Standard Test Method for Determining Dynamic Air Permeability of Inflatable Restraint Fabrics
 N D6476

Annotation

This test method covers the procedures used to determine under dynamic airflow conditions the high pressure permeability of permeable, uncoated fabrics typically used for inflatable restraints. For the determination of air permeability of inflatable restraint fabrics under low pressure conditions at steady-state air flow, refer to Test Method D737.

Procedures and apparatus other than those stated in this test method may be used by agreement of purchaser and supplier with the specific deviations from the standard acknowledged in the report.

The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

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 and health practices and determine the applicability of regulatory limitations prior to use.

Стандартный метод тестирования для определения динамической воздушной проницаемости надувных матриц ограничения

Эти покрытия метода тестирования процедуры, используемые для определения под динамическим потоком воздуха, обусловливают проницаемость высокого давления проницаемых, непокрытых матриц, обычно используемых для надувных ограничений. Для определения воздушной проницаемости надувных матриц ограничения при низких условиях давления в установившемся воздушном потоке отошлите к Методу тестирования D737.
