ASTM D 1424 REV A Document Information:
Title
Standard Test Method for Tearing Strength of Fabrics by Falling-Pendulum Type (Elmendorf) Apparatus
ASTM International
Publication Date:
Dec 1, 2007
Scope:
This test method covers the determination of the force required
to propagate a single-rip tear starting from a cut in a fabric and
using a falling-pendulum type (Elmendorf) apparatus.
This test method applies to most fabrics including woven,
layered blankets, napped pile, blanket, and air bag fabrics,
provided the fabric does not tear in the direction crosswise to the
direction of the force application during the test. The fabrics may
be untreated, heavily sized, coated, resin-treated, or otherwise
treated. Instructions are provided for testing specimens with, or
without, wetting.
This method is suitable only for the warp direction tests of
warp-knit fabrics. It is not suited for the course direction of
warp knit fabrics or either direction of most other knitted
fabrics.
The values stated in either SI units or U.S. customary units are
to be regarded as standard, but must be used independently of each
other. The U.S. customary units may be approximate.
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.
