4. HINGE CYCLE TEST
4.1 Procedure set-up Using the test door described in 3.4.1, mount hinges in accordance with 3.4.2 &3.4.3. Before test, each mounted and loaded specimen shall be accurately measured to determine any vertical or lateral clearance between leaves and knuckles. Measurements shall be taken at mid-travel of door. Angle of opening shall be the same for final measurements as for original measurements within 2 degrees. Vertical measurement is between adjacent jamb and door knuckles. Lateral measurement is between inner edge of jamb leaf and adjacent door knuckle. If the lateral measurement location is at the center of the hinge, one measurement per hinge at the center shall suffice. If the lateral measurement location is not at the center of the hinge, two measurements, as equally distant from center of hinge as practicable, shall be taken; the qualifying 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 4.1 to determine the displacement between leaves and knuckles. Wear is determined as the 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
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. 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 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 period 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.BHMA A156-20 pdf download.
