Tej Engineers - Impact Testers

Generally Plastics Films are used for 'Packaging Application', and undergo wear & tear. Hence study of 'Impact' Resistance is established to evaluate the quality and mechanical property of the film.

This method covers the determination of the energy that causes Plastics Film to rupture under specific conditions of impact of a Free Falling Dart (load). This energy is expressed in terms of weight (mass) of the missile falling from a specified height which would result in %age specimen's failure tested.

Izod impact strength test is an ASTM D256 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 notched sample, 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 test is similar to the Charpy impact test but uses a different arrangement of the specimen under test.
The Izod impact test differs from the Charpy impact test in that the sample is held in a cantilevered beam configuration as opposed to a three-point bending configuration.

Impact Tester is used for PVC pipes, UPVC pipes CPVC pipes Ect
