EUROLAB, with its state-of-the-art accredited laboratories and expert team, offers precise and rapid testing services within the scope of EN ISO 4674-2 testing. This standard specifies a method for determining tear resistance based on the effect of active force applied to a notched test piece.
Testing can be performed on:
The results obtained with this method are not comparable to those obtained with methods involving constant tear rate.
Tearing is one of the most common ways to destroy many thin materials such as paper, coated or uncoated textiles, plastic films and leather. Therefore, it is very important to know the resistance of these materials to such behavior. In practice, tearing can be caused by many different situations; This is why numerous testing methods have been developed to predict the behavior of materials in various situations.
The standard outlines the equipment and apparatus required to perform the test. This includes a test sample, a cutting device to make the initial cut, a pendulum impact apparatus, and a measuring system to measure the energy absorbed during the test.
EN ISO 4674-2 provides detailed instructions for preparing the test specimen, making the initial cut and performing the tear resistance test using the ballistic pendulum method. The standard specifies the test conditions, including the angle of release of the pendulum and other relevant parameters.
Tear resistance is a critical property of coated fabrics because it affects the material's performance in applications where it may be subjected to tearing forces. Understanding tear resistance is important for manufacturers and users to ensure the material is suitable for its intended use in protective clothing, industrial applications or other areas.
