In the textile industry, the strength of materials such as fabrics and plastic films is the decisive factor in quality. These types of materials have a low tear force and tear easily. Therefore, a tearing strength tester can be easily used to determine the tear strength of these materials.
Let’s start with some quick information about this authentic tearing strength tester.
Introduction of Tearing Strength Tester
A tear strength tester is one of the widely used testing equipment that can be used to measure the tear strength of various materials. Tear Strength helps calculate the tensile force to tear a sample. The tearing strength tester is manufactured according to various laboratory test standards such as ASTM D1424-09 (2013), ASTM D1776, ASTM D624-00 (2012), and ASTM D689.
These instruments are high-quality testers with a robust body structure that excels in corrosion resistance. The drop pendulum tester helps you measure tearing strength easily. With this tear strength tester, you can easily perform the test.
Built-in calibration weights and strong gripping devices hold test samples precisely. Here are just a few of the amazing features you’ll get with this lab tester.
Features of Tear Strength Tester
A material’s tear resistance is very important to its quality. This test fixture is cantered between two jaws to create the first slot in the test sample. The pendulum is released by lifting the brake release lever. This action leads to the tearing of the specimen. The breaking strength is displayed on a calibrated scale attached to the pendulum by a pointer. With a tear strength tester, you get unique features such as:
The instrument consists of a falling pendulum covering different measuring ranges.
- A cutting template, cutting knife, and sample cutting board is included to prepare samples for testing.
- Tear test parameters include tear strength, peak load, and average load
- The test procedure for determining tear strength involves cutting in the middle
- The opposite tail, also called the tongue, is pinched by the instrument and pulled away
- Displays highly accurate test results
Specification of Tearing Strength Tester
- Tearing Capacity: 1600g (can be increased to 3200g or 6400g by adding auxiliary weights)
- Tearing Distance: 43±0.15mm
- How to read the scale: 0 to 100% range
Weight range: 1600, 3200, 6400g
- Scale reading: 0 to 100% of the range
- Accuracy: ± 2% over the range
- Minimum scale: 1%
The tear strength of a material is one of the important properties that can be used to briefly describe the tear strength of the material. It generally involves the force required to shred the material and maintain the fracture until the material breaks. The higher the tear resistance of the textile foil, the stronger the material is considered. Therefore, materials with high tear strength are considered the best and safest for delivery to customers.
Paper Tear Strength Tester is an analogy display designed to determine the average force required to propagate a tear tongue tear from a cut in paper, cardboard, plastic, nonwovens, and fabric when properly configured A falling pendulum paper tearing tester with ASTM-compliant paper tear testers are suitable for most materials, including woven fabrics, multi-layer blankets, piles, blankets, and airbag fabrics, but should the fabric tear along the direction of the force applied during the test. It is provided that there are no Fabrics that may be untreated, heavily sized, coated, resin-treated, or otherwise treated. This test method uses a falling pendulum apparatus (Elmendorf) to measure the average force required to propagate a single tear through a cut in a nonwoven.
Thus the tearing strength tester is not only used in the fabric industry but equally an important part of other industries. The paper and packaging testing instruments include this machine to test the resistance of papers.
