5.2 Initial Vertical and Lateral Hinge Wear Measurement At the start of the testing, the specimen shall be accurately measured to determine any vertical or lateral clearance between hinge 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. V ertical measurement is between adjacent jamb and door knuckles. Lateral measurement is between inner edge of jamb leaf and adjacent door knuckle.If this location is at the center of the hinge, one measurement per hinge at the center shall suffice. If this 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.
5.4 Cycle Test
5.4.1 - Regular Cycle Tests (Grade 1) With the door latched, apply a force to the door, that results in a net 20 to 22 lbf load on the latch(es), approximately 3 in. (76mm) from the latch edge and 40 in. (1020 mm)from the floor in the direction of the door swing until the door is opened. The force shall be applied using weights. Each cycle shall include the unlatching of the hardware from the egress side, opening the door from the egress side to 60 degrees, releasing the door, and latching the door. For exit devices, the opening force shall be applied to device itself. For all other trim the opening force shall be applied to the face of the door at hardware height. For all configurations the force shall be applied continuously rather than throwing the door open. The minimum closing speed shall be three seconds. Rotate levers and knobs in one direction only until the total cycles have been met for the grade being evaluated.
5.4.2 Regular Cycle Tests (Grade 2) No door preload requirements for Grade 2
Each cycle shall include the unlatching of the hardware from the egress side, opening the door from the egress side to 60 degrees, releasing the door, and latching the door. For exit devices, the opening force shall be applied to device itself. For all other trim the opening force shall be applied to the face of the door at hardware height. For all configurations the force shall be applied continuously rather than throwing the door open. The minimum closing speed shall be three seconds. Rotate levers and knobs in one direction only until the total cycles have been met for the grade being evaluated.BHMA A156-32 pdf download.
