ASTM D Tear Resistance (Graves Tear) of Plastic Film and Sheeting – Instron
The specimen geometry and speed of testing in this test method are controlled to produce tearing in a small area of stress concentration at rates far below those usually encountered in service.
The maximum stress, usually found near the onset of tearing, is recorded as the tear resistance in newtons or pounds-force. ASTM D covers the determination of tear strength d10004 tear resistance of flexible plastic film and sheeting.
