Rubber Tear Resistance Test Machine

ASTM D624 and ISO 34-1 are similar tear strength test methods for rubber test samples. The test results in the measurement of a materials resistance to tearing. Tear strength can also be used to monitor material anisotropy of a material. ASTM D624 and ISO 34-1 both define tear strength as the measurement of force required to tear a test sample divided by specimen thickness. Testing is performed by pulling specimens apart using a universal test machine equipped with tensile testing grips. An application engineer can assist in the selection of the best grip and jaw face for rubber tests. Pneumatic air grips with serrated or rubber coated faces are common. A constant gripping force can prevent specimen slippage when specimens elongate. Self-tightening grips, such as roller grips, are also adequate for rubber tests.
