The terms included in the Glossary are general in nature and usually apply to more than one manufacturer's system. All terms apply to automotive restraint systems which are initiated by an electric squib upon receipt of a signal from a remotely mounted sensor. These terms are intended to reflect existing designs and the Glossary will be updated as information on other types of systems becomes available. Two different formats are used to present the terms. A standard alphabetical approach is provided to allow a user to quickly find the definition of a particular term. The information is also repeated in a second format which groups the terms into functional areas. This technique will allow the Glossary user to develop a better understanding of the design and functioning of an automotive inflatable restraint system.
The terms included in the Glossary are general in nature and may not apply to all manufacturers’ systems. All terms in Section 3 apply to automotive inflatable restraint systems in general which are initiated by an electric or mechanical stimulus upon receipt of a signal from a sensor. These terms are intended to reflect existing designs and the Glossary will be updated as information on other types of systems becomes available. Appendix A is included to identify terminology that is no longer in common use or specifically applicable to inflatable restraint systems, but was published in the December 2001 version of SAE J1538.

The purpose of this SAE Recommended Practice is to provide guidelines for selection of transducers, data acquisition systems, and other instrumentation as well as analysis methods to help ensure proper measurement and evaluation of acoustic impulses in automobiles. While this Recommended Practice focuses on automotive inflatable devices, such as, frontal airbag systems, pretensioners, inflatable curtains, side airbags, etc, it can be used for measurement of other impulsive sounds in a vehicle if needed. The objective is to achieve uniformity in instrumentation practice and reporting of test measurements. Use of this recommended practice should provide a basis for meaningful comparisons of test results from different sources. This recommended practice specifies procedures for static measurement of acoustic impulses, but due to the much more complicated nature of crash testing, does not specify procedures for measuring impulses in vehicles during crash tests.

This SAE Information Report provides basic information about supplemental air bag systems. This report is made available by SAE as a service to the public to explain the value of these systems as they improve the safety of motor vehicles. It also addresses some misconceptions and answers many questions about the operation of air bag systems.
This recommended practice describes a method for identification of air bag equipped vehicles requiring minimal knowledge of vehicle design or air bag system configuration.
This SAE Recommended Practice describes the method for safe deployment of air bag modules in vehicles equipped with electrically actuated air bag systems for the purpose of disposal. It is intended to provide a procedure which does not require significant technical expertise, is easy to operate, and is readily available, to be used by automobile dismantlers or vehicle shredders to deploy air bag modules prior to automobile reclamation.

New methods are available to assist in evaluating the risk of impulse noise-induced hearing loss from inflatable devices, for example, airbags and seat belt pretensioners. This document presents some background on impulse noise measurement techniques and assessment criteria. Related information relative to test details, for example, preamplifier specifications and filtering methods and criteria, will be discussed in a future recommended practice.

This SAE Recommended Practice establishes a ballistic tank test procedure for evaluating inflator assemblies used in inflatable restraint systems. It is intended to be a general procedure for repetitive testing and suggests only general guidelines for the safe conduct of tests and data correlation. Uniform test requirements, test procedures, and data recording requirements are specified. The intent of the document is to provide a procedure employing a ballistic tank test method for determining the ability of an inflator to meet requirements for deploying inflatable restraint systems. A ballistic tank test is described which will yield repeatable and comparable results for evaluating a given inflator configuration's pressure output versus time. Use of the ballistic tank test for comparison of various inflator technologies may be of limited value due to differences in gas temperature, gas composition and mass flow effects on airbag performance as it relates to occupant protection.
This SAE Recommended Practice describes a method to be used for the static deployment of airbag module assemblies. The results obtained from the deployment tests will be used to verify compliance with design requirements and/or specifications. The intent of this procedure is to describe recommended test methods to evaluate performance characteristics of driver airbag modules, passenger airbag modules, or other airbag modules (e.g., side airbags (door or seat mounted), roof rail airbags, knee bolster airbags, etc.). Performance limits or acceptance criteria are not established as they are typically defined based on specific vehicle design requirements. It is intended to be a general procedure for repetitive testing and suggests only general guidelines for the safe conduct of tests and reliable data correlation.
