6、ithout specific authorization from BHMA Printed in the USA This Standard was approved by ANSI under the Canvass Method. The Builders Hardware Manufacturers Association, Inc. was accredited on 21 March 1983 by ANSI as a sponsor using the canvass method.3 FOREWORD (This Foreword is not a part of ANSI/

7、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 Standard is the

8、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 will be found, it

9、ems 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. Grade classificatio

10、ns 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 are not intended

11、 to be used without necessary supplementary information. Individual manufacturers catalogs are consulted. 4 TABLE OF CONTENTS 1. SCOPE. 5 2. DEFINITIONS. 5 3.

12、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 4.1 to determine the displacement between leaves and knuckles. Wear is determined as the difference betwe

13、en 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: 7 4.3 Requirements Cycle Test Requirement

14、s Vertical and Lateral Wear Allowable Maximum Bearing Grade 1 Grade 1 Grade 2 .010 inches (.25 mm) .020 inches (.5mm) .030 inches (.75 mm) 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 mm) when tested in

15、 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. 5.4 Open and close

16、 door. Open the door to the 90 degree open position and return to the closed position. 5.5 Remove the test weight. 5.6 Re-measure 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 lateral shift). 6.

17、 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, except key locking type, shall be fastened with a padlock having a shackle with a nominal diameter of

18、0.250 in (6.4 mm). 6.2 Fixed or Adjustable Staple Torque Resistance 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 peri

19、od of 30 seconds. If staple opening does not accommodate both padlock hasp and torque rod, torque shall be applied by inserting torque rod through locked padlock shackle throat. Grade 1 Grade 2 Grade 3 3000 lbf-in (339 Nm) 480 lbf-in ( 54 Nm) 125 lbf-in (14Nm) 6.2.2 After application of the required

20、 torque, the padlock shall continue to be secured to the staple and the staple to the hasp leaf preventing disengagement of the hasp. 6.3 Fixed, Adjustable, Swivel Staple, Staple Rotating Post, or Latching Post Pull Resistance 6.3.1 A load dynamometer shall be applied to load the staple or post perp

21、endicular to the mounting surface. The force shall be applied gradually and be sustained for a period of 30 seconds. Grade 1 250 lbf (1112 N) 6.3.2 After the application of the required load, the hasp shall still be functional. 7. PERFORMANCE REQUIREMENTS FOR FINISHES 7.1 Application. This test appl

22、ies to all products treated by plating or painting. 7.2 Salt Spray Test. This test shall be conducted in accordance with ANSI/BHMA A156.18-2016 for Materials and Finishes. Finishes shall withstand exposure for 24 hours. 8 8. EXPLANATION OF NUMBERING SYSTEM 8.1 The first letter denotes the BHMA Produ
