Impact tester (pendulum impact tester) is testing machine that apply an impact to a plastic test piece and calculate the impact value from the energy of the pendulum required to break the test piece.
It is used to evaluate the characteristics of plastic materials such as impact resistance, brittleness, and tenacity.
There are various test methods such as Charpy impact test, Izod impact test, and tensile impact test.
Test methods
Specimen support/fixture methods
Testing standards
Charpy impact test
Fix both ends of the specimen to a horizontal support and impact the back of the notch (notch) with a hammer.
ISO 179 (JIS K 7111)
ASTM D6110
Izod impact test
Fix the end of the specimen in a vertical cantilevered beam and impact it with a hammer from the notched direction.
ISO 180 (JIS K 7110)
ASTM D256
Features
Digital display type eliminates abrasion loss error of the needle and reading error by the measurer.
Charpy impact test, Izod impact test, tensile impact test, etc. can be performed by changing the hammer and specimen support.
Easy operation with color LCD touch panel. Average, maximum, minimum, coefficient of variation, and standard deviation of impact values can be displayed and saved.
Measurement data can be saved on a PC*. (*Optional dedicated data processing software is required.)
Hammer release* is available at the touch of a button. No individual differences in hook release and improved reproducibility. (*Optional)
Instrumentation system* selectable. (*Optional. Charpy impact test and in-base method tensile impact test only)
Specimen support stand* with positioning can be selected. Specimens can be set easily and precisely. (*Option for Charpy impact test)
Safety cover* (without or with top panel) selectable (*Optional)
