General Information - A156.10*
Compliance with American National Standard A156.10 and A156.19 is intended to reduce the chance of injury to pedestrians and wheeled traffic. Most all local codes, such as BOCA, require compliance with A156.10 if automatic doors or door operators are used. ANSI states that these are suggested standards, but compliance is required when local building codes incorporate A156.10. Eastern Door Service has provided you with our general overview and interpretation of A156.10. You should obtain and thoroughly read an actual copy of A156.10 - 2005 available from the American National Standard Institute, 1430 Broadway, New York, NY 10018.  They are also available for purchase online at TechStreet™ for a nominal charge.

  • Safety control mats if used must be at least as wide as the door frame opening less 5" (127 mm) on each side. The active area of the safety mat must not be more than 5" (127 mm) from the door's jambs.
  • Matless safety sensing devices must have a detection zone extending at least 5" (127 mm) past the edge of a fully open door.

  • If matless sensing devices are used for both actuation and safety, a 6" (152 mm) maximum inactive area is permitted centered in the door's threshold, but must include a) safety mat extending a minimum of 5" (127 mm) through the threshold measured from the face of the door opposite the swing side; or b) safety sensing device that will prevent a fully open door from closing on a person; or c) the door shall remain open for a minimum of 4 seconds, after the door open signal is removed.

 

Guide Rails- Swing Doors

  • Two guide rails must be installed on the swing side of each door, unless a wall or other separation device is used in place of a guide rail.
  • The guide rails must extended from the face of the door jamb a distance at least equivalent to the widest door leaf width.
  • Guide rails used on swing doors for two-way traffic must extend from the face of the door jamb to at least 60" (1524 mm) past the edge of the widest door leaf in the full open position.
  • Guide rails must be at least 30" (762 mm) high.
  • Guide rails must have a panel or a divider bar.
  • Not more than a 6" (152 mm) gap is allowed between the rail and the leading edge of the door's travel arc.
  • Not more than a 6" (152 mm) or less than a 2" (51 mm) gap is allowed between the face of a fully opened door and the guide rail.
  • Gaps between the door's jamb and a free standing rail must not exceed 2" (51 mm).

 

Decals and Markings - Swing Doors

  • A decal or sign with an arrow must be visible from the approach side of the door. The arrow sign must be at least 6" (152 mm) in diameter, with a green circle surrounding a black arrow with a white background.

Entrapment Protection - Swinging Doors

  • Not more than 40 lbf (180 N) shall be required to prevent a stopped swinging door from moving to the closed position. Forces must be measured 1" (25 mm) from the latch edge of the door panel.
  • A swinging door must not open to back check (not less than 80 degrees) in less than 1.5 seconds.
  • Not more than 40 lbf (180 N) shall be required to prevent a stopped swinging door from moving, during its last 10 degrees of opening. Forces must be measured 1" (25 mm) from the latch edge of the door panel.
  • A swinging door must not complete travel through its last 10 degrees of opening in less than 1.5 seconds.
  • Swinging doors must not close to latch check (10 degrees) in less than 2.3 seconds for a 36" (915 mm) door weighing up to 140 lbs. (64 Kg), 2.7 seconds for a 42" (1067) door weighing up to 150 lbs. (68 Kg), or 3.2 seconds for a 48" (1219) door weighing up to 160 lbs. (73 Kg). For other door sizes multiply the square root of the door's weight in pounds by the width of the door in inches. Divide the total by 188 and you will get minimum closing time in seconds.
  • Automatic swinging doors must be provided with fingerguards preventing digit entrapment between the back edge of the door and the door's jamb.
  • Manual opening force for automatic swing doors must not exceed 50 lbs. (222 N), measured 1" (26 mm) from the latch edge of the door.
  • Inswinging automatic doors used for emergency egress must swing toward the direction of egress with not more than 50 lbs. (222 N), measured 1" (26 mm) from the latch edge of the door. The door's operator, excluding spring power, must be disabled when the door is in the panic breakout mode.

 

Entrapment Protection - Sliding Doors

  • Not more than 30 lbf (133 N) shall be required to prevent a stopped sliding door from moving to the closed position, during any point of its closing travel.
  • Closing speed to latch check (not less than 2" (51 mm) from fully closed) must not exceed 1 foot per second for doors weighing up to 160 lbs. (71 Kg) per door leaf. For doors over 160 lbs. (71 Kg), maximum velocity in ft/second is equal to the square root of 161 divided by the weight of the door in pounds, as illustrated below.
  • Sliding doors used for emergency egress must swing out toward the direction of egress with not more than 50 lbs. (222 N), measured 1" (26 mm) from the latch edge of the door.
  • If the door's sliding panels and stationary sidelights breakout for emergency egress, the door's operator must be disabled when the door is in the panic breakout mode. If the sliding doors breakout and the stationary sidelights do not, a spring closing device may be provided in lieu of or in addition to the disabling of the door's operator.
