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.
This practice may be used in conjunction with Practice 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.
Procedures and apparatus other than those stated in this
practice may be used by agreement of purchaser and supplier with
the specific deviations from the standard practice acknowledged in
The values stated in either SI units or inch-pound units are to
be regarded separately as standard. The values stated in each
system are not exact equivalents; therefore, each system must be
used independent of the other.
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. See Note 3.
