Standard Test Method for Determining Specific Packability of Fabrics Used in Inflatable Restraints

Importancia y uso:

5.1 This test method is useful for determining the specific packability of uncoated and coated airbag fabrics. Fabric packability is an important factor in the design of airbag modules due to their inherent spacial constraints.

5.2 A folded specimen exhibits better specific packability if it occupies a lower total volume at the specified loads compared to another specimen.

5.3 The time required to test one sample (four specimens from the same lot of fabric) is approximately 1.5 h using this test method. Due to the length of time required by this test method to perform a single test, this test method is most suitable for use in design and development analysis or for inclusion in a list of required tests conducted for annual certification of an airbag fabric.
