1、 ANSI/BHMA A156.36-2010 AMERICAN NATIONAL STANDARD FOR AUXILIARY LOCKS SPONSOR BUILDERS HARDWARE MANUFACTURERS ASSOCIATION, INC. Approved by the American National Standards Institute September 29, 2010 2AMERICAN 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 CAUTION NOTICE: This American National Standard may be revised or withdrawn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. 3FOREWORD (This Foreword is not a part of ANSI/BHMA A156.36) 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. Auxiliary Locks and Latches is one such section and this Standard is the result of the collective efforts of members
9、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 e
10、nsure 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 rathe
11、r 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
12、 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
13、 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 b
14、uilding 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 compatib
15、le 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 c
16、reate two standards, and dedicate A156.5 to Cylinders, resulting in the first edition of this Standard. 4CONTENTS 1. SCOPE 5 2. DEFINITIONS 5 3. GENERAL 7 4.

37、hall meet the performance requirements for the appropriate types and grade level found in the ANSI/BHMA Standard A156.5-2010 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 secu
38、rity 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
39、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 A156.30 for High Security Cylinders. 3.3 Tolerances Where
40、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 fo
41、rce 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 A156.115 Series. Other configurations are permitted to fit special opening templating requirements. See manufact
42、urers 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 , www.ansi.org, www.astm.org, and . 3.7 Values Required values in this Stand
43、ard 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.
