1、 1 ANSI/BHMA A156.12 2013 Revision of ANSI/BHMA A156.12-2005 AMERICAN NATIONAL STANDARD FOR INTERCONNECTED LOCKS SPONSOR BUILDERS HARDWARE MANUFACTURERS ASSOCIATION, INC. AMERICAN NATIONAL STANDARDS INSTITUTE Approved March 7, 2013 2 3 AMERICAN NATIONAL STANDARD An American National Standard implies

2、 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 he has appro

3、ved 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 National Sta

4、ndard is permitted to be revised or withdrawn at any time.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 receive

5、current information on all standards by calling or writing the American National Standards Institute.

BHMA was accredited on 21 March 1983 by ANSI as a sponsor using the Canvass Method. 4 FOREWORD (This Foreword is not a part of ANSI/BHMA A156.12) The general classification

7、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. Interconnected Locks is one such section and this Standard is a result of the collective efforts of members of the Bui

8、lders 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, material and dimensional requirements have been established to

9、insure safety and stability to which the public is entitled. There are no restrictions on design except for those dimensional requirements imposed for reasons given above. This Standard is not intended to obstruct but rather to encourage the development of improved products, methods and materials. T

10、he 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 regular basis. In most cases, products have been described in grade levels

11、related to performance. Choice of grade and specific product are to be made on the basis of utility, aesthetics, security objectives and end use desired. The BHMA numbers which indicate functions of interconnected locks do not identify grade, finish, or design and are not intended to be used without

12、 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 mean of egress. Some communities require use of exterior doo

13、r 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. 5 TABLE OF CONTENTS 1. SCOPE 6 2. DEFINITIONS 6 3. GENERAL 9 4. DIMENSIONAL CHARACTERISTICS 9 5. DESC

15、RT OF ANSI/BHMA A156.12) 36 6 1. SCOPE 1.1 This Standard establishes performance requirements for Interconnected Locks and and includes operational, cycle, strength, material evaluation, security, and finish tests. 1.2 Tests described in this Standard are performed under laboratory conditions. In ac

16、tual usage, results vary because of installation, door and frame construction, maintenance and environmental conditions. 1.3 Grade Qualifications (Also See Appendix A.) Manufacturers shall indicate the Grade level of their locks. Locks shall meet all tests for their grade listing. A Grade 1 lock sha

17、ll meet all Grade 1 criteria, a Grade 2 lock shall meet all Grade 2 criteria, and a Grade 3 lock shall meet all Grade 3 criteria in each classification. 2. DEFINITIONS 2.1 Armored Strike A strike reinforced in such a way as to strengthen the frame to which it is applied. 2.2 Auxiliary Lock A lock ha

18、ving a latch bolt or dead bolt operated by a key, paddle and/or turn, and usually used in addition to a primary lock or latching device. 2.3 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. 2.4 Bitt

Other mechanisms are permitted to be used in lieu of cylinders providing the performance and security criteria are equivalent to that of cylinders. Suffix D shall be indicated in the certified products director

47、y for locks to be used only with drill resistance cylinders as evaluated in A156.5. 3.2 Tolerances Where only minus tolerances are given, the dimensions are permitted to be exceeded at the option of the manufacturers.
