scope:

GENERAL

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.

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 design installations.

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.

Required dimensions are expressed in US units first. The SI (metric) equivalents given in parentheses are approximate.

American National Standards referenced in A156.10 are available from the American National Standards Institute, 11 West 42nd Street, New York, NY 10036. ASTM Standards referenced in A156.10 are available from ASTM, 100 Barr Harbor Dr., West Conshohocken, PA 19428-2959 (also see Appendix C).

Tolerances. Where only minus tolerances are given, the dimensions are permitted to be exceeded at the option of the manufacturers. All values that do not carry specific tolerances or are not marked maximum or minimum shall have the following tolerances: Linear dimensions shall be +/- 1/16 inch (1.6mm). Pounds or pound force shall be +/- 2%. Degrees opening shall be +/- 2 degrees. Electrical measurements shall be +/- 2%.

Tests described in this standard are performed under laboratory conditions. In actual usage, results vary because of installation,
