The Builders Hardware Manufacturers Association (BHMA) Certification Program was developed as a means for producers of builders hardware to indicate compliance with American National Standards sponsored by BHMA. Participating manufacturers certify compliance with thestandards based on a continuing program of passing the prescribed tests. Third party testing is performed by a Nationally Recognized Test Laboratory. The program is open to all manufacturers of builders hardware whether or not they are members of BHMA. AMERICAN NATIONAL STANDARD An American National Standard implies a consensus of those substantially concerned with its scope and provisions. An American National Standard is intended as a guide to aid the manufacturer, the consumer and the general public. The existence of an American National Standard does not in any respect preclude anyone, whether he has approved the Standard or not, fi-om manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the Standard. American National Standards are subject to periodic review and users are cautioned to obtain the latest editions. CAUTION NOTICE: This American National Standard may be revised or withdrawn at any time. The procedures of the American National Standards Institute require that action be taken to reaffirm, revise, or withdraw this Standard no later than five years from the date of publication. Purchasers of American National Standards may receive current information on all Standards by calling or writing The American National Standards Institute.

FOREWORD (This Foreword is not a part of ANSI/BHMA Al 56.2) The general classification of builders hardware includes a wide variety of items which are divided into several categories. To recognize this diversity, a sectional classification system has been established. Locks and Lock Trim is one such section and this Standard is the result of the collective efforts of members of the Builders Hardware Manufacturers Association, Inc. who manufacture these products. The total Product Standards effort is therefore a collection of sections, each covering a specific category of items. Performance tests and, where it has been necessary, dimensional requirements have been established to insure safety, security and stability to which the public is entitled. Performance criteria for resistance to surreptitious and forcetil attack are not fully covered. There are no restrictions on design except for those dimensional requirements imposed for the reasons given above. It is also required that locks fit certain cut-out dimensions. This Standard is not intended to obstruct but rather to encourage the development of improved products, methods and materials, The BHMA recognizes that errors will be found, items will become obsolete, and new products and methods will be developed. With this in mind, the Association will update, correct and revise these Standards on a regular basis. It shall also be the responsibility of manufacturers to request such appropriate revisions. Bored locks have been described in three grade levels related to performance and security. Choice of grade and specific products are made on the basis of utility, aesthetics, security objectives and end use desired. The BHMA numbers which indicate functions of locks and latches do not identify grade, finish or design and are not intended to be used without necessary supplementary information. Individual manufacturer’s catalogs are to be consulted. Users of this Standard consult applicable local building codes as to requirements affecting the functions of locks used on fire doors and doors within a means of egress. Some communities require the use of exterior door locks having a dead bolt with a 1 in (25.4 mm) projection for the purpose of providing greater security. Only functions compatible with the requirements of the applicable building codes are used.

SCOPE 1.1 This Standard establishes requirements for bored and preassembled locks and latches and includes performance tests, strength tests, operational tests, material evaluation tests, finish tests, and dimensional criteria. 1.2 Tests described in this Standard are performed under laboratory conditions. In actual usage, results vary because of installation, maintenance and environmental conditions. 1.3 When locks and latches are used in fire door assemblies, they shall have been tested and listed for use in fire doors by a nationally recognized independent testing laboratory and shall be under an in-plant follow-up inspection service. 1.4 See ANSVBHMA A156.13 or Al 56.12 respectively for series 1000 mortise locks and latches or series 5000 interconnected locks and latches. 2. DEFINITIONS 2.1 Backset. The distance from the edge of the door to the centerline of the cylinder at the centerline of the door thickness. 2.2 Bolts 2.2.1 Dead Bolt. A lock component having an end which protrudes from, or is withdrawn into, the lock front by action of the lock mechanism. When the door is closed and the dead bolt thrown, it extends into a hole provided in the strike, locks the door, and will not retract with end pressure. 2.2.2 Latch Bolt. A lock component having a beveled end which projects from the lock front in an extended position but is forced back into the lock case by end pressure or drawn back by action of the lock mechanism. When the door is closed, the latch bolt projects into a hole provided in the strike, and holds the door in a closed position. 2.2.3 Deadlocking Latch Bolt. A spring actuated latch bolt with a beveled end and incorporating a plunger which, when depressed, automatically locks the projected latch bolt against return by end pressure. Also called dead latch. 2.3 Cylinder. The subassembly of a lock containing a plug with keyway and a body with tumbler mechanism. 2.3.1 Cylinder Body. The portion of a cylinder that surrounds the plug and contains the tumbler mechanism. 2.3.2 Cylinder Plug. A component of the cylinder within the body which is actuated when the correct key is inserted. 2.3.3 Interchangeable Core. A cylinder that is removable from the lock with a designated key without disassembly of the lock. 2.4 Cylinder Housing. The portion of a lock that surrounds and retains the cylinder body. It is a lever or knob, part of a lock case or other anchoring means. 2.5 Locks 2.5.1 Preassembled Lock Series 2000. A key in the lever or knob type lock fitting into a notched cutout in a door. 2.5.2 Bored Lock Series 4000. A key in the lever or knob type lock installed in round bored openings in the edge and face of a door. 2.6 Lock Front. A plate fastened to the edge of a door through which the bolts pass. 2.7 Strike. A plate fastened to the door frame into which the bolts project. 2.8 Strike Box. A housing used in back of a strike to enclose the bolt or bolt openings. 5 Licensed to Spark Lock/Raymond Palmer ANSI Store order #X100310 Downloaded: 7/18/2003 11:50:21 AM ET Single user license only.
