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, and continues to participate actively in the ANSI process. 3 FORWARD (This Forward is not a part of ANSI/BHMA A156.4-2013) The general classification of builders hardware includes a wide variety of items whic
8、h are divided into several categories. To recognize this diversity, a sectional classification systems has been established. Door Controls is one such section and this Standard is the result of the collective efforts of members of the Builders Hardware Manufacturers Association, Inc., who manufactur
9、e this product. The total Product Standards 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 e
10、ntitled. There are no restrictions on design, 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 produc
11、ts, 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 related to performance. Grade classifications indicate levels only with their own catego
12、ry. Choice of grade and specific product 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 identify size, finish, material or options and are not intended to be used without necessary supplem
13、entary information. Consult individual manufacturers catalog. 4 Table of Contents 1. SCOPE . 5 2. GENERAL . 5 3. PREPARATION FOR PERFORMANCE TEST . 6 4.
