The
pendulum Impact Tester, Model IT-30 is
designed for conducting Izod, Charpy test. The test methods confirm to
BS : 131 : Part 4-1972 (Amended 15 Aug.
1993)
BSEN : 10045-2 : 1993 & ASTM :
E-23-94a.
The Pendulum is mounted on antifriction
bearings. It has two starting positions,
the upper one for Charpy & the lower
one for Izod testing. On release, the
pendulum swings down to brake the
specimen and the energy absorbed in
doing so is measured as the difference
between the height of drop before
rupture of the test specimen and is read
from the maximum pointer position on the
dial scale.(It is read on digital readout in case
of electronic machines.)
There are two strikers and one combined
support available for fitting in to the
pendulum and on to the base of the
machine for the Izod, Charpy test respectively, Changing
from one striker to another is achieved
simply by fixing the new striker into
it's position.
Charpy
Test :
The charpy test piece rests on alloy
steel support anvils, fitted on the base of
the machine rigidly held in position by
Allen screws. End stopper is provided
for quickly and accurately locating the
test piece centrally between the
supports.
Izod Test :
The Izod test is clamped vertically
in Izod support fitted on the base of
the machine. The support is provided
with a machined vertical groove to suit
the test piece size. The front clamp
piece and the Allen screw enable
clamping of the test piece in correct
height with the help of Izod setting
gauge supplied.
Impact Testing Machines
Model IT-30 (ASTM) :
This impact tester offered with 300J energy exclusively for Charpy test confirming to ASTM E-23. This machine is geometrically checked in the works to the more stringent requirements of the American standard. The accuracy of the machine is then verified by PROOF TEST by testing standard test specimens supplied the NIST, USA. Two sets ( Low & high energy-1 Set (4 Nos.) each.) must agree with the normal values within certain tolerance specified.
