OPEN DOORS
4.1
Opening Time
4.1.1
Doors shall be field adjusted so that opening time to back check or 80
degrees, which ever occurs first, shall be 3 seconds or longer as required
in Table 1. Back check shall not occur before 60 degrees opening.
4.1.2
Total opening time to fully open shall be 4 seconds or longer.
4.2

seconds unless a sensing device is used to hold the door open.
4.4
The force required to prevent a stopped door from opening or closing shall
not exceed a 15 lbf (67 N) applied 1 in (25 mm) from the latch edge of the
door at any point in the opening or closing cycle.
4.5
The kinetic energy of a door in motion shall not exceed 1.25 lbf-ft (1.69
Nm). Table 1 provides speed settings for various widths and weights of

4.6
In the event of power failure to the operator, doors shall open with a
manual force not to exceed a 15 lbf (67 N) or torque of 40 lbf-in (4.5 Nm)
to release a latch, a 30 lbf (133 N) to set the door in motion, and a 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.
