These requirements cover releasing devices, such as panic hardware, fire exit hardware and exit locks, that are actuated by an actuating bar (crossbar or push pad) or actuating paddle for outward-opening doors, designed to facilitate the egress of persons from buildings in the event of panic or other emergency.

These requirements do not pertain to the fire-retardant classification of a door and releasing-device assembly.

A product that contains features, characteristics, components, materials, or systems new or different from those covered by the requirements in this standard, and that involves a risk of fire or of electric shock or injury to persons shall be evaluated using appropriate additional component and end-product requirements to maintain the level of safety as originally anticipated by the intent of this standard. A product whose features, characteristics, components, materials, or systems conflict with specific requirements or provisions of this standard does not comply with this standard. Revision of requirements shall be proposed and adopted in conformance with the methods employed for development, revision, and implementation of this standard.

Fire Exit Hardware shall additionally be evaluated to the Standard for Safety for Positive Pressure Fire Tests of Door Assemblies, UL 10C.
