1.1 Scope Requirements in this Standard apply to power operated doors for pedestrian use which
open automatically when approached by pedestrians and some small vehicular traffic or by a knowing
act. Included are provisions to reduce the chance of user injury or entrapment. Power operated doors
for industrial or trained traffic are not covered in this Standard.
1.1.1 Where this Standard contains specifications relating to minimum or maximum dimensions of
various components of power operated doors for pedestrian use and some small vehicular traffic, such
dimensions are included to provide user protection for what are, in the industry, standard application
conditions. This Standard does not apply to custom installations.
1.2 This Standard does not apply to power assist and low energy power operated doors. Refer to
ANSI/BHMA A156.19 for Power Assist and Low Energy Power Operated Doors.
1.3 Required dimensions are expressed in US units first; approximate metric equivalents follow in

1.5 Tolerances Where only minus tolerances are given, the dimensions are permitted to be
exceeded at the option of the manufacturers. All values which do not carry specific tolerances or are
not marked maximum or minimum shall have the following tolerances: Linear dimensions shall be +
1/16 in (1.6 mm). Pounds or pound force shall be + 2%. Degrees opening shall be + 2 degrees.
Electrical measurements shall be + 2%.
1.6 Tests described in this standard are performed under laboratory conditions. Measurements shall
be taken under neutral air pressure conditions. In actual usage, results vary because of installation,
maintenance and environmental conditions.
1.7 Doors used as fire doors or smoke barriers have additional requirements not covered in this
1.8 Where required by the authority having jurisdiction, products meeting the requirements of this
