6、 without specific authorization from BHMA Printed in the USA This Standard was first published in July 1980 by the Builders Hardware Manufacturers Association, Inc. It was entitled, “Standard 301 BHMA Product Standards Section C, Door Controls (Closers).“ ANSI approval was secured under the Canvass
7、Method. BHMA was accredited on 21 March 1983 by ANSI as a sponsor using the Canvass Method. 3 FOREWORD (This Foreword is not a part of ANSI/BHMA A156.14) The general classification of builders hardware includes a wide variety of items which are divided into several categories. To recognize this dive
8、rsity, a sectional classification system has been established. Sliding and Folding Door Hardware is one such section and this Standard is the result of the collective efforts of members of the Builders Hardware Manufacturers Association, Inc., who manufacture this product. The total Product Standard
9、s effort is, therefore, a collection of sections, each covering a specific category of items. Performance tests and, where it has been necessary, dimensional requirements have been established to insure safety, security and stability to which the public is entitled. There are no restrictions on desi
10、gn, except for those dimensional requirements imposed for the reasons given above. It is also required that some hardware items fit certain specified cutout dimensions. The BHMA recognizes that errors will be found, items will become obsolete, and new products, methods and materials will be develope
11、d. 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 related to performance. Grade classifications indicate levels only within their own category. Choice of grades and specific produc
12、ts are made on the basis of utility, aesthetics, security objectives and end use desired. The BHMA numbers and pictorials which indicate types of hardware do not necessarily identify size, finish, or material and are not intended to be used without necessary supplementary information. Individual man
13、ufacturers catalogs are consulted. 4 TABLE OF CONTENTS 1. SCOPE 5 2. DEFINITIONS 5 3. TEST PROCEDURES 6 6. FOLDING DOORS 10 7. FINISH TESTS (APPLICABLE TO ALL DOOR TYPES). 12 8.
