This Standard describes a method for the determination of the tear resistance of flexible plastic film and sheeting at very low rates of loading, 51 mm/min. The test is designed to measure the force to initiate tearing. The specimen geometry of this method produces a stress concentration in a small area of the specimen. The maximum stress, usually found near the outset of tearing, is recorded as the tear resistance in newtons.
