REQUIREMENTS FOR POWER OPERATED DOORS
The following texts are excerpts from American National Standard for power-operated doors.
Please refer to the full standard if necessary.
20.1.1
Activation
The operator shall be activated by a knowing act.
20.1.2
Opening
Doors shall open from closed to back check, or 80 degrees which ever occurs first, in 3 seconds
or longer as required in Table I. Backcheck shall not occur before 60 degrees opening. Total
opening time to 90 degrees shall be as in Table II. If the door opens more than 90 degrees, it
shall continue at the same rate as backcheck speed. When powered open, the door shall remain
at the open position for not less than 5 seconds.
20.1.3
Closing
Doors shall close from 90 degrees to 10 degrees in 3 seconds or longer as required in Table I.
Doors shall close from 10 degrees to fully closed in not less than 1.5 seconds.
20.1.4
Force and Kinetic Energy
The force required to prevent a stopped door from opening or closing shall not exceed 15 lbf
(67 N) measured 1 in (25 mm) from the latch edge of the door at any point during opening or
closing.
The kinetic energy of a door in motion shall not exceed 1.25 lbf-ft (1.69 Nm). Table I provides
minimum times for various widths and weights of doors for obtaining results complying with
this kinetic energy.
Doors shall open with a manual force not to exceed 15 lbf (67 N) to release a latch, if equipped
with a latch, 30 lbf (133 N) to set the door in motion, and 15 lbf (67 N) to fully open the door.
The forces shall be applied at 1" (25 mm) from the latch edge of the door.
Table I
Minimum Opening Time to Back Check or 80 degrees, which ever occurs first, and the Minimum
Closing Time from 90 degrees to Latch Check or 10 degrees.
