioning for both function and manufacturability. Generic examples are used to illustrate both the advantages of best drafting practices, and the potential failure modes that can result from poor drafting practices. The standard also proposes the best methods of measurement required to properly validate requirements such as feature size and location, surface roughness, plate flatness and bow shape

The scope of this new recommended practice should include, but not necessarily be limited to: 1. Define vehicle operating conditions used to drive MOC-EPB actuator design and selection 2. Define brake corner operating conditions (e.g. temperature and state of burnish) used to drive MOC-EPB actuator design and selection 3. Define actuator operating conditions (e.g. temperature, voltage, current limit, and state of wear) used to drive MOC-EPB actuator design and selection 4. Define methodology for addressing part to part variation in performance

To develop a recommended practice for taking photographs of a damaged vehicle to preserve evidence.

This SAE Aerospace Information Report is to supplement content from ARP4163 pertaining to error analysis on the use of multiple drive adapter applications, on both vertical and horizontal balance machines. This new Aerospace Information Report will serve as a practical resource that offers guidance to the Machine Operator and Process Engineer.

to provide industry with a reference document highlighting the necessary design considerations and configuration option for an aircraft fully enclosed test facility (Hush House).

The goal of this new document is to provide criteria for managing, auditing, and controlling the use of rotating balancing tooling and associated support tools. A variety of subjects will be addressed including serialization and marking requirements, critical inspection criteria, performance tracking through tooling compensation trend analysis, handling of gage standards (rotor simulators, master blades, dummy blades, etc.), recommendations for periodic and preventive maintenance intervals, test recommendations to evaluate rotating tooling performance, requirements for traceable measures (such as torques, runouts, eccentricity, etc.), repeatability characterization, and criteria for return to service.

This document describes the assessment methods and physical requirements associated with the manual handling of carts and dollies, specific to material handling systems. All possible designs and applications could not be anticipated in creating these guidelines. Where there are questions of adherence to this document, such as use of an “off-the shelf” design, always consult the responsible Ergonomics Department. Force guidelines were primarily developed referencing the push/pull psychophysical Snook data contained in A Guide to Manual Materials Handling (second edition) by Mital, Nicholson and Ayoub (NY: Taylor & Francis, 1997). The force guidelines accommodate 75% of female capabilities and 99% of male capabilities. Factors that were included in the established guideline include: push / pull distances, vertical hand height, horizontal hand height, frequency and wheel / castor alignment and load rating. These factors were used to develop a conservative force guideline.

The materials defined by this U.S. CAR / S.A.E Recommended Practice are low VOC water based coatings for automotive tooling and general maintenance.

SAE J1698-1A creates an appendix to SAE J1698-1. The appendix contains EDR Record parameters and definitions related to light duty passenger vehicle pedestrian protection systems.

The materials defined by this SAE Standard are unreinforced thermoplastic acetal and thermoplastic 6/6 heat stabilized nylon, as both materials will function in this application. The specific material chosen will depend on the final application's surroundings and heat requirements. They are for use in vacuum booster check valves for hydraulic brake systems.
