Standard Terminology of
Force, Deformation, and Related Properties of Textiles1

This standard is issued under the fixed designation D 4848; 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 last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.

1. Scope

1.1 This terminology standard is a compilation of definitions of technical terms related to force and deformation
properties when evaluating a stress-strain curve of a textile.
(See Figs. X1.1 and X1.2.) A chart showing the relationship of
the basic terms is shown in Table 1. Terms that are generally
understood or adequately defined in other readily available
sources are not included.

1.2 For other terms associated with textiles, refer to Terminology D 123.

3. Terminology

breaking elongation—See elongation at break.
breaking force, n—the maximum force applied to a material
carried to rupture. (Compare breaking point, breaking
strength. Syn. force-at-break)
DISCUSSION—Materials that are brittle usually rupture at the maximum force. Materials that are ductile usually experience maximum
force before rupturing.
breaking load—deprecated term. Use the preferred term
breaking force.
the breaking point, n—on a force-elongation curve, or stress-strain curve, the point corresponding with the braking force
or the breaking stress in a tensile test. (Compare breaking
breaking strength, n—strength expressed in terms of breaking
force. (See also breaking force and strength. Syn., strength
at break)
breaking tenacity, n—the tenacity at the breaking force. (See
also breaking force, tenacity.)
breaking toughness, n—toughness up to the breaking force of
a material.
DISCUSSION—Breaking toughness is represented by the area and the
stress-strain curve from the origin to the breaking force per unit length,
