300 Nm Charpy and Izod Impact Testing Unit Deluxe

The 300 Nm Charpy and Izod Impact Testing Unit, to study the toughness in impact tests of stainless steel, copper (Cu), brass (Cu+Zn alloy), and aluminum specimens.

ATENG 12178 — 300 Nm Charpy and Izod Impact Testing Unit

Anodized aluminum frame and panels made of painted steel.

• The “ATENG 12178” unit is mainly composed of:
• Pendulum: 900 mm long aluminum bar for both methods, Charpy and Izod, supported
  by a stainless steel shaft anchored on two equidistant supports. This aluminum bar is
  welded to the shaft. The oscillation is provided by means of bearings implemented in
  both supports. The hammer corresponding to the method to be tested, either Charpy or
  Izod, can be screwed to its end.
• Initial angle: 150°.
  ATENG 12178 detail
• Capacity Charpy method: 160 – 300 Nm.
• Izod method capacity: 90 – 220 Nm.
• Pendulum mass: 3.55 kg.
• Hammer:
• Charpy hammer: it has a “C” shape and is used for impact tests on specimens supported horizontally at two ends. Its mass is 10 kg.
• Izod hammer is used to strike on vertically embedded specimens. Its mass is 5.45 kg.
• Charpy clamp: These are the two supports that we place on the base to place the specimen simply supported horizontally at both ends.
• Izod clamp: These are the two supports that we place on the base to place the specimen simply embedded vertically at one of its ends.
• Additional weights: set of weights that can be attached to both types of hammers.
• 2 brass weights of 1.5 kg.
• 2 steel weights of 2.5 kg.
• The test specimens for both methods provided conform to ISO-148 and ASTM E23 standards. Their specifications are as follows:
• Materials available: stainless steel, copper (Cu), and brass (Cu+Zn alloy).
• Length: 55 mm.
• Cross section: 10 x 10 mm².
  90° V-shaped centered flanges.
• Mechanical disc brake system consisting of:
  Hand brake lever.
  Toothed crown to allow brake locking.
  Mechanical brake cable.
• Aluminum brake disc of 160 mm diameter.
  Two-piston calipers.
  Brake pads.
• Locking system by nipple composed of:
  Stainless steel locking disc installed on the oscillating shaft.
  Sliding plunger with incorporated spring to facilitate its displacement.
  Bar mechanism to place the pin in safety position and release the hammer access door opening.
  Coupling element for unlocking the latch.
  Circular bar acting as a lever, disengageable.
