1、ANSI/BHMA A156.36 - 2016 Revision of ANSI/BHMA A156.36-2010 AMERICAN NATIONAL STANDARD FOR AUXILIARY LOCKS SPONSOR BUILDERS HARDWARE MANUFACTURERS ASSOCIATION, INC. AMERICAN NATIONAL STANDARDS INSTITUTE Approved November 7, 2016 2 AMERICAN NATIONAL STANDARD An American National Standard implies a co
2、nsensus 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 t
3、he 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
4、 may be revised or withdrawn at any time.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 i
5、nformation on all standards by calling or writing the American National Standards Institute.

Printed in the USA The Bu
6、ilders Hardware Manufacturers 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
7、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 A156.36 for auxiliary locks. 3 FOREWORD (This Foreword is not a part of ANSI/BHMA A156.36
8、) 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 co
9、llective 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
10、, 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 int
11、ended 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
12、, 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 u
13、tility, 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 Standar
14、d 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 secur
15、ity. 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,
16、 it would be preferable to create two standards, and dedicate A156.5 to Cylinders, resulting in the first edition of this Standard. 4 CONTENTS 1. SCOPE 5 2. DEFINITIONS 5 3. GENERAL 7 4.

18、ANSI/BHMA A156.36 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 describ
19、ed 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 req
20、uirements 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.

Sometimes called a turnpiece or thumbturn. 7 3. GENERAL 3.1 Cylinders and Input Devices for Locks shall
37、meet the performance requirements for the appropriate types and grade level found in the ANSI/BHMA Standard A156.5-2014X 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
38、 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 enha
39、nce 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 only
40、 minus tolerances are given, the dimensions are permitted to be exceeded at the option of the manufacturers.
