1、 1 ANSI/BHMA A156.40-2015 AMERICAN NATIONAL STANDARD FOR RESIDENTIAL DEADBOLTS SPONSOR BUILDERS HARDWARE MANUFACTURERS ASSOCIATION, INC. AMERICAN NATIONAL STANDARDS INSTITUTE Approved January 15, 2015 2 AMERICAN NATIONAL STANDARD An American National Standard implies a consensus of those substantial

2、ly 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 man

3、ufacturing, 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 CAUTION NOTICE: This American National Standard may be revised or withdrawn

4、 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

5、by calling or writing the American National Standards Institute.

Printed in the USA The Builders Hardware Manufacturer

6、s Association, Inc first published the basic material in this standard February 1971. 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

7、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 A156.36 for auxiliary locks. 3 FOREWORD (This Foreword is not a part of ANSI/BHMA A156.40) The general classification

8、 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. Residential deadbolts and dead latches is one such Standard is the result of the collective efforts of members of the

9、 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

10、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 e

11、ncourage, 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

12、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 objec

13、tives 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 buildin

14、g 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 wit

15、h the requirements of the applicable building codes are used. 4 CONTENTS 1. SCOPE 5 2. DEFINITIONS 5 3. GENERAL . 7 4.

SCOPE 1.1 ANSI/BHMA A156.40 establishes requirements for residential deadbolts and deadlatches, and includes durabilit

17、y, security, finish tests. Residential deadbolt and deadlatches are generally used for single family homes and multifamily dwellings. 1.2 Tests described in this Standard are performed under laboratory conditions. In actual usage, results vary because of installation, door and frame construction, ma

18、intenance 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 Testing Laboratory (NRTL) and shall be under an in-plant follow-up inspection service. 1.4 Residential Grade Qu

19、alifications Manufacturers shall indicate the Grade level of their locks for each of the three categories listed (Durability, Strength and Security, and Finish). Locks shall meet all tests for their grade listing for each of the categories independently. A Grade A lock for a specific category shall

20、meet all Grade A criteria for that category, and a Grade B lock for a specific category shall meet all Grade B criteria for that category, and a Grade C lock for a specific category shall meet all Grade C criteria for that category. 2. DEFINITIONS 2.1 Residential Deadlock A lock having a latchbolt o

21、r deadbolt operated by a key and/or turn, and usually used in addition to a primary 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 2.3.1 Auxiliary Dead Latch A plung

22、er which, when actuated, automatically locks a projected latch bolt against return by end pressure. 2.3.2 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

23、 into a hole provided in the strike, locks the door, and does not retract with end pressure. 2.3.3 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 me

24、chanism. When the door is closed, the latch bolt projects into a hole provided in the strike, and holds the door in a closed position. 2.3.4 Deadlocking Latch Bolt A spring actuated latch bolt with a beveled end and incorporating a plunger which, when depressed, automatically locks the projected lat

25、ch bolt against return by end pressure. Also called dead latch. 2.3.5 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 opera

26、ted 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. 6 2.7 Cylinder The subassembly of a mechanical lock containing a plug with keyway and a body

27、with movable detainers. 2.8 Cylinder Body The portion of a cylinder that surrounds the plug and contains the movable detainers. 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 f

28、rom wrenching, cutting, pulling or prying. 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. 2.11 Cylinder Plug A component of the cylinder within the body, which is actuated when the correct key is used. 2.12 Key

29、A properly combinated device specifically intended to operate a corresponding cylinder. 2.13 Lock Front A plate fastened to the edge of a door through which the bolts pass. 2.14 Mortise Dead Latch A lock fitting a mortised cavity prepared in the edge of a door and having a latch bolt and an auxiliar

30、y 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. 2.15 Mortise Dead Lock A lock having a dead bolt and otherwise the same as a mortise dead latch. 2.16 Movable Detainer Part of the mechanism of the cylinder which first sh

31、ould 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. 2.17 Mounting Plate A plate mounted on the inside of a door through which mounting bolts pass to attach the outside locking mechanism.

32、 2.18 Rim Lock A lock mounted on the inside face of a door. 2.19 Strike A mortised or surface mounted plate fastened to the door frame into which the bolts project. 2.19.1 Armored Strike A strike reinforced in such a way as to strengthen the frame to which it is applied. 2.20 Strike Box A housing us

33、ed in back of a strike to enclose the bolt or bolt openings. 2.21 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. 2.22 Turn The component that projects

34、or retracts a dead bolt or latch bolt by turning. Sometimes called a turnpiece or thumbturn. 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 A156.5-2014 for Cylinders and Input De

35、vices 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,

36、 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

37、 security protections are required users should consider locks meeting UL 437 or ANSI/BHMA A156.30 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

38、 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 pre

39、parations described in the ANSI/BHMA A156.115 Series. Other configurations are permitted to fit special opening templating requirements.
