Electrified locking systems are covered in ANSI/BHMA standard A156.25, which encompasses locking devices, input devices, controlling devices, and power supplies. Delayed egress locks are covered in ANSI/BHMA 156.24
Hinges. Finally, hinges are a surprising product often featuring electricity. Since hinges involve minimal movement, they have proven a useful storage vehicle to thread electrical wiring from the frame to the door.
Expanding the Specifications
When BHMA began specifying standards in 1969, the focus was not initially on electrified builders hardware. Since then, standards testing has undergone constant updating to keep pace with evolving technology.
Covering electronics wasn’t just about creating new standards, but modifying old ones. One of the first standards for cylinders – A156.5 – had to be updated several times to encompass evolving electronic cylinders. In the last several months alone, BHMA has amended three standards for electrified hardware.
Electronic hardware devices have added components and therefore must be tested with additional features in mind – such as the safety and functionality of electrical equipment. They require additional electromechanical trials above and beyond the strictly mechanical testing for ordinary locking devices. Like all BHMA products, electronic architectural hardware must endure a battery of tests, including those for:
- door slams
- electrical functionality and durability
- environmental salt spray
- rain and dust
- overcurrent protection
- dielectric voltage
- inductive kickback
While electromagnetic locks, electric strikes, electrified keys, and other products can be some of the most difficult to specify, Builders Hardware Manufacturers Association ensures its technical committees are always up-to-date on products, using members as an important resource.

Product grades are defined by performance benchmarks, with Grade 1 being the highest level of performance.
