it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version

DISCUSSION—
For inflatable restraints, practices for conducting accelerated aging are designed to determine the aggravated effects on a fabric from exposures to heat,
humidity, or ozone, or a combination thereof. These environmental conditions may also be cycled in combination. The four accelerated aging
procedures of concern to the design and manufacture of inflatable restraints are referred to as cycle aging, heat aging, humidity aging, and ozone aging.
adhesive failure, n—for inflatable restraint sealed and sewn seams, a failure of seam sealant at the interface of two substrates
where the sealant is sheared such that a portion of the sealant greater than 90 % of the original thickness of the sealant layer
must remain attached to one of the two substrate surfaces, while a portion of the sealant less than 10 % of the original thickness
of the sealant layer must remain attached to the other of the two substrate surfaces.
air splice, n—for inflatable restraint fabrics, the thicker portion of a yarn resulting from the entanglement of the filaments at the
ends of two multifilament yarns to create a continuous yarn.
average dynamic air permeability (ADAP), n—for inflatable restraints, the average of all of DAP measurements within a
specified range of pressure differentials.
bleedthrough, n— for coated inflatable restraint fabrics, the presence of coating material on the uncoated side, between two yarns,
without covering either yarn.
blip, n—for inflatable restraint fabrics, any short, irregularly shaped or textured portion of an individual multifilament yarn that
has been woven into the fabric, including slough offs, stripbacks, fuzz balls, snarls, and slubs.
breakout pressure, n— for inflatable restraints, the pressure level during deployment which ruptures the module cover.
broken filament, n— for inflatable restraint fabrics, an individual filament, separated from a multifilament yarn bundle, that lies
on the surface of the fabric.
