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 configurations may be of limited value due to differences in gas temperature and mass flow effects on airbag performance as it relates to occupant protection.
The primary objective of the Inflatable Restraints Standards Committee (IRSC) is to utilize the experience, knowledge and technical skills of its membership to address engineering problems that fall within the scope of members’ activities and interests. IRSC members, working in small groups or within Task Forces, carry out the following tasks: • develop, implement and validate all necessary investigations and studies to prepare Technical Reports, Information Reports and Recommended Practices; • work with industry, government, academia, regulatory bodies and other SAE committees in advising, consulting and exchanging pertinent technical information and data; • periodically review and revise Technical Reports, Information Reports and Recommended Practices to maintain their technical integrity, usefulness and clarity; • assist other committees, task forces or groups that could benefit from the IRSC members’ broad technical expertise and knowledge base.
* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.

Search Tips: Search Operators:AND, OR, NOT; Wild Cards; Using Quotes
SAE MOBILUS® Search Tips
Please note: All terms not contained within quotes, will be evaluated using the OR operator. This means that your search results will contain all results that contain ANY of the entered terms.
AND, OR, NOT
SAE MOBILUS supports the use of the AND, OR and NOT BOOLEAN operators ONLY function with the Advanced Search.
Wild Cards
Using the asterisk, ( * ) allows you to search for a partial word. For example, entering a keyword search of aero* will search for any word beginning with aero.
Using the question mark, ( ? ) allows you to search for a word with a single character wildcard. For example, searching for t?re would match both tire and tyre
Using Quotes
Words in double quotes " " are treated as a phrase. Conducting a search for "heat model" will return all results in which the exact phrase "heat model" is found, while "heat modeling" would NOT be included.
A term combined with a phrase will be joined with an OR operator.
Searching for Standards
When searching for a standard please use the entire Document Number assigned, which includes the abbreviation. A space can be used, or omitted between the abbreviation and number.
