ASTM D5446 physical properties of fabrics, yarns, and sewing thread used in inflatable restraints 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 via the ASTM D5446 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 via the ASTM D5446 in the manufacturer of inflatable restraints may be either flat or one piece woven. For the one-piece woven, follow the sampling section of ASTM D5446 and the individual test method. ASTM D5446 physical properties of fabrics, yarns, and sewing thread used in inflatable restraints practice may be used in conjunction with Practice ASTM D5427 which prescribes standard practices for the accelerated aging of inflatable restraint fabrics when comparative results of physical properties before and after accelerated aging are required.
