AMERICAN NATIONAL STANDARDS INSTITUTE Approved November 28, 2012 2 AMERICAN NATIONAL STANDARD An American Nation

2、al 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 respect preclude anyone,

3、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. CAUTION NOTICE: This Am

4、erican National Standard may be revised or withdrawn at any time.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. Publishers of American National Standards m

5、ay receive current information on all Standards by calling or writing the American National Standards Institute.

7、t a part of ANSI/BHMA A156.20) 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. Strap and Tee Hinges, and Hasps is one such section and this

8、 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 items. The BHMA recognizes that errors

9、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. In most cases, products have been described in grade levels related to their durability. Gr

10、ade classifications indicate levels only within their own product categories. Choice of grade and specific product are made on the basis of utility, aesthetics, security objectives and end use desired. The BHMA numbers which indicate types and functions of hardware do not identify size or finish and

11、 are not intended to be used without necessary supplementary information. Individual manufacturers catalogs are consulted. 4 TABLE OF CONTENTS 1. SCOPE. 5 2. DEFINITIONS. 5 3.

12、alifying lateral measurement is the average of these two. 4.2 Cycle Test Cycle the hinges through 90 degrees for 100,000 cycles At the conclusion of the cycle testing, each specimen shall again be measured as in 5.1 to determine the displacement between leaves and knuckles. Wear is determined as the

13、 difference between final and initial measurements. Record measurements of wear for all hinges. The measurements of the greatest wear shall be compared to the permissible figures. The hinges passing the test shall comply with the vertical and lateral wear requirements below: 4.3 Requirements Cycle T

14、est Requirements Vertical and Lateral Wear Allowable Maximum Bearing Grade 1 Grade 1 Grade 2 .010 inches (.25 mm) .020 inches (.5mm) .030 inches (.75 mm) 7 5. HINGE PERMANENT SET TEST PROCEDURE & REQUIREMENT 5.1 Lateral shift. The lateral shift of doors away from jamb shall not exceed .060 in (1.5 m

15、m) when tested in the following manner. 5.2 Door position. Measure the horizontal position of the door at the top hinge, using the dial indicator, with the door in the closed position. 5.3 Add test weight. Add the test weight, as indicated in the chart for the hinge, at the outer edge of the door. 5

16、.4 Open and close door. Open the door to the 90 degree open position and return to the closed position. 5.5 Remove the test weight. 5.6 Remeasure door position. Measure the horizontal position of the door as in 5.2. The difference between the two measurements is the horizontal set of the door (or la

17、teral shift). 6. STRENGTH TEST FOR HASPS 6.1 Mounting. The hasp shall be mounted in the closed position on a steel plate using machine screws of a size equivalent to the fasteners provided with the hasp. The hasp shall be fastened with a padlock having a shackle with a nominal diameter of 0.250 in (

18、6.4 mm). 6.2 Fixed Staple Type 6.2.1 A torque measuring device shall be applied to the staple in a plane parallel to the mounting surface. The torque shall be applied gradually using a nominal 0.375 in (9.5 mm) diameter hardened steel rod and sustained for a period of 30 seconds. If staple opening d

19、oes not accommodate both padlock hasp and torque rod, torque shall be applied by inserting torque rod through locked padlock shackle throat. 6.2.2 After application of the appropriate minimum torque, as indicated below, the padlock shall continue to be secured to the staple and the staple to the has

20、p leaf preventing disengagement of the hasp. Fixed or Adjustable Staple Torque Resistance Grade 1 Grade 2 Grade 3 3000 lbf-in (339 Nm) 480 lbf-in ( 54 Nm) 125 lbf-in (14Nm) Swivel Staple, or Staple Rotating Post, or Latching Post Pull Resistance Grade 1 250 lbf (1112 N) 6.3 Swivel Staple and Rotatin

21、g Post Types 6.3.1 A load dynamometer shall be applied to the swivel staple or rotating post to load the staple or post perpendicular to the mounting surface. 6.3.2 After the gradual application of a 250 lbf (1110 N), the hasp shall still be functional. 7. PERFORMANCE REQUIREMENTS FOR FINISHES 7.1 A

22、pplication. This test applies to all products treated by plating or painting. 7.2 Salt Spray Test. This test shall be conducted in accordance with ANSI/BHMA A156.18-2012 for Materials and Finishes. Finishes shall withstand exposure for 24 hours. 8 8.
