2、NDARD 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 American National Standard does not in any re
3、spect 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 are cautioned to obtain the latest editions.
4、CAUTION NOTICE: This American National Standard may be revised or withdrawn at any time.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. Purchasers of Americ
5、an National Standards may receive current information on all Standards by calling or writing the American National Standards Institute.

7、) 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. Closer Holder Release Devices is one such section and this Standard is the result of the
8、collective efforts of members of the Builders Hardware Manufacturers Association, Inc., who manufacture these products. The total Product Standards effort is, therefore, a collection of sections, each covering a specific category of items. The BHMA recognizes that errors will be found, items will be
9、come 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. The BHMA numbers which indicate type of hardware do not identify size, finish or design and are not intended to be used
10、 without necessary supplementary information. Users of this Standard who require a specific design for a product type describe it using generic terms or the manufacturers name and description desired. 4 TABLE OF CONTENTS 1. SCOPE 5 2.

Test on test door with closer installed. 5.3.7 5. PERFORMANCE TEST REQUIREMENTS 5.1 Initial Static Tests 5.1.1 Two Speeds of Closing Setup: With
35、 the power turned off, adjust the general speed regulating control for a normal closing motion and fully open the latch speed regulating control. Test: Open the door to about 45 degrees and release. The point at which the door noticeably accelerates shall be between the 12 in. (305 mm) and 2 in. (51
36、 mm) marks. Test #2 (Optional): (Permitted in lieu of Test 1 for floor or overhead concealed type closers at option of manufacturer.) With closer adjusted to a closing speed of 4 to 6 seconds from 90 degrees, open the door to 30 degrees and release. The closing force shall exceed the 5 lbf minimum c
37、losing force by at least 30%. 5.1.2 Adjustable Closing Speed Setup#1: With the power turned off, fully close general and latch speed regulating control(s). Test #1: Open the door to 90 degrees and release. Door shall take 60 seconds or longer to fully close. Setup #2: Fully open general and latch sp
38、eed regulating control(s). Test #2: Open the door to 90 degrees and release. Door shall fully close in 3 seconds or less. 5.1.3 Break-in Cycle Test Setup: Mount door closer on test apparatus (see appendix for typical device), regulate door closing time from 90 degrees to between 4 and 6 seconds. Mai
39、ntain this time during cycling by re-regulating if necessary. Fully open backcheck control, where applicable. 8 Test: Cycle door closer to 4,000 cycles. 5.1.4 Closing Force Test Setup: With the power turned off, open the speed regulating control(s). In closers with adjustable spring power, set closi
40、ng power to the closest increment equal to or greater than 5 lbf (22 N). Test: Open the door beyond the 3 in (76 mm) line. Holding the door with a force gauge allow the door to close slowly under the power of the door closer as the door travels between the 3 in (76 mm) and in (12.7 mm) marks and rec
41、ord the force. It shall equal or exceed 5 lbf (22 N). 5.1.5 Door Closer Efficiency Test Setup: Mount door closer and fully open the general and latch speed regulating controls with the power turned off. Test: First, using a force meter open the door slowly and uniformly. Record the opening forces F3
42、, F4, and F5 as the door edge passes the 2 in. (51 mm), 3 in. (76 mm), and 4 in. (102 mm) marks respectively. Second, starting beyond the 4 in. (102 mm) mark, let the door closer close the door in a slow and uniform manner resisted by the force meter. Record the force readings F6, F7, and F8 as the
43、door edge passed the 4 in. (102 mm), 3 in. (76 mm), and 2 in. (51 mm) marks respectively. Calculate the door closer efficiency by the following formula: Percent Efficiency = (F6 + F7 + F8) / (F3 + F4 + F5) x 100 Door closer efficiency shall be a minimum of 60%. 5.1.6 Force Test Setup: The door shall
44、 be equipped with a size 4 closer, or size 3 for track arm installations only, and held open at the 90 degree position. The holding mechanism shall be energized at the rated power. Test: The force required to release the door manually shall not exceed 40 lbf (178 N) when measured 30 in (762 mm) from
45、 the hinge centerline. 5.1.7 Creep Test Setup: With the holding mechanism energized, open the door to the 90 degree hold-open position and scribe a mark measured at 30 in (762 mm) from the pivot point along the door edge. Test: After 24 hours, the door shall not have moved more than in (12.7 mm). 5.
46、2 Cycle Test Setup: When testing other than free swinging release devices, regulate the door closing time from 90 degree opening to between 4 and 6 seconds. Maintain this time during cycling by re-regulation. Readjust hold-open during cycling as necessary. (When free swinging release devices are bei
47、ng tested, the door closing time shall not be faster than 4 seconds.) Test #1: Mechanically open the door to 90 degrees and after 2 to 5 seconds release power from hold-open, allowing the door closer to completely close the door. One opening and closing constitutes one cycle. Repeat this action for
48、25,000 cycles. Free swinging release devices shall be cycled 100,000 cycles. 9 Test #2: Mechanically open the door to 90 degrees and after 2 to 5 seconds mechanically release from hold-open, allowing the door closer to completely close the door. One opening and closing constitutes one cycle. Repeat
49、this action for 50,000 cycles. (Not applicable for free swinging release devices.) Test #3: Mechanically open the door to 90 degrees and after 2 to 5 seconds release power from hold-open, allowing the door closer to completely close the door. One opening and closing constitutes one cycle. Repeat this action for 25,000 cycles. (Not applicable for free swinging release devices.) 5.3 Final Static Tests 5.3.1 Adjustable Closing Speed Setup#1: With the power turned off, fully close general and latch speed re
