Balancing Machines - Tooling Management, Audit, and Control

2015-12-21
WIP
ARP6898
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.

HISTORICAL
J2834_201904
This recommended practice defines methods for the measurement of periodic, random and transient whole-body vibration. It indicates the principal factors that combine to determine the degree to which a vibration exposure will cause discomfort. Informative appendices indicate the current state of knowledge and provide guidance on the possible effects of motion and vibration on discomfort. The frequency range considered is 0.5 Hz to 80 Hz. This recommended practice also defines the principles of preferred methods of mounting transducers for determining human exposure. This recommended practice is applicable to light passenger vehicles (e.g., passenger cars and light trucks). This recommended practice is applicable to motions transmitted to the human body as a whole through the buttocks, back and feet of a seated occupant, as well as through the hands of a driver.

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.

SURFACE MATCH VERIFICATION METHOD FOR PRESSURE SENSITIVE ADHESIVELY ATTACHED COMPONENTS

1991-12-01
HISTORICAL
J2215_199112
This SAE Recommended Practice applies to evaluation of the conformance match condition existing between two surfaces. Evaluation of this conformance may be especially useful in bonded applications although it may also have relevance to bolted adjacent surface joint conditions. Since good bonding surface conformity is necessary for providing optimal bond performance with pressure sensitive adhesives, the purpose of this document is to provide a method of evaluating the conformance match of the mating surfaces. This document is intended as a guide toward standard practice but may be subject to frequent change to keep pace with experience and technical advances. This should be kept in mind when considering the use of this document. Tool types, materials, application tools, and component contact area evaluation methods are included as part of this document.

Measurement of Aerodynamic Performance for Mass-Produced Cars and Light-Duty Trucks

2010-06-03
HISTORICAL
J2881_201006
This recommended practice provides a procedure for measuring and documenting the aerodynamic performance in a full-scale wind tunnel of passenger vehicles, i.e., mass-produced cars and light-duty trucks intended primarily for individual consumers. Testing or numerical modeling of pre-production and/or reduced-scale models is outside the scope of this document. Aerodynamic development procedures, i.e., methods to improve or optimize aerodynamic performance, are also excluded. It is well-known that aerodynamic performance results depend significantly on vehicle content and loading, as well as the wind tunnel itself (type, scale, and simulation qualities of the wind tunnel). Publication of non-standard test results causes unnecessary additional development work and incorrect perception of a vehicle’s anticipated aerodynamic performance by government, academia, and the general public.

CURRENT
J3266_202205
The scope of this SAE Information Report is an evaluation of the ports and tools used on automotive air-conditioning systems to evacuate and charge systems with approved refrigerants during vehicle service. A task force was formed in April 2021 to perform this evaluation and concluded its work in September 2021. The scope of the task force was to evaluate issues being reported from service repair shops with air-conditionings service ports and the tools being used to connect to these ports. The task force also evaluated published SAE J Standards and discovered many of these standards did not include the necessary requirements for service ports and tools. The task force published a final report of its findings and recommendations. The report includes recommendations to correct and publish new SAE Standards related to the scope of this project.
