ANSI/BHMA A156.27-2019: Standard for Revolving Doors

ANSI/BHMA A156.27-2019: Power And Manual Operated Revolving Pedestrian Doors

The American National Standard for revolving doors, ANSI/BHMA A156.27-2019: Power And Manual Operated Revolving Pedestrian Doors, helps make building entrances efficient and safe.

For many, revolving doors represent both the beginning and conclusion of the average work day. These doors often serve the boundaries between the haste of corporate careers and the alacrity of the outside world. The transition between the two is seamless: just push and walk through.

The first official revolving door was invented in the late 19th Century by Theophilus von Kannel. It was designed to be a more efficient alternative to the traditional swinging door and reduce stack effect pressure in buildings. Revolving door design limits the escape of air and reduces drafts, curtailing heating and cooling expenses. Ingress and egress are expedited. Noise pollution from the outside world is minimized. These benefits are why many office buildings, airports, hotels, and other structures choose to feature revolving doors as their main entrances.

The technology behind revolving doors has vastly improved over time. Some have sensors or encapsulate facial recognition and other security features. As technology evolves and adapts, the procedures with which we handle it must be coordinated. To assure that public safety is preserved and properly aligned with these improvements and that efficiency is maintained, ANSI/BHMA A156.27-2019 has been revised.

ANSI/BHMA A156.27-2019 is applicable to an array of revolving door types. Specifically, this standard applies to power-operated revolving doors that rotate automatically when approached by pedestrians, some small vehicular use, and manual type revolving doors for pedestrians.

ANSI/BHMA A156.27-2019 includes provisions to reduce the likelihood of user injury and entrapment. The standard accomplishes this by providing the maximum and minimum dimensions for various components of revolving doors. It also provides users with data such as proper clearance, obstruction force, acceptable door speed among a plenitude of other crucial safety measurements and procedures all in compliance with industry standards.

In listing the proper measurements and procedures in the lexicon of the installation of revolving doors, ANSI/BHMA A156.27-2019 provides for safe, efficient, and cost-effective experience. ANSI/BHMA A156.27-2019 revises the 2011 version of the same American National Standard. This revision introduces the parameters around presence sensor monitoring.

Please note that ANSI/BHMA A156.27-2019 does not attempt to assess any factors that exist with respect to custom installations.
