2、dard 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
3、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
4、National Standard may be revised or withdrawn at any time.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 rece
5、ive the current information on all standards by calling or writing the American National Standards Institute.

6、in the USA The Builders Hardware Manufacturers Association, Inc first published this standard February 1971. It was entitled “Standard 501 BHMA Product Standards Section E, Auxiliary Locks.“ ANSI approval was secured under the Canvass Method. BHMA was accredited on 21 March 1983 by ANSI as a sponsor
7、 using the Canvass Method. 3 FOREWORD (This Foreword is not a part of ANSI/BHMA A156.5) This Standard is the result of the collective efforts of members of the Builders Hardware Manufacturers Association, Inc. who manufacturer cylinders and input devices for locks The total Product Standards effort
8、is a collection of standards , 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 dimensio
9、nal 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 w
10、ill 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, prod
11、ucts 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
12、 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 commun
13、ities 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. In 2008, the BHMA subcommittee revising A156.5 amended the stand
14、ard to recognize the increased application of electrical input products with analogous functions to the traditional mechanical cylinders. At the same time, the auxiliary locking products were removed and placed in a new dedicated standard, A156.36. 4 TABLE OF CONTENTS 1. SCOPE 5 2. DEFINITIONS . 5 3

16、 establishes requirements for mechanical cylinders, electrified input devices, and push button mechanisms, which include operational and strength tests. 1.2 Related products are covered in additional BHMA Publications: A156.25 ANSI/BHMA A156.28 for Master Keying Systems, and ANSI/BHMA A156.30 for Hi
17、gh Security Cylinders and Input Devices.1.3 Auxiliary Locks previously included in this Standard are now found in ANSI/BHMA A156.36 for Auxiliary Locks. 1.4 Tests described in this Standard are performed under laboratory conditions. In actual usage, results vary because of installation, maintenance
18、and environmental conditions. 1.5 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 fixtures applicable to that particula
19、r 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 guidance of or consultation with an independ
20、ent physical security specialist. 1.6 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 availab
21、le in multiple performance grades to suit the application. In order to enhance security and reduce risk, you should consult a qualified locksmith or other security professional. For applications where pick resistance and other higher security protections are required consider locks meeting UL 437-20
22、13 Key Locks, or ANSI/BHMA A156.30-2010 for High Security Cylinders. 1.7 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, a Grade 2 product shal
23、l meet all Grade 2 criteria, and a Grade 3 product shall meet all Grade 3 criteria in each classification. 2. DEFINITIONS 2.1 Bitting 1. the number(s) which represent(s) the dimensions of the key, 2. the actual cut(s) or combination of a key 2.3 Cam 1. a lock or cylinder component which transfers th

25、EROM chips and “touch memory” modules. 2.6 Credential A key, keycard, electronic key fob, PIN (personal identification number), biometric attribute, or other device, used in contact or proximity of the input device to transfer a code required for unlocking the locking device, or communicating with i
26、t for other access control purposes. 2.7 Cylinder The subassembly of a mechanical lock containing a plug with keyway and a body with movable detainers. 6 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 cy
27、linder 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. 2.10 Cylinder Housing The portion of a mechanical lock that surrounds and retains the cylinder body. It is often part of a lock
28、 itself. 2.11 Cylinder Plug A component of the cylinder within the body, which is actuated when the correct key is used. 2.12 Electrified Input Devices The electrified locks equivalent to a cylinder for reading a credential and transmitting the “key code” to the controlling device. Examples include

32、.20 Mechanical Pushbutton Mechanism Decodes the input and releases a control shaft to activate the lock drive mechanism. 2.21 Mortise Cylinder A threaded cylinder, regularly supplied with a cam to actuate the lock mechanism. 2.22 Movable Detainer Part of the mechanism of the cylinder which first sho
33、uld 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. 2.23 Optical Readers Single or bi-directional readers employing optical sensors for decoding visible credentials (bar codes and diagram
34、s) or infrared serial transmissions. 2.24 Push Button Mechanism A mechanical coding device used in place of a key and cylinder. 2.25 Radio Frequency Readers Single or bi-directional readers employing antennas for decoding contactless RFID tags and proximity badges. 2.26 Recessed Cylinder A cylinder
