A Complete Guide to Tearing Strength and Sizing Tester

The material's tearing capability is a key aspect in determining its quality. The material tear resistance test can assist you in determining whether or not your product can withstand the tearing force. The UEC tearing strength tester is a prominent piece of testing equipment for assessing a material's tearing strength. This laboratory testing instrument is appropriate for a wide range of industries, including textiles, plastic films, and similar materials. This post will provide you with basic information on ripping strength testers and how to easily prepare testing samples using this laboratory testing equipment.

This accurate lab testing equipment enables you to deliver your products without error. The tearing force may be easily estimated using scale reading and pendulum capacity. A conventional formula will calculate the average ripping force after slicing the specimen perpendicular to the warp direction. Here is a list of the tester's features:

• It features a strong, high-quality structure with a corrosion-resistant main body and a falling pendulum to cover various measurement ranges.

• Easy one-handed operation.

• Extremely accurate testing results utilizing several pendulum weights.

• Calibration weights are assigned in advance.

• A falling-pendulum mechanism

The tearing strength tester is one of UEC's most capable and best-selling testing tools, assisting you in the quality assurance process. This UEC sample testing machine helps to reduce mistakes by delivering an exact result of rip resistance strength. In this testing apparatus, the pendulum pivots on anti-friction ball bearings on a vertical bracket fastened to a robust iron base in this testing apparatus. The rectangular test span is held between two jaws, one on the pen vertical dagger, and the jaw clamps are positioned so that their gripping faces are aligned. re-aligned with each other. The Vertical Arm also has an adjustable knife. It is passioned between the two Jaws to create the first slit in the test specimen. Lifting a brake release lever a result of this activity, the test specimen rips. a result of this activity. The ripping strength is shown by a pointer on a calibrated scale attached to the pendulum. The tester comes with a set of calibrated check weights for verifying the scale's capabilities of 1600, 3200, and 6400 grams.

Any packing material comprised of paper or pulp has the propensity to absorb water. This weakens the packing and has an impact on the items packed within. It is critical to test the water absorption and retention capacity of any material before utilizing it for packaging. The Cob sizing tester value is calculated to evaluate the material's ability to absorb water. This cobb value must be maintained to retain the paper's quality and Fullbacks. The test involves measuring the amount of water absorbed in a certain amount of time using non-bibulous paper with a thickness of 0.1 mm.

How Does the Cobb Sizing Test Work?

• The Cob sizing tester features a spherical steel platform with a cork-filled steel cylinder at the bottom.

•  A sample of the substance to be evaluated is cut out. Make sure the sample is larger in size than the steel platform. Weigh it again to the closest 0.1 gram.

•  Place a cork sheet on the platform, followed by the sample. The goal of having a cork sheet is to prevent sample sliding.

• Tightly clamp the sample. Remember to put the cork ring at the bottom of the cylinder. This assures that no water leaks occur throughout the test. This cork is waterproof and has no effect on the sample's qualities.

•  If there is any leakage, reject the test and sample and restart.

COBB Value Calculation Formula

• Cobb Value = sample weight after testing - sample weight before testing
