BHMA Announces Revolving Door Standard; Updates Low-Energy Door Standard

The Builders Hardware Manufacturers Association (BHMA) has published the new standard ANSI/BHMA A156.27-2003 American National Standard for Power and Manual Operated Revolving Pedestrian Doors. In addition, the association has revised and updated ANSI/BHMA A256.19-2002 American National Standard for Power Assist and Low Energy Power-Operated Doors.

BHMA says the new standard is the first to concentrate entirely on requirements for revolving doors. The 22-page document includes numerous definitions and 11 illustrations. Topics covered include maximum allowable RPMs, clearances, starting forces, emergency stop switches and activation devices.

The updated low-energy door standard, ANSI/BHMA A156.19-2002, is a revision of A156.19, which applies to power-assist doors, low-energy, power-operated doors or low-energy power open doors for pedestrian use, and some small vehicular use. The standard includes provisions intended to reduce the chance of user injury or entrapment and addresses many requirements not provided for in ANSI/BHMA A156.10 for Power Operated Pedestrian Doors.
