1 ANSI/BHMA A AMERICAN NATIONAL STANDARD FOR AUXILIARY LOCKS SPONSOR BUILDERS HARDWARE MANUFACTURERS ASSOCIATION, INC. Approved by the American National Standards Institute September 29, 2010

2 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, from 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 CAUTION NOTICE: This American National Standard may be revised or withdrawn at any time.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 the current information on all standards by calling or writing the American National Standards Institute. Published by BUILDERS HARDWARE MANUFACTURERS ASSOCIATION, INC. 355 Lexington Avenue New York, New York Copyright 2010 by the Builders Hardware Manufacturers Association, Inc. Printed in the USA The Builders Hardware Manufacturers Association, Inc. first published the basic material in this standard February It was entitled Standard 501 BHMA Product Standards Section E, Auxiliary Locks. ANSI approval was secured under the Canvass Method, leading to the publication of ANSI/BHMA A156.5, which included both cylinders and auxiliary locks. BHMA was accredited on 21 March 1983 by ANSI as a sponsor using the Canvass Method. In 2010, BHMA published updates of A156.5 being dedicated to cylinders, and a new A for auxiliary locks. 2

3 FOREWORD (This Foreword is not a part of ANSI/BHMA A156.36) 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. Auxiliary Locks and Latches 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 this product. The total Product Standards effort is, therefore, a collection of sections, each covering a specific category of items. Performance tests, and, where necessary, dimensional requirements, have been established to ensure safety, security and stability to which the public is entitled. 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 cutout 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, methods, and materials will be developed. With this in mind, the Association plans to update, correct, and revise these Standards on a regular basis. It shall also be the responsibility of manufacturers to request such appropriate revisions. In most cases, products have been described in grade levels related to performance and security. Choice of grade and specific product is made on the basis of utility, aesthetics, security objectives and end use desired. The BHMA numbers, which indicate types of hardware do not identify grade, finish, or design and are not intended to be used without necessary supplementary information. Individual manufacturers' catalogs are 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. Most of the products in this Standard were covered in ANSI/BHMA A156.5 for Auxiliary Locks through the 2001 edition. Section E determined in 2005, due to the increasing variety and complexity of products, it would be preferable to create two standards, and dedicate A156.5 to Cylinders, resulting in the first edition of this Standard. 3

5 1. SCOPE 1.1 ANSI/BHMA A establishes requirements for Auxiliary Locks, and includes dimensional criteria and five classifications of tests: operational, cycle, strength, security and, finish. This Standard was formerly part of ANSI/BHMA A156.5 for Auxiliary Locks and Associated Products. 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 Grade Qualifications Manufacturers shall indicate the Grade level to which their product is certified. Products shall meet all Grade requirements for tests listed in 1.1., A Grade 1 product shall meet all Grade 1 criteria, a Grade 2 product shall meet all Grade 2 criteria, and a Grade 3 product shall meet all Grade 3 criteria in each classification. 2. DEFINITIONS 2.1 Auxiliary Lock A lock having a latch bolt or dead bolt operated by a key, paddle and/or turn, and usually used in addition to a primary lock or latching device. 2.2 Backset The distance from the edge of the door measured at the centerline of the door thickness to the centerline of the function holes or cross bore. 2.3 Bolts Auxiliary Dead Latch A plunger which, when actuated, automatically locks a projected latch bolt against return by end pressure 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 does not retract with end pressure 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 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 Expanding or Interlocking Type Dead Bolt A bolt which interlocks with its strike when fully engaged. 2.4 Bored Dead Latch A lock fitting round bored openings in the face and edge of a door and having a deadlocking latch bolt operated by a key or turn or both. 2.5 Bored Dead Lock A lock fitting round bored openings in the face and edge of a door and having a dead bolt operated by a key or turn or both. 2.6 Case The housing of a lock. 2.7 Cylinder The subassembly of a mechanical lock containing a plug with keyway and a body with movable detainers. 2.8 Cylinder Body The portion of a cylinder that surrounds the plug and contains the tumbler mechanism. The cylinder body is sometimes called a cylinder shell. 2.9 Cylinder Guard That portion that surrounds the otherwise exposed portion of a cylinder to protect the cylinder from wrenching, cutting, pulling or prying. 5

6 2.10 Cylinder Housing The portion of a mechanical lock that surrounds and retains the cylinder body. It is often part of a lock itself Cylinder Plug A component of the cylinder within the body, which is actuated when the correct key is used Key A properly combined device specifically intended to operate a corresponding cylinder Lock Front A plate fastened to the edge of a door through which the bolts pass Mortise Dead Latch A lock fitting a mortised cavity prepared in the edge of a door and having a latch bolt and an auxiliary dead latch operated by a key or turn or both. The key or turn engage the lock through holes prepared in the faces of the door Mortise Dead Lock A lock having a dead bolt and otherwise the same as a mortise dead latch Movable Detainer Part of the mechanism of the cylinder which first should be moved by the key into a predetermined position before the key or plug can release. Examples include components known as pins, side bars, discs, and the like Mounting Plate A plate mounted on the inside of a door through which mounting bolts pass to attach the outside locking mechanism Narrow Stile Latch A device for automatically retaining the door in the closed position. Typically operated by lever or paddle inside, and key, lever or paddle outside Narrow Stile Dead Latch A lock having a latch bolt and an auxiliary dead latch and operated by a key, push button mechanism, lever, paddle, or a turn. The lock is typically used in aluminum doors with stiles as narrow as 2 in.(51 mm) but is also used on other doors Narrow Stile Dead Lock A lock having a dead bolt and operated by a key, push button mechanism, lever, paddle or a turn. The lock is typically used in aluminum doors with stiles as narrow as 2 in. (51 mm) but is also used on other doors Paddle The component that projects or retracts a dead bolt or latch bolt by pushing or pulling Rim Lock A lock mounted on the inside face of a door Strike A mortised or surface mounted plate fastened to the door frame into which the bolts project Armored Strike A strike reinforced in such a way as to strengthen the frame to which it is applied Strike Box A housing used in back of a strike to enclose the bolt or bolt openings Tailpiece A bar projecting from the back of a rim, bored lock cylinder or a push button mechanism engaging the lock mechanism and when rotated by the key or turn either locks or unlocks the lock Turn The component that projects or retracts a dead bolt or latch bolt by turning. Sometimes called a turnpiece or thumbturn. 6

7 3. GENERAL 3.1 Cylinders and Input Devices for Locks shall meet the performance requirements for the appropriate types and grade level found in the ANSI/BHMA Standard A for Cylinders and Input Devices for the lock to retain its grade listing. Assemblies take the grade level of the lowest graded component. 3.2 No lock can provide complete security by itself. Locks may be defeated by forcible or technical means, or evaded by entry elsewhere on the property. No lock can substitute for caution, awareness of your environment, and common sense. Builders hardware is available in multiple performance grades to suit the application. In order to enhance security and reduce risk, consult a qualified locksmith or other security professional. For applications where pick resistance and other higher security protections are required users should consider locks meeting UL 437 or ANSI/BHMA A for High Security Cylinders. 3.3 Tolerances Where only minus tolerances are given, the dimensions are permitted to be exceeded at the option of the manufacturers. All values which do not carry specific tolerances or are not marked maximum or minimum shall have the following tolerances: Linear dimensions shall be ± 1/16 in (1.6 mm). Pounds or pound force shall be ± 2%. Degrees shall be ± 2 degrees. 3.4 Door and Frame Preparation The lock models described in this standard shall fit the door and frame preparations described in the ANSI/BHMA A Series. Other configurations are permitted to fit special opening templating requirements. See manufacturers instructions for details. 3.5 Trim Roses, escutcheons, knobs, levers, turns, paddles, cylinder guards shall cover all door preparation openings. 3.6 Reference to other Standards Referenced standards are available from and Values Required values in this Standard are given in US units. The SI (metric) equivalents are approximate. 3.8 Codes Certain lock functions described in this Standard are not permitted on doors within a means of egress. Consult local Authority Having Jurisdiction. When locks and latches are used in fire door assemblies, they shall be listed for use in fire doors by a Nationally Recognized Testing Laboratory (NRTL) and shall be under an in-plant follow-up inspection service. 3.9 When any function of lock combines a dead bolt and auxiliary dead latch, the auxiliary dead latch shall be effective whether or not the dead bolt is projected. 4.

30 APPENDIX A USER'S GUIDE (NOT A PART OF ANSI/BHMA A156.36) A-1 FUNCTIONS AND GRADE LEVELS OF LOCKS A-1.1 Dead bolt locks are usually the most secure. Those wishing a relatively high level of security specify Grade 1 or 2. Grade 3 is generally adequate in areas where the threat is an attack of opportunity and where the attack is expected to be of short duration. A-2 TRIM A-2.1 Because of the security tests imposed, there are no material requirements in this Standard. If trim of minimum thickness or a specific material is wanted, so specify. Materials most commonly used are aluminum, brass, bronze, 300 Series stainless steel and zinc alloy. A-2.2 If specific trim designs are desired, so specify. A-4 DOORS AND FRAMES The provisions of this Standard evaluate locks as a component and do not take under consideration the variety of doors, frames and other components available, some of which are vulnerable under the kinds of attacks described. Select doors, frames and surrounding wall systems compatible with the level of lock security selected. A-5 FASTENERS Where lock strikes are applied to wood frames under 1 inch (25.4 mm) thick, screws normally furnished are sometimes inadequate. Specify screws of sufficient length to engage the structural stud behind the frame. A-6 FINISHES See ANSI/BHMA Standard A for Materials and Finishes for a description of the finishes. Other available finishes are found in individual manufacturer's catalogs. MOUNTING BLOCKS FOR TESTING For consistent test results, the following mounting block material specifications are recommended: Euro Birch, Yellow Birch or Baltic Birch is the preferred type of plywood because of the tight control on voids and other imperfections. Three pieces are bonded together with alternating ply, PVA glue and a cold press method. The resulting block has 33-ply, consisting of two ½ outer sections with 10-ply and one ¾ center section with 13-ply. FAS Grade Clear Maple. 30
