Product Description

Elmendorf type tear tester for film Elmendorf tearing tester

Background

Tear resistance, also known as tear strength, stands as a pivotal mechanical characteristic defining material integrity. Originating from the fundamental necessity of withstanding tearing forces, tear resistance holds immense significance in engineering and materials science. Assessing tear resistance employs diverse methodologies, offering a versatile parameter to evaluate material durability and performance across varied conditions.

Application

The SLD-01 Elmendorf Tear Tester, named after its inventor Armin Elmendorf, precisely gauges tear resistance by measuring the average force necessary to tear a sample after initiation. Utilizing a pendulum mechanism, this tester evaluates tear strength by tearing one or multiple material sheets over a fixed distance. Such tests are indispensable in determining material suitability for applications mandating robustness and endurance.

Test Process

The test process entails creating a slit with a cutting knife, followed by the release of a pendulum mechanism to propagate the slit through the sample. The energy dissipated during tear propagation quantifies the average tearing force, crucial for assessing material tear strength accurately.

Technical Features

PLC Control and HMI Touch Screen: Industrial-grade programmable logic controller (PLC) coupled with a Human-Machine Interface (HMI) touch screen ensures precise control and user-friendly operation.
Standard Conformance: All components adhere rigorously to industry standards, guaranteeing testing consistency and reliability.
Calibration Capability: The tester includes weights for verifying and calibrating various test ranges, ensuring accurate results.
Paper-Focused Features: Catering to users dealing with paper materials, the tester allows the addition of millinewtons (mN) and tear index parameters.
Wide Test Range: Accommodates a broad spectrum of materials, ensuring versatility in testing applications.
Pneumatic Specimen Clamping: Ensures secure and uniform gripping of test materials, vital for precise and reproducible results.
Pendulum Automatic Release: Streamlines the testing process while maintaining consistency in test execution.
Data Auto Statistics and Microprinter: Automatically collects and stores test data, with the built-in microprinter enabling immediate result documentation.
RS-232 Port and Professional Software (Optional): Facilitates enhanced data analysis and reporting capabilities, further augmenting testing efficiency.
