Impact Test Apparatus Model MT 094

Impact Test Apparatus Model MT 094

– Charpy notched-bar impact test
– classic method from destructive materials testing for quality control and analysis of the fracture behavior of metallic materials

Item Description

In the field of industrial quality control, the impact test is a widely used test method with which to quickly and easily determine characteristics for a material or component analysis.

Sci-tech Impact Test Apparatus Model MT 094 experimental unit is a solid-pendulum impact tester, designed for the Charpy notched-bar impact test. The clean layout and simple operation mean the experimental sequence can be observed in all details and phases.

In the experiment, the hammer attached to a pendulum arm describes an arc. At the lowest point of the hammer path, the hammer transfers part of its kinetic energy to the notched specimen. The specimen is either destroyed or bent by the impact and pushed between the supports.

The notched-bar impact work required to deform the specimen is read directly off a large scale.

Technical Specifications

1. Classic Charpy notched-bar impact test
2. Pendulum impact tester
3. Hammer mass can be varied by adding or removing weights
4. Brake to reduce the residual energy
5. Safe operation thanks to two-hand release of the hammer and protective ring for the operating area
6. Protective cover available as an accessory
7. Scale for displaying the notched-bar impact work
8. Notched-bar impact specimens: aluminium, copper, steel, brass
9. Optional System for data acquisition
