Tearing Tester (Elmendorf Method)
Machine Features:-
This tester is applicable in tearing resistance test
of films, laminated films, foils, papers, textiles and
nonwoven.
|
|
| 1. Characteristics |
Conforming to state standards and compatible with ISO and ASTM standards.
Computer controls, Windows operation system, professional software.
Rapid data gathering, high and reliable.
Pneumatic system clamps specimens and releases.
Tearing range is easy to change.
Selectable capacities of pendulum.
Assistant system of horizontal adjustment by computer.
Computer controls test, multifold units display.
Database mode storage, format is easy to change.
Easy to operate.
|
| 2. Principle |
Lift the pendulum up to certain height, enable it to have a certain potential energy, pendulum tears the specimen
while swinging down, computer calculate the decreasing energy caused by tearing.
|
| 3. Structure |
It is made up with pendulum bracket, pendulum, shaft, stationary clamp, movable clamp, augmenting weights,
knife, pendulum release system, computer, and so on.
|
| 4. Operation demo |
Horizontal adjust -> lift the pendulum, fit it -> clamp specimen -> slit the specimen -> test -> examine data
-> test over
|
