10.2.2 The force required to prevent a stopped power operated swinging door in the last 10 degrees
of opening from moving in the direction of opening shall not exceed 30 lbf (133 N) measured 1
in. from the lock edge of the door.
10.2.3 Back check shall occur at no less than 10 degrees of the full open position.
10.2.4 Swing doors utilizing sensors or control mats shall remain open a minimum of 1.5 seconds
after loss of detection unless otherwise specified in this standard.
10.2.5 A swing door shall be adjusted so that the closing times to latch shall be the minimum values
in the following table:

For doors of other weights and widths:
T = D √W /188 where:
W = Weight of door in pounds
D = Width of door in inches
T = Closing time to latch check in seconds
10.2.6 Latch Check shall occur for swinging doors at no less than 10 degrees from closed position
and the door shall not close through the final 10 degrees in less than 1.5 seconds.
10.2.7 The force required to prevent a stopped power operated swinging door from moving in the
direction of closing shall not exceed a 30 lbf (133 N) measured 1 in. from the lock edge of the door
at any point in the closing cycle.
10.2.8 In the event of power failure, a swing door shall be capable of being opened manually with
no greater than a 30 lbf (133 N), applied 1 in. from the edge of the lock stile to open.
10.2.9 Swinging doors provided with a break away device shall require no more than 50 lbf (222
N) applied 1 in. from the edge of the locks tile to open. When the door(s) is opened in the break
out mode, powered operating components excluding spring power shall not operate the doors.
10.2.10 The opening at hinge side of swinging door shall be: a) Less than ¼ in. wide with the door
in any position, or b) At least ¾ in. wide with the door in any position. A door that does not comply
with the above is acceptable if provided with a finger guard.
11. Signage
Consistent with section 2.2.2 of ANSI Z535.4 the “signage and warnings” guidelines of A156.10
are recognized, industry specific standards that predate the adoption of Z535.4 and are not
replaced by the standards set forth therein.
11.1 All Swinging, sliding and folding doors shall be equipped with signage visible from both
sides reading “AUTOMATIC DOOR” with letters ½ in. high minimum. The sign described in figures
B-1, B-3, and B-5 shall be permitted to be used to satisfy this requirement.
