Understanding ASTM D689 ASTM D689 defines a standardized method to measure the force required to tear paper in a direction perpendicular to the sheet plane after a tear has been initiated. The test relies on an Elmendorf pendulum mechanism, which converts potential energy loss into a measurable tearing force.
