Yasuda Seiki - No.315 - Elmendorf Tearing Resistance Tester

 

The Elmendorf Tearing Resistance Tester is a specialized instrument used to measure the tear resistance of materials such as paper, textiles, plastic films, and other sheet materials. It is named after Dr. Armin Elmendorf, who invented the device ;

An Elmendorf Type Tearing Resistance Tester is a precision instrument used to measure the tear strength or tear resistance of a wide range of sheet materials, including paper, paperboard, plastic films, and textiles. The test is commonly known as the Elmendorf tear test.

Yasuda Seiki - No.315 - Elmendorf Tearing Resistance Tester

The Elmendorf Tester quantifies the force required to continue a tear in a material once the tear has been initiated. This is known as tearing resistance, typically measured in units like:
-> mN (millinewtons)
-> gf (gram-force)
-> N (newtons)
-> lbf (pound-force)

Aplication Elmendorf testers are vital for quality control and material research in various industries. The test provides a quantitative measure of a material's durability and ability to withstand tearing forces, which is crucial for:

Paper and Packaging : Ensuring the tear resistance of paper, cardboard, and other packaging materials to prevent tearing during handling and transportation.

Plastics and Films : Testing the strength of plastic films used in packaging, construction, and agriculture.

Textiles and Fabrics : Assessing the tear strength of fabrics for clothing, upholstery, and technical textiles like those used in parachutes and protective gear.

Yasuda Seiki - No.315 - Elmendorf Tearing Resistance Tester

The Elmendorf tear test is standardized by several national and international organizations to ensure consistent and comparable results. Some of the most common standards include:

ASTM D1424: Standard Test Method for Tearing Strength of Fabrics by Falling-Pendulum Type (Elmendorf) Apparatus.

ASTM D1922: Standard Test Method for Propagation Tear Resistance of Plastic Film and Thin Sheeting by Pendulum Method.

ISO 1974: Paper - Determination of tearing resistance - Elmendorf method.

TAPPI T414: Internal Tearing Resistance of Paper (Elmendorf-Type Method).

=============================================== 

 The tester operates on the principle of a bi-directional pendulum weighing system. Here's a step-by-step breakdown of the testing process:

A rectangular specimen (typically 1.5 inches wide by 2.75 inches long) is clamped vertically at one end.

The free end of the specimen is positioned between a pair of rollers attached to a rotating disk.

The disk rotates at a constant speed, causing the rollers to push against the specimen and deflect it from its vertical position.

As the specimen bends, it causes the pendulum to deflect from its center. The pendulum applies an increasing torque to the specimen.

When the specimen is deflected to a predetermined angle (usually 7.5° or 15°), the bending moment is measured. The test is performed in both the left and right directions, and the readings are averaged to determine the material's stiffness.

The result is a quantitative value of the material's resistance to bending.
