, after evenly distributing the bacterial load selected by the product standard on the cabinet (or rack), check the geometric deformation of each place, and then cancel the load to check whether each place has returned to its original state before the load. After adding the load again, lift the cabinet (or frame) with the same length of the four rings and the top of the sensor frame at 55*5*, and then hang it for 10 minutes to check the deformation of each place. Finally, lift the cabinet (or frame) at both ends of the opposite corners, and then hang it for 1m to check the deformation of each place. After comprehensive inspection, it should still meet the size requirements specified in the design drawings. The static load test of the 7.5 plug-in box is uniformly distributed on the blue box. The static load (or insert the "matching plug-in" for testing) sheet selected by the standard is statically loaded for 4 hours to check the deformation of each place. After consideration, cancel the load and check whether each place has returned to its original state before the load. After adding the load again, lift the temporary box with the handle, and then put it down after 10 minutes to check the deformation of each place. After unloading, it still meets the size requirements specified in the design drawings. 7.5.1 The dynamic load test method for structures such as cabinets, racks or plug boxes shall comply with the provisions of GB2423.10 and GB2424.7. 7.5.2 The free fall test method for structures such as cabinets, racks or plug boxes shall comply with the provisions of GB2423.8 and GB2424.6: 7.6 Electrical connection performance test
