AMERICAN NATIONAL STANDARDS INSTITUTE Approved December 9, 2014 2 An American National Standard implies a consensus of those substantially
2、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 manuf
3、acturing, 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 is permitted to be revised or
4、 withdrawn at any time. The procedures of the American National Standards Institute require that action can be taken to reaffirm, revise, or withdraw this standard no later than five years from the date of publication.

6、tion from BHMA Printed in the USA This Standard was first published May 1977 by the Builders Hardware Manufacturers Association Inc. It was entitled “Cabinet Lock Standard BHMA 511-1977“. ANSI approval was secured under the Canvass Method. BHMA was accredited on 21 March 1983 by ANSI as a sponsor us
7、ing the Canvass Method. 3 FOREWORD (Not a part of ANSI/BHMA A156.11) 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. Cabinet Locks is one s
8、uch 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. Performanc
9、e tests and, where it has been necessary, dimensional requirements have been established to insure safety 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. The BHMA recognizes that errors
10、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. The BHMA numbers which indicate types of hardware do not identify size, finish, or design a
11、nd are not intended to be used without necessary supplementary information. Users of this Standard who require a specific design for a product type should describe it using generic terms or the manufacturers name and description desired. 4 TABLE OF CONTENTS 1. SCOPE 5 2.

EXPLANATION OF IDENTIFYING NUMBERS 18 APPENDIX A (NOT A PART OF ANSI/BHMA A156.11) 19 5 1. SCOPE 1.1 This sta
13、ndard establishes requirements for Cabinet Locks used on doors, drawers and furniture. Cycle tests, operational tests, strength tests and finish tests are included. 1.2 Tests described in this Standard are performed under laboratory conditions. In actual usage, results vary because of the material u
14、sed in the installation, maintenance and environmental conditions. 1.3 The intent of this standard is to provide fair, uniform and repeatable testing of locking cylinders and input devices used in commercially available door hardware. Each testing section of the standard identifies the tools and/or
15、fixtures applicable to that particular test. We recognize that any cylinder can be compromised or destroyed by excessive force or extended time or by the use of custom designed tools or techniques. For cylinders and input devices to be used beyond the scope of this standard, we recommend the guidanc
16、e of or consultation with an independent physical security specialist. 1.4 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 commo
17、n 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
18、should consider locks meeting ANSI/UL 437 or ANSI/BHMA A156.30 for High Security Cylinders. 1.5 Grade Qualifications Two classifications of tests are described in this Standard, Operational and Security. Manufacturers shall indicate the Grade level. A Grade 1 product shall meet all Grade 1 criteria,
19、 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 Bolts 2.1.1 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 t
20、he door or drawer is closed and the dead bolt is thrown, it extends into a hole provided in the strike or if no strike is used, behind the frame, thus locking the door or drawer. It does not retract with end pressure. 2.1.2 Extension Bolt A type of dead bolt which projects laterally after entering t
21、he strike and interlocks with the strike. 2.1.3 Hook Bolt A type of dead bolt which after entering the strike expands and interlocks with the strike. 6 2.1.4 Latch Bolt A lock component having a beveled end which projects from the lock front in its extended position, is forced back into the lock cas
22、e by end pressure or drawn back by action of the lock mechanism. When the door or drawer is closed, the latch bolt projects into a hole provided in the strike or if no strike is used, behind the frame, thus holding the door or drawer in the closed position. 2.2 Case The housing of a lock. 2.3 Cycle
23、In this Standard, the projection and retraction of a bolt or the rotation of a cam to the locked and unlocked position. 2.4 Cylinder The subassembly of a lock containing a plug with a keyway and a body with movable detainers. 2.5 Strike A plate fastened to the frame into which or behind which the bo
24、lt projects. 2.6 Interchangeable Core A cylinder that is removed from the lock with a designated key or other means which does not require disassembly of the lock. 3. GENERAL 3.1 If cabinet locks are to be keyed into a master key system, or into a larger overall system, the user of this Standard sha
25、ll so specify. 3.2 Provisions for cylinders contained in ANSI/BHMA A156.5 - 2014 for Auxiliary Locks and Associated Products shall not apply to cylinders in this Standard. 3.3 Values Required values in this Standard are given in US units. The SI (metric) equivalents are approximate. All values which
26、 do 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 opening shall be 2 degrees. 3.4 Reference to other Standards ANSI Standards are available at or from the Am
27、erican National Standards Institute, www.ansi.org. 4. TYPES (SEE SECTION 9) 4.1 Cam Locks Cam locks are installed in drawer fronts and in cabinet doors through a mounting cutout (bore) from the outside or inside and secured from the inside with a nut, a spring clip, screws, or by other means. Cams a
28、re rotated by turning a key. Cams are positioned at any position within 360 degrees and can be rotated 90 degrees, 180 degrees, or other rotations as specified in manufacturers catalogs. Cams shall be straight, offset, hook, or of other similar configurations. 4.2 Chest Locks Chest locks are install
29、ed from the inside of the door frame of the cabinet, inserting the cylinder or barrel into a cutout (bore) in the door or frame. The surface of the cylinder is flush or protrudes slightly above the outer surface. Surface mounted cases attach to the inner surface of the door and half mortise locks ar
30、e partially mortised into the back. Cases are attached to doors or frames with screws or other methods standard with the manufacturer. 7 4.3 Cabinet Door or Drawer Locks Drawer or cabinet door locks are installed from inside of the drawer or door, inserting the cylinder or barrel into a cutout (bore
31、) in the drawer front or door. The surface of the cylinder is flush or slightly above the outer surface. Surface mounted cases attach to the inner surface of the drawer front or door and half mortise lock cases are partially mortised into the back. Cases are attached to drawers and doors with screws
