6、uced without specific authorization from BHMA Printed in the USA This Standard was developed by the Builders Hardware Manufacturers Association, Inc. It was approved by ANSI under the Canvass Method. BHMA was accredited on 21 March 1983 as a sponsor using the Canvass Method. 3 FOREWORD (This Forewor
7、d is not a part of ANSI/BHMA A156.38) 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. Power Operated Doors is one such section and this Sta
8、ndard 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 sections, each covering a specific category of items. Performance tests and, where necessary
9、, dimensional requirements have been established to ensure a degree of safety. There are no restrictions on design except for those dimensional requirements imposed for reasons of safety. This Standard is not intended to obstruct but rather to encourage the development of improved products, methods
10、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 and revise these Standards on a regular basis. It shall also be the responsibility of manuf
11、acturers to request such appropriate revisions. 4 TABLE OF CONTENTS 1. GENERAL .5 2. DEFINITIONS .6 3. REQUIREMENTS FOR LOW ENERGY POWER OPERATED SLIDING DOORS 7Error! Bookmark not defined. 4.

F ig u re 1Figure 1 9 APPENDIX (NOT A PART OF ANSI/BHMA A156.38) A-1 CONFORMANCE CRITERIA Certification that products offered meet the requirements of this Standard and conform to individual manufacturers drawings, specifications, standard
40、s and quality assurance practices are available and in some circumstances are required. Buyer requirements determine the need for proof of conformance such as first article inspection, test laboratory reports or listings. Specifiers requiring assertions of conformance utilize statements of conforman
41、ce by individual manufacturers, or test reports acceptable to the buyer. A-2 PRESERVATION, PACKAGING, AND PACKING Unless other arrangements between buyer and seller are made, preservation, packaging and packing shall be sufficient to protect containers and their contents under normal shipping and ha
42、ndling conditions from the source of supply to the destination point. A-3 MARKING Unless other arrangements between buyer and seller are made, marking shall be in accordance with the individual manufacturers standard practice. A-4 APPLICATION As described by the title, Low Energy, this Standard appl
43、ies to products designed to open and close slowly with minimal kinetic energy. Their primary application is to provide increased accessibility through doorways. A-5 KNOWING ACT SWITCHES The switch should be located a maximum distance of 12 feet from the center of the door, remain accessible when the
44、 door is opened, and shall not be located in a position where the user would be in the path of the moving door. It is generally preferable for the switch to be located within one to five feet from the door. If located more than 12 feet from the center of the door, an additional time delay beyond the
45、 five second minimum is recommended. The additional time delay should be a minimum of one second for each additional foot of distance. The switch should be installed a minimum of 34 in. (864mm) and a maximum of 48 in. (1219mm) from the floor, or as specified by the local building code. The switch sh
46、ould be mounted so the user can see the door when activating. Acceptable switching methods include: wall or jamb-mounted contact switches such as push plates; fixed non-contact switches that have a detection range no greater than 12 inches (305mm) ( to ensure a knowing act is utilized to activate th
47、e door); the action of manual opening (pulling) a door; and controlled access devices such as keypads, card readers, and keyswitches. Consult A117.1 and other applicable building codes for additional information regarding accessibility requirements for the door and area around the door. A-6 RECOMMEN
48、DED MAINTENANCE AND INSPECTION The manufacturer should provide an owners manual with the sale of each operator to explain how the owner should perform regular safety checks. Low Energy doors require periodic maintenance and inspection to ensure compliance with this standard. It is strongly recommend
49、ed that they are inspected at the time of installation, and at a minimum annually thereafter, 10 by an AAADM certified inspector. It is also recommended that the doors are maintained on a regular basis by a qualified professional per the manufacturers instructions. Compliance to current standards at the time of service is encouraged. A-7 RECOMMENDED PRACTICES AND OTHER INFORMATION The following comments are provided for guidance in Custom Installations recognizing there will be certain installations that require deviation
