31、ection level of 5-2, AQL of 2.5 percent defective for major defects. Service test. A reciprocating drive device shall be attached to the top center of the stand. The attachment shall allow the stand to rotate freely on its vertical center axis. Distribute 45.3 kg evenly on the top of the stand. Plac

32、e the stand on the obstacle layout detailed in figure 1. The device shall push the stand 762 mm forward and pull it 762 mm backward over the obstacles, continuously at a rate of 10 to 15 cycles per minute for 10,000 cycles. One cycle is a forward and backward stroke. Any structural breakage, looseni

33、ng or deformation of parts which affects the stability or serviceability of the stand or any change which could cause personal injury to a user shall constitute failure of the test. 4.7 0 4.8 Test of top levelness, deflection, and rigidity. The castors shall be removed. A straight edge shall be plac

34、ed diagonally (corner to corner) across the unit top. The straight edge shall extend beyond the corners. Any warp of the top in excess of 0.78 mm is cause for rejection. This test shall be performed across both corner diagonals. Upon satisfactory completion of the above test, a weight of not less th
