ASTM D1004
ASTM D1004-13 covers the determination of tear strength or tear resistance of flexible plastic film and sheeting. The site of tear is initiated by a high stress concentration caused by the 90° angle in the specimen.

How running torque is measured
Running torque is typically measured using precision torque sensors mounted within a controlled test stand. The component under test is rotated at a defined speed, and torque is measured continuously during motion.
