What is a Tearing Strength Tester and Its Purpose?

Responsive image

In the textile industry, the strength of materials such as fabrics, plastic films, etc. is considered to be more vital in determining its quality. These types of materials will get easily torn out with a small amount of tearing force. Thus, to know the tearing resistance of these materials, you can easily make use of a tearing strength tester. This is one of the highest quality testing instruments from Testronix that will help you to determine the tearing strength of different materials. Let’s get started with the brief information about this authentic testing instrument.

Introduction about tearing strength tester

The tearing strength tester from Testronix Testing Instruments is one of the widely used testing equipment that will help you determine the tearing strength of various materials. The tearing strength will help you to calculate the tensile force that will tear your specimen. This brilliant testing machine will measure the tearing strength of materials with precision. It has been made in accordance with various laboratory testing standards that include ASTM D1424-09 (2013), ASTM D1776, ASTM D624-00(2012), ASTM D689.

This testing instrument has a high-quality rugged structure with a corrosion-resistant main body. This falling pendulum-type testing instrument will easily help you in the easy determination of tearing strength. You can perform hassle-free testing operations single-handed with the help of this tearing strength tester.

It has inbuilt calibration weights and a strong gripping fixture for holding the test samples accurately. Here we have listed some of the amazing features you will get with this lab testing instrument.

Features of Testronix tearing strength tester

The tearing strength of the materials is very important in determining their quality. This highly advanced testing tool from Testronix comes with an adjustable knife that is mounted on the vertical arm. This testing instrument is centered between the two Jaws for making the initial slit in the test specimen. The pendulum is released by lifting a brake release lever. This action causes the test specimen to tear. The tearing strength is indicated on a calibrated scale fitted on the pendulum by a pointer.

Here are some amazing features you will get with the use of a tearing strength tester:

  • The instrument consists of a falling pendulum to cover various measuring ranges.
  • It is provided with cutting templates, a cutting knife, and a sample cutting board for preparing a specimen for the test.
  • The tearing test parameters include tearing strength, peak load, and median load.
  • The test method is used for determining tear strength involves imparting a cut in the center.
  • There is an opposing tail, also called the tongue, which is clamped in the instrument and pulled apart.
  • Highly accurate testing results will be shown.

Technical specifications of tearing strength tester

  • The capacity of the Tearing: 1600 g (can be increased to 3200 g or 6400 g by adding augmenting weights
  • Tearing Distance : 43 +/0.15mm
  • Reading of Scale : 0 to 100% Range
  • Range of Weights: 1600, 3200, 6400 gms
  • Scale Reading: 0 to 100% of range
  • Accuracy: ± 2% within the entire range.
  • Least count of scale: 1%

These are the technical specifications of this testing instrument designed by the experts at Testronix. If you wish to maintain this testing instrument then you can check the friction of the pendulum and pointer assembly periodically. When you conduct this tearing strength test before and after one month of non-use, then checking friction will be a necessity. By checking the friction of the pendulum from time to time, you can easily make sure that your testing instrument will run for a longer time.
