2、/BHMA A115-2016 Page 2 AMERICAN NATIONAL STANDARD An American National Standard implies 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 A
3、merican National Standard does not in any respect preclude anyone, whether he has approved 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 a
4、re cautioned to obtain the latest editions. CAUTION NOTICE: This American National Standard is permitted to be revised or withdrawn at any time.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
5、years from the date of publication. Purchasers of American National Standards receive current information on all Standards by calling or writing the American National Standards Institute.

7、stitute in a series of individual A115 standards, which are now combined into single documents for steel and wood doors. ANSI approval was secured under the Canvass Method. BHMA was accredited on 21 March 1983 by ANSI as a sponsor using the Canvass Method. This Standard was developed as a joint effo
8、rt by members of SDI, WDMA, DHI, HMMA, BHMA and CSDMA. The committee is grateful to Allan Ashachik for his guidance and technical contributions as the first chairman of the reconstituted group. The BHMA recognizes that errors will be found, items will become obsolete, and new products, methods and m
9、aterials will be developed. With this in mind, the Association plans to update, correct and revise these Standards on a regular basis. It is recommended that individual manufactures catalogs be consulted. Users of this Standard should also consult applicable local building codes as to requirements a

17、ed) ANSI/BHMA A115-2016 Page 5 1. SCOPE AND PURPOSE 1.1 These Standards cover all significant dimensional attributes for mounting common hardware products in steel doors and frames. All dimensions shall be as shown on the accompanying drawings. 1.2 These standards were developed to show only the mos
18、t commonly used preparations for door hardware, and provide targets for standardization. Where multiple configurations are in common usage, separate drawings are provided. For other configurations, it is recognized that these standards may be used in part, or with exceptions, while still providing s
19、ome degree of basic guidance and standardization. 2. GENERAL REQUIREMENTS 2.1 Preparations covered by this standard are intended for use in doors 1 inches (44.5mm) 1/16 inch (1.6mm) in thickness unless otherwise specified. 2.2 The center line of the lock in the door shall be located in reference to
20、the center line of its strike 2.3 Location of Operable Parts in accessible openings shall be between 34 and 48 inches. 2.4 Door Edge Doors shall be furnished with a beveled or square edge unless otherwise specified. 2.5 Door Reinforcement Doors shall be reinforced to support the requirements of the
21、hardware application. 2.6 Tolerances for cutouts are shown on individual drawings. 2.7 Metric Equivalents are shown in the Appendix (inclusion in the individual drawings is not possible due to size constraints). 3. APPLICABLE DOCUMENTS 3.1 ANSI/BHMA Standards A156.2 for Bored and Preassembled Locks
22、and Latches, A156.5 for Auxiliary Locks, A156.12 for Interconnected Locks and Latches, A156.13 for Mortise Locks and Latches, A156.16 for Auxiliary Hardware, and other standards available at . 3.2 Please consult the relevant standards of the participating Associations: Canadian Steel Door Manufactur

DEFINITIONS 4.1 Auxiliary Dead Latch A plunger which, when actuated, automatically locks a
24、projected latch bolt against return by end pressure. 4.2 Auxiliary Locks A lock having a latch bolt or dead bolt operated by a key or a turn or both. This lock is often used in addition to another lock which is or is not key operated but has a latch bolt operated by knobs, levers or thumbpiece. 4.2.
25、1 Bored Dead Latch A lock fitting round bored openings in the face and edge of a door and having a dead latch operated by a key or turn or both. 4.2.2 Bored Dead Lock A lock fitting round bored openings in the face and edge of a door and having a dead bolt operated by a key or turn or both. 4.3 Bore
26、d Locks Bored lock is used herein to designate locks having cylindrical shaped bodies which are ANSI/BHMA A115-2016 Page 6 mounted in holes bored in the door. 4.4 Dead Bolt. A lock component which protrudes from, or is withdrawn into the lock front by action of the lock mechanism. When the door is c
27、losed and the dead bolt is thrown, it extends into a hole provided in the strike, locking the door and does not return with end pressure. 4.5 Door Edge The two vertical surfaces of the door that are perpendicular to the door face. 4.5.1 Beveled Edged Door The angle of the lock or hinge edge of the d
28、oor in relation to the face of the door. The standard bevel is 1/8 inch in 2 inches, or approximately 3 degrees. 4.6 Door Face Surface of the door exposed to view when the door is closed. 4.7 Face Cut Out A piercing of the door face for hardware, lites, louvers or accessories. 4.8 Flush Bolt A type
29、of bolt that when applied it is flush with the edge or face of the door. 4.9 Frame Frame is that portion of an opening which gives a finished appearance to a cutout in a wall and provides a square and plumb opening on which to hang a door. 4.10 Head Horizontal frame member atop of opening or top of
30、transom frame. 4.11 Hinge Face That face of the door viewed when observing the hinge knuckles on the door and frame. 4.12 Interconnected Lock A mechanically interconnected locking mechanism having a separate latch bolt or dead locking latch bolt and dead bolt designed for installation in round bored
31、 openings in the edge and face of a door. 4.13 Latch Bolt A lock component having a beveled end which projects from the lock front in its extended position, but is forced back into the lock case by end pressure or drawn back by action of the lock mechanism. When the door is closed, the latch bolt pr
32、ojects into a hole provided in the strike, holding the door in a closed position. 4.14 Latch Strike A plate fastened to the door or frame into which the bolts project. 4.15 Latch Tube A tubular housing containing the latch bolt and attached to the lock front. 4.16 Lock Backset The horizontal distanc
33、e from the door edge centerline measured at the door thickness, to the centerline of the lock hub or cylinder. 4.17 Lock Case The main body of a mortise lock containing the working mechanism which operates the latch bolt and deadbolt. 4.18 Lock Front A plate fastened to the edge of a door through wh
34、ich the bolt(s) pass. 4.19 Lock Strike A mortised or surface mounted plate fastened to the door frame into which the bolts project. 4.20 Lock Support Component inside the door used to keep the hardware in alignment. 4.21 Mortise Lock A lock or latch fitting into a mortised cavity prepared in the edg
35、e of a door. The bolts are operated by knobs, levers, turns, thumb pieces, paddles or cylinders engaging the mortise lock or latch through holes prepared in the faces of the door. 4.22 Open Back Strike A lock strike for use on pairs of doors permitting the inactive leaf to be opened or closed indepe
36、ndently, eliminating the need for an astragal or coordinator. 4.23 Preassembled Lock A lock fitting into a notched cutout in a door. 4.24 Plaster Guard The shield attached behind the strike reinforcement to prevent mortar or plaster from entering the mounting holes, thus allowing for full projection
37、 of the bolts. 4.25 Reinforced Additional door material which provides structural support for hardware. ANSI/BHMA A115-2016 Page 7 4.26 Round Flush Pull A round pull mortised flush or nearly flush into a door and having a recess to receive fingers to actuate the slide of the door. 4.27 Square Edged
38、Doors The lock and hinge edge of the door is 90 degrees to the face of the door. Also called Universal Edged Doors. 4.28 Stop Face That side of a door viewed when observing the stop side of a frame.
