1、 1 ANSI/BHMA A156.9-2015 Revision of ANSI/BHMA A156.9 - 2010 AMERICAN NATIONAL STANDARD FOR CABINET HARDWARE AMERICAN NATIONAL STANDARDS INSTITUTE Approved October 14, 2015 Sponsor BUILDERS HARDWARE MANUFACTURERS ASSOCIATION, INC. 2 AMERICAN NATIONAL STANDARD An American National Standard implies a
2、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 American National Standard does not in any respect preclude anyone, whether he has approve
3、d 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 are cautioned to obtain the latest editions. CAUTION NOTICE: This American National Standa
4、rd is permitted to be revised or withdrawn at any time.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 years from the date of publication. Publishers of American National Standards receive cur
5、rent information on all Standards by calling or writing the American National Standards Institute.

6、ed without specific authorization from BHMA Printed in the USA This Standard was first published November 1968 by the Builders Hardware Manufacturers Association. It was entitled “Standard 201 BHMA Product Standards Section B, Cabinet Hardware.“ BHMA was accredited on 21 March 1983 by ANSI as a spon
7、sor using the canvass method. 3 FOREWORD (This Foreword is not a part of A156.9) 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. Cabinet ha
8、rdware 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 Standards effort is, therefore, a collection of sections, each covering a specific category of item
9、s. Performance tests, and where it has been necessary, material requirements, have been established to insure safety and stability to which the public is entitled. There are no restrictions on design. Cabinet hardware described in this Section represents a cross-section of that which is available to
10、day. However, since cabinet hardware styling and functional application is constantly changing, new items are not to be excluded. Each manufacturer of this type of hardware shall determine which of its products will meet these requirements. On all items, styling is optional. The BHMA recognizes that
11、 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. Cabinet hardware products generally have been described in three levels of performa
12、nce. Choice of product is made on the basis of utility, aesthetics, security objectives and end use desired. As a general guide, Grade 1 is the highest and is suitable for most institutional applications, Grade 3 is suitable for most residential uses, and Grade 2 is often used in all applications. T
13、he 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. 4 TABLE OF CONTENTS 1.

(610 mm) centers except that top and 7 bottom pivot type hinges shall be mounted 29 in. (750 mm) centers, all 1/8 in. (3.2 mm). For the Hing
35、e Over Opening Test for concealed hinges, tab distance shall be set in accordance with the manufacturers instructions. 4.1.4 The test door with the hinges shall be mounted to a solid metal member that simulates the hinge side of the cabinet face frame and the test door shall be able to operate freel
36、y through at least 90 degrees. The hinge shall be aligned and spaced to eliminate hinge bind. 4.1.5 A separate set of hinges shall be used for the Hinge Permanent Set Test, the Hinge Operating Life Test and the Concealed Hinge Over Opening Test. 4.1.6 A dial indicator shall be used to measure vertic
37、al permanent set and vertical sag. This indicator shall be located as shown in Figures 1 and 2 and is identified as Indicator 1 on Figure 2. 4.1.7 When testing Grade 1 hinges, a second dial indicator shall be used to measure horizontal permanent set and horizontal sag. The indicator shall be located
38、 opposite the upper hinge as shown in Figures 1 and 2 and is identified as Indicator 2 on Figure 2. Exception: With top and bottom pivot type hinges, Indicator 2 shall be centered in. (12.7 mm) from the top of the door. 4.1.8 When the hinges to be tested are designed for mounting on a glass door, gl
39、ass thickness for the hinge shall be in accordance with the manufacturers specification. The height and weight of the test door shall be in accordance with 4.1.1 and 4.1.2. 4.1.9 Self closing damper hinges shall be tested to the requirements of this section amending the test method as shown in parag
40、raphs 4.4.2 and 4.4.3. 4.2 Test 1 Hinge Permanent Set Test 4.2.1 Open the door 5 3 degrees and with no weight applied measure the position of the door with the indicators located as shown in Figures 1 and 2. 4.2.2 The specified load (4.2.6) shall be applied to the door as shown in Figures 1 and 3. 4
41、.2.3 Slowly operate the door to a 90 3 degree open position and then return it to the 5 3 degree open position. 4.2.4 Remove the test load and then measure the position of the door as shown in Figure 2. 4.2.5 The difference in measurements made in 4.2.1 and 4.2.4 is permanent set. 4.2.6 Maximum Perm
42、anent Set: Hinge Grade Load - lbf(N) Vertical set in.(mm) Horizontal set in.(mm) 1 160 lbf. (712) .030 in. (0.76) .030 in. (0.76) 2 75 lbf. (334) .060 in. (1.52) - 3 75 lbf. (334) .090 in. (2.29) - 4.3 Test 2 Hinge Operating Life Test 4.3.1 Open the door 5 3 degrees and measure the position of the d
43、oor with the indicators located as shown in Figure 2 4.3.2 Open and close the door at a rate not to exceed 15 cycles per minute with each cycle consisting of opening 90 degrees from the 5 degree open position or completely closed position (all 3 degrees). For Self Closing Damper Hinges, allow the hi
44、nges to completely close the door in each cycle. 4.3.3 Upon completion of cycling, return the door to 5 3 degree position and measure the position of 8 the door. 4.3.4 The difference in measurements in 4.3.1 and 4.3.3 is sag. 4.3.5 Maximum Sag After Cycling: Hinge Grade Cycles Vertical - sag in.(mm)
45、 Horizontal sag in.(mm) 1 100,000 .030 (0.76) .020(0.51) 2 50,000 .030 (0.76) - 3 25,000 .030 (0.76) - 4.4 Test 3 Self Closing Hinge Closing Force Test and Over-Opening Test 4.4.1 In addition to the Hinge Permanent Set Test 1 and the Hinge Operating Life Test 2, self closing hinges shall meet the Cl
46、osing Force Test 3. Frame and frameless concealed hinges shall also meet the Over-Opening Test described in 4.4.4. 4.4.2 At the start of the Hinge Operating Life Test 2, two self closing hinges when mounted on the test door shall produce a minimum closing force (not the force to open) when the door
47、is in the closed position of 4 ounces (1.1 N) 14 inches (356 mm) from the test fixture as specified in Figure 1. For Self Closing Damper Hinges take the closing force measurement before installing the damper mechanism. 4.4.3 After the Operating Life Test 2, the hinges shall hold the door in the clos
48、ed position and the hinges shall cause the door to automatically close from not less than 10 degrees open position while the door is being moved slowly toward the closed position. For Self Closing Damper Hinges the hinges shall hold the door in the closed position with the damper fully engaged, and
49、with the damper removed shall cause the door to automatically close from not less than 10 degrees open position while the door is being moved slowly toward the closed position. 4.4.4 Using a test fixture as described in 4.1 and shown in Figure 3, open the door to the fully open position. Apply a force in the opening direction at a point 12 in. (305mm) out from the inside edge and halfway down the length of the door. Apply the force increasingly at a constant rate up to the required value and the
