2010 Americans with Disabilities Act Standards (ADAS) section 404.2.9 Door and Gate Opening Force: Fire doors shall have a minimum opening force allowable by the appropriate Administrative Authority. The force for pushing or pulling open a door or gate other than fire doors shall be as follows: 1. Interior hinged doors and gates: 5 pounds maximum. 2. Sliding or folding doors: 5 pounds maximum. These forces do not apply to the force required to retract latch bolts or disengage other devices that hold the door or gate in a closed position. Advisory 404.2.9 Door and Gate Opening Force. The maximum force pertains to the continuous application of force necessary to fully open a door, not the initial force needed to overcome the inertia of the door. It does not apply to the force required to retract bolts or to disengage other devices used to keep the door in a closed position. OPERATING INSTRUCTIONS : 1. Set the top (small) o-ring located on the plunger rod on zero, down against the instrument's flange; or set the o-ring on the desired force. 2. Holding the instrument firmly, press slowly against the door at a point approximately handle-high, and 30 inches away from the door's hinges. 3. Read the amount of force required to open the door on the plunger scale closest to the bottom of the small o-ring. A must have for determining ADA compliance!
