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 5.1 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:
A-1 CONFORMANCE CRITERIA
Certification that products offered meet the requirements of this Standard and conform to individual manufacturer's drawings, specifications, standards and quality assurance practices are available and in some circumstances are required. Buyer requirements determine the need for proof of conformance such as first article inspection, test laboratory reports, or listings.
