Tear Tester SLD-01

SLD-01 tear tester is a standard test for determining the tear resistance which is named after its inventor, Armin Elmendorf. The Elmendorf test determines the average force required in grams or mN to tear a sample  after the tear has been started. In conducting the test, one or more sheets are torn through a fixed distance by means of a pendulum. The effort expended in tearing is measured by the loss of potential energy of the pendulum.

Application

Tear resistance is one of the important mechanical parameters of material.  Tear resistance (or tear strength) is a measure of how well a material can withstand the effects of tearing. It is a useful engineering measurement for a wide variety of materials by many different test methods.

Test Principle

Acting by gravity, the pendulum is released to propagate the slit through the remaining 43mm. The energy loss by the pendulum is used to calculate an average tearing force.

Technical Features

SLD-01 tear tester has below technical features. It uses PLC control and HMI (human-machine interface) touch screen. The industrial class design ensures its stability and long service life.  

1. PLC technology and human-machine interface. 
2. Wide test range for different materials
3. Pneumatic specimen clamping 
4. Pendulum automatic release 
5. Data auto statistics, storage 
6. Microprinter 
7. RS 232 port and professional software(optional)
