Applications
The test capabilities of a Series 4400 instrument range
from simple tension or compression testing with a record-
ing of specimen loading versus time, to more advanced
techniques, including modulus tests, relaxation-recovery,
and cyclic evaluations involving detailed calculations and
data analysis. This flexibility is possible due to a broad se-
lection of options available for use with a basic system.
For example, with the recorder and printer options,
graphic plots and recordings of load versus extension or
strain can be obtained. The Display Panel allows the
peak and break parameters of load, extension and strain
to be monitored and stored. The Limits Panel permits
minimum and maximum travel limits of the crosshead to
be controlled at selected load, stress, extension or strain
values. This enables cyclic evaluations of materials dur-
ing relaxation and recovery. The Limits Panel can also
provide rapid return of the crosshead to gauge length af-
ter break for repetitive specimen testing.
Additionally, each Series 4400 instrument has built-in
preset points and integration capabilities for the evalu-
ation of energy related properties, such as Tensile En-
ergy Absorption (TEA) and elastic modulus. The wide
variety of materials testing applications for a system in-
cludes:
PLASTICS - perform tests to ASTM-D638 and ASTM-
D1623 to obtain tensile strength, percent elongation,
modulus of elasticity, and peak and break values of load
and strain. Perform flexural tests to ASTM-D790 for pa-
rameters such as maximum force, maximum fiber stress,
flexural strength, tangent and secant modulus, and stress at
