1、 ANSI/BHMA A156.1-2016 Revision of ANSI/BHMA A156.1-2013 AMERICAN NATIONAL STANDARD for BUTTS AND HINGES SPONSOR BUILDERS HARDWARE MANUFACTURERS ASSOCIATION, INC. American National Standards Institute Approved December 15, 2016 2 AMERICAN NATIONAL STANDARD An American National Standard implies a con

2、sensus 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 th

3、e 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 i

4、s permitted to be revised or withdrawn at any time.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 current

6、thout specific authorization from BHMA Printed in the USA This Standard was first published June 1969 by the Builders Hardware Manufacturers Association. It was entitled, “Standard 101 BHMA Product Standards Section A Butts and Hinges.“ ANSI approval was secured under the Canvass Method. BHMA was ac

7、credited on 21 March 1983 by ANSI as a sponsor using the Canvass Method. 3 FOREWORD (This Foreword is not a part of ANSI/BHMA A156.1) The general classification of builders hardware includes a wide variety of items which are divided into several categories. To recognize this diversity, a sectional c

8、lassification system has been established. Butts and Hinges is one such section and this Standard is a result of the collective efforts of members of the Builders Hardware Manufacturers Association, Inc. who manufacture this product. The total Product Standards effort is, therefore, a collection of

9、sections, each covering a specific category of items. Performance tests and, where necessary, material and 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 impo

10、sed for reasons given above. It is also required that hinges fit certain cut-out dimensions. 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 th

11、ese Standards on a regular basis. In most cases, products have been described in grade levels related to performance with Grade 1 being the top rating. Grade classifications indicate levels only within their own product category. Choice of grade and specific product are made on the basis of utility,

12、 aesthetics, security objectives and end use desired. The BHMA numbers which indicate types of hardware do not identify size, finish, or design and are not intended to be used without necessary supplementary information. Individual manufactures catalogs are consulted. Users of this Standard consult

13、applicable local building codes as to requirements affecting the functions of hinges used on fire doors. 4 TABLE OF CONTENTS 1. SCOPE . 6 2. DEFINITIONS . 7 3. GENERAL . 8 4. TEST EQUIPMENT 10 5.

15、ical wear tests, friction tests, strength tests, finish tests, and material and dimensional requirements are included. 1.2 Tests described in this Standard are performed under laboratory conditions. In actual usage, results vary because of installation, maintenance and environmental conditions. 1.3
