ASTM D256 Plastics Izod and Charpy Pendulum Impact Tester with LCD
for Non Metal
Brief Introduction:
iqualitrol XJC Pendulum Impact Tester is used to test the
anti-impact intensity both in izod and charpy of engineering
plastics, glass-steel, ceramics, casting stone, plastic wiring,
insulating material, plastic pipe material and other non –metallic
materials.
iqualitrol XJC Pendulum Impact Tester equips with electronic
controlling system which is much easier operated and the test
result is calculated automatically.
Izod impact testing is an ASTM standard method of determining the
impact resistance of materials. A pivoting arm is raised to a
specific height (constant potential energy) and then released. The
arm swings down hitting a notchedsample, breaking the specimen.
The energy absorbed by the sample is calculated from the height the
arm swings to after hitting the sample. A notched sample is
generally used to determine impact energy and notch sensitivity.
The Charpy impact test, also known as the Charpy V-notch test, is a
standardized high strain-rate test which determines the amount of
energy absorbed by a material during fracture. This absorbed energy
is a measure of a given material's notch toughness and acts as a
tool to study temperature-dependent ductile-brittle transition. It
is widely applied in industry, since it is easy to prepare and
conduct and results can be obtained quickly and cheaply. A
disadvantage is that some results are only comparative.
