grams of force X 16 ------------------- = grams required to tear one sheet, number of sheetswhere 16 is the conversion factor, unless an augmenting weight is added to the pendulum, in which case the conversion factor becomes 32.

The Elmendorf tester consists essentially of a stationary clamp, a movable clamp carried on a pendulum formed by a sector of a circle free to swing on a ball bearing, a knife mounted on a stationary post for starting the tear, means for leveling the instrument, means for holding the pendulum in a raised position and for releasing it instantaneously, and means for registering the maximum arc through which the pendulum swings when released.
