This practice is a listing of the test methods commonly employed in determining the physical properties of fabrics and yarns used in the manufacture of inflatable restraints.
Fabrics used in the manufacture of inflatable restraints may be coated or uncoated, and may be comprised of spun yarns, continuous filament yarns, or a combination thereof.
Fabrics used in the manufacturer of inflatable restraints may be either flat or one piece woven. For the one-piece woven, follow the sampling section of D5446 and the individual test method.
In Section 9, this practice lists is alphabetical order the procedures associated with conducting physical testing of the following fabric or yarn properties of concern to the design and manufacture of inflatable restraints.
Thispractice may be used in conjunction with Practice D5427 which prescribesstandard practices for the accelerated aging of inflatable restraint fabricswhen comparative results of physical properties before and after acceleratedaging are required.
Proceduresand apparatus other than those stated in this practice may be used by agreementof purchaser and supplier with the specific deviations from the standardpractice acknowledged in the report.
Thevalues stated in either SI units or inch-pound units are to be regardedseparately as standard. The values stated in each system are not exactequivalents; therefore, each system must be used independent of the other.
