TEAR RESISTANCE

Video 01:Tear Strength Single Tear Method

The most common method for tear testing involves die-cutting a material sample and introducing a point of rupture. The force required to tear the material is then measured and recorded as the tear strength. This testing can also be performed at various temperatures to measure the material’s resistance accurately.
The JIS K 6252 method evaluates the tear strength of rubber parts, while the NISSAN—NES M0007 method measures the tear resistance of small (Delft) pieces. Both methods involve introducing a point of rupture in the specimen and measuring the force required to tear the material. The results of these tests are then used to determine the material’s tear strength.
