ISO 34-1 measures tear strength test methods for rubber test samples. The test results in measurement of a materials resistance to tearing. Tear strength can also be used to monitor material anisotropy of a material. 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. Trouser, angle and crescent test pieces
Before conducting BS ISO 34-1, it is important to read the entire specification. Standards can be obtained from appropriate standard authorities.
