ANSI/BHMA A156.30-2007


American National Standard for High Security CylindersBuilders Hardware Manufacturers Association / 21-Dec-2007 / 19 pages

1.1This standard includes security performance based requirements for both mechanical and electrified high security cylinders. For the purpose of this standard, High Security Cylinder includes mechanical lock cylinders, electromechanical cylinders, and the electronic lock sub assemblies that are analogous to the cylinder assemblies. Cylinders include their keys or electronic credentials; their detainers (mechanical pins, levers, discs) or electronic control device; and their cylinder tailpiece or cam or electronic output port.
1.2Tests described in this Standard are performed under laboratory conditions. In actual usage, results vary because of installation, maintenance and environmental conditions.
1.3Levels and Grades
1.3.1 Levels Manufacturers shall indicate the high security level of their cylinders. Cylinders shall meet all the tests for their level listing, indicated in accordance with Section 8. Levels indicate special security features and are separate from Grades. A lockset mated with a cylinder having no Grade listing, even though the cylinder has a high security level is considered ungraded.
1.3.2 Grades To obtain cylinder Grade listings, and for the mating lock to retain its Grade listing, cylinders must be tested in accordance with ANSI/BHMA A156.5 for Auxiliary Locks and Associated Products. Assemblies take the grade of the lowest graded component. Electrified products shall also meet the requirements of A156.25 for Electrified Locking Devices to obtain a grade listing.
