izod impact testing machine pdf

 • 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 and the height of rise after 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 lifting in to the pendulum and on to
 the base of the machine for Izod. Charpy test, Changing from one striker to another is achieved simply by

 fixing the new striker into it's position.

• This impact tester offered with 300 J 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 the standard test specimens supplied NIST, USA.
• All two sets of the five specimen mu
• Caliper gauge for checking V notch for Izod & Charpy.
• Templates for checking 10 x 10 mm cross section of Izod / Charpy test specimen.
• Izod support for 0.450 dia Izod round specimen.
• Self centering tong for quick and accurate setting of Charpy test specimen.
• 'V' notch milling cutter
• 'U' notch milling cutter
• Depth notch gauge including V & U notch gauges for checking depth blow V/U
 notch, angle and radius.
