Door Locking Standards

Door standards from the Builders Hardware Manufacturers Association address a range of features and characteristics of doors. Covering door controls, hanging, locking, trimming, power assist, and other standards, this set comes together to provide a comprehensive toolkit for manufacturers to create hardware that designers and users can depend on with a focus on reliability and interoperability. These standards are related to a wide variety of locking mechanisms for different doors.

ANSI/BHMA A156.2-2017

Bored and Preassembled Locks and Latches

This Standard establishes performance requirements for bored and preassembled locks and latches, and includes dimensional criteria, operational tests, strength tests, cycle tests, security tests, material evaluation tests, and finish tests.

ANSI/BHMA A156.25-2018

Electrified Locking Devices

Electrified locking systems are usually comprised of four functional components: locking devices, input devices, controlling devices, and power supplies. This Standard establishes requirements for the locking devices, whose mechanical aspects are described in the applicable BHMA product Standards; in addition, where the input or controlling device or both are an integral part of the locking device, they shall also be tested with the locking device covered by this Standard. This Standard includes requirements for cyclical, security, operational, strength, and environmental tests for these products.
