Applications
specified strain. Use specimen dimensioning and peak
readouts to enable printouts of maximum force or stress
values. Other typical tests include: ASTM-D695 and
D1621 for compression; D732 for shear strength; D1004
for tear resistance; and D1894 for friction.
WIRE, FOIL, SHEET METAL - determine the tensile
strength of solid wire, electrical cables, and thin sheet
metal components. Also, in compression, test for crush
resistance and insulation cut throughs. Obtain offset
yield evaluations using the optional IEEE-488 Interface
and a computer. Some ASTM tests in this category in-
clude: E8 for metals; E132 for Poisson's ratio; E345 for
metallic foil; D2633 for thermoplastic insulation; and
D1351 for polyethylene insulation.
RUBBER - perform tests to ASTM-D412 to obtain peak
and break values of load and extension. Use preset
points for modulus values, and integrate the load/elonga-
tion curve to obtain energy values. Measure strain using
crosshead extension or an optional long-travel or optical
extensometer. Also, test for tear resistance to ASTM-
D624 and test O-rings to ASTM-D1414.
TEXTILES - perform tenacity and stretch tests of fab-
rics, yarns and cords. Determine load at set elongation
(LASE) using preset points. Apply specimen dimension-
ing to obtain load value relationships to units such as
grams/denier. Use a computer through the IEEE-488 in-
terface to obtain complete statistical analyses of test re-
sults. Typical ASTM textile-related tests applicable to a
Series 4400 instrument include: D458 for man-made fi-
bers: D2256 for yarn; D2653 for elastomeric yarns; and
D2263 for grab tests of automotive fabrics.
