Standard Practice for Evaluating the Performance of Inflatable Restraint Modules

2019-01-15 /Active
Significance and Use:

5.1 This practice is intended to be a general guideline for repetitive testing, safe conduct of tests, and accurate data collection for inflatable restraints.

5.2 This practice may be used by the purchaser and the supplier to establish the criteria by which inflatable restraint modules will be tested by the supplier to determine whether a lot of material is acceptable for shipment to the purchaser.

5.3 Unless otherwise specified by agreement between the purchaser and the supplier, this practice shall constitute the test conditions, procedures, and equipment by which inflatable restraint modules are deployed for testing. It is intended to be used as a guideline in establishing a written material specification or equivalent agreement between the purchaser and the supplier. The specification may deviate from the practices described herein when (based on experience) considerations of fabric properties, material handling equipment, or inflatable restraint system design dictate otherwise.


1.1 This practice describes the procedures and conditions used to evaluate the physical performance of inflatable restraint modules and module components during and after deployment.

1.2 The physical performance characteristics that may be obtained by this practice are internal cushion pressures determined by instrumentation, cushion geometries determined by high-speed photography, and material integrity determined by visual inspection.

1.3 This practice is applicable to driver and passenger side inflatable restraint modules.

1.4 Procedures and apparatus other than those stated in this practice may be used by agreement between the purchaser and the supplier with the specific deviations from the practice acknowledged in the report.

1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not exact equivalents; therefore, each system must be used independent of the other.

1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
