Tensile
Tester
Instron

4501
Tensile
Tester
with
a
0.2
kN
load
cell
(or
equivalent
tensile
tester).
The
testing
machine
be
equipped
with
a
load
cell
whose
compli¬
ance
is
a
maximum
of
2%
of
the
test
specimen
extension
within
the
range
being
measured.
Digital,
as
opposed
to
ana¬
log,
self-calibrating
load
cells
are
preferred,
since
they
elimi¬
nate
the
need
for
calibration
and
potential
error
associated
with
calibrating
analog
load
cells
using
external
weights.
The
testing
machine
must
be
equipped
with
a
device
for
continu¬
ously
recording
the
tensile
load
and
the
amount
of
the
sepa¬
ration
of
the
grips;
both
of
these
measuring
systems
should
be
accurate
to
土
2%.
The
rate
of
separation
of
the
grips
be
accurate
to
±
0.1%
and
capable
of
adjustment
from
approximately
0
