Elmendorf Yırtma Test CihazıTESTING MACHINES INC.
The Elmendorf Tear Tester is an automated tear tester equipped with an optical encoder for measuring the angular position of the pendulum during tearing and converting this measurement to tear units. A large, full-color touchscreen display with intuitive, easy-to-use software provides a revolutionary new approach to testing and data review.
The Spencer Impact method is based on ASTM D 3420. An attachment to the Elmendorf Tear Tester is mounted on the top of the instrument and measures the puncture impact resistance of a plastic film sheet or other related sheet-like material. The fixture consists of a probe mounted onto the end of the Elmendorf pendulum and an air-operated clamp used to secure the film sample. The unit measures the resistance to impact/puncture as the probe penetrates a sheet of plastic film. Both Elmendorf Tear and Spencer Impact measurements can be performed on one instrument.
