Standard for Exit Devices
Establishes requirements for exit devices and trim, automatic flush bolts, removable mullions, coordinators, and carry-open bars. Performance criteria include cycle, operational, strength, material evaluation, and security tests. Functions and types are described and numbered. Tests to evaluate decorative and protective finishes for these products are described in ANSI/BHMA A156.18 for Materials and Finishes and are required to complete certification. Tests described in this standard are performed under laboratory conditions. In actual usage, results vary because of installation, maintenance, and environmental conditions.
