4.1.3 Cycle Test
Mount the holder on the test door in accordance with the manufacturer's instructions. Cycle the holder at a rate of six to ten cycles per minute with an impact of 7 lbf-ft (9.5 J) at a point 4 in (102 mm) from the bottom of the door and 8 in (203 mm) inward from the free swinging edge of the door. Manual hook and eye types are exempt from the operation of the hook in the eye. Cycle lever and lever types without impact. At the end of the test, all functions shall be operable.
4.2.1.1 Cycle Test Perform the cycle test using the test fixture listed in 4.1.1 and Door Ram Pendulum System specified in ASTM F476-84 (2002). Mount and impact door stops in accordance with 4.2.1.2 to the values given in 4.2.3.
4.2.1.2 Impact Test Perform the impact test using the test fixture listed in 4.1.1, the Door Ram Pendulum System, and Body Impact Test Method as specified in ASTM F476-84 (2002) and modified herein. Instead of the impact buffer specified in ASTM F476-84 (2002) use a 1/4 in (6.4 mm) steel plate 8 in (203 mm) square centered at the specified impact point and affixed to the face of the test door with four screws minimum. Attach the door stop to the Mounting Test Fixture A (Figure 7) and normal to the inside face of the test door located as specified. Stops shall be mounted with the resilient face of the stop resting against the closed test door and centered 8 in (203 mm) inward from the free swinging edge of the door.Using the Door Ram, impact the closed door at a point 4 in (102 mm) up from the bottom and 8 in (203 mm) inward from the free swinging edge of the door. Mount wall stops at the level of the center hinge and floor stops on the base plate. Adjustable hinge pin type stops shall be mounted on top hinge of the test door and adjusted to restrain the door at 75±3 degrees when the resilient tip is resting against Bracket B (See Figure 7). Using the Door Ram, impact the closed door at a point 12 in (305 mm) from the bottom and 8 in (203 mm) inward from the free swinging edge of the door.
4.4.1 Load Test Apply a static load on the arm of the test product which has been mounted to a rigid test fixture using fasteners recommended by the manufacturer. The load shall be parallel to the mounting surface and shall be applied for 1/2 minute by a 2 in (50.8 mm) wide leather or canvas strap centered on the end of the arm being tested. Test each arm of a multiple arm product separately. Failure is breakage,disassembly or a 1/2 in (12.7 mm) vertical deflection of the product's arm.BHMA A156-16 pdf download.
