Electric Impact Testing Machine, Power : 1-3kw

The pendulum Impact Tester of all the above models are 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 Panel in case of digital models)

Controls of Pendulum:

The Pendulum supports in the starting positions are by a self-resetting latch. The release mechanism is operated by a lever. The pendulum release latch is operated only when this lever is operated

Strikers & Supports:

There are two strikers and one combined support available for lifting into 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 its position.

CHARPY TEST:

The Charpy test piece rests on alloy support anvils, fitted on the base of the machine rigidly held in position by Allen screws. The 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 at an incorrect height with the help of the Izod setting gauge supplied.

MODEL ME-ASTM-E-23

This impact tester offered with 300J energy exclusively for the 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 by the NIST, USA. All two sets of the five specimens must agree with the normal values within certain tolerance specified.

OPTIONAL ACCESSORIES

• Caliper gauge for checking V notch for Izod & Charpy.
• Templates for checking 10 x 10 mm cross-section of Izod / Charpy test specimen
• Depth notch gauge including V & U notch gauges for checking depth blow V/U notch, angle, and radius.
• Self-centering tong for quick and accurate setting of Charpy test specimen.
• ‘V’ notch milling cutter
• ‘U’ notch milling cutter
