Standard Test Method for
Breaking Strength and Elongation of Textile Fabrics (Grab
Test)1

This standard is issued under the fixed designation D 5034; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of the last revision. A number in parentheses indicates the year of the last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.

1. Scope

1.1 This test method covers the grab and modified grab test
procedures for determining the breaking strength and elongation of most textile fabrics. Provisions are made for wet testing.

1.1.1 The grab test procedure is applicable to woven,
nonwoven, and felted fabrics, while the modified grab test
the procedure is used primarily for woven fabrics.

1.2 This test method is not recommended for glass fabrics,
or for knitted fabrics and other textile fabrics which have high
stretch (more than 11 %).
NOTE 1—For the determination of the breaking force and elongation of
textile fabrics using the raveled strip test procedure and the cut strip test
the procedure, refer to Test Method D 5035.

1.3 This test method provides the values in both inch-pound
units and SI units. Inch-pound units are the technically correct
name for the customary units used in the United States. SI units
is the technically correct name for the system of metric units
known as the International System of Units. The values stated
in either acceptable metric units or in other units shall be
regarded separately as standard. The values stated in each
system may not be exact equivalents; therefore, each system
must be used independently of the other, without combining in
any way.

1.4 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.
