1. During the test, a uniformly distributed load equivalent to the difference between the rated mass and the tare weight of the container should be placed in the container and fully bolted.
2. The ground on which the offshore container falls should be a flat concrete floor or other hard surface. The ground may be covered with planks, which shall not exceed 50 mm in thickness.
3. Lift the marine container tilted so that the angle between the side beam and the end beam connected to the lowest angle on the bottom of the container and the ground is not less than 5°. On the bottom surface of the container, the height difference between the lowest corner point and the highest corner point should not be greater than 400 mm.
4. During testing, the corner with the worst stiffness should be selected as the lowest impacted corner.
5. The lowest corner point of the offshore container should be more than 50 mm away from the ground. The initial impact velocity of the offshore container touching the ground shall not be less than 1m/s.
6. After testing, the offshore container shall not show significant permanent deformation or damage. Small repairable open welds and deformations are allowed.
TLS will not proceed to the next production step until the marine container has passed the vertical impact test
VERTICAL IMPACT TEST

1 WELDING INSPECTION
Welding inspection of containers, including inspection and NDT.
The whole inspection process runs through the manufacturing process of containers, not limited to the final product, and adjusts production at any time to ensure welding quality.
 
2 LIFTING TEST
In addition to the test required by international container safety convention, our company will also carry out a two-point and four-point lifting test.
The two-point lifting test mainly tests the anti-deformation ability of containers at sea under extreme conditions, and the four-point lifting test mainly tests the carrying capacity of containers at sea. Both tests do not allow permanent deformation of containers at sea during accelerated crane lifting.
 
3 DROP TEST
The main purpose of the drop test is to examine the impact of the lifting and placing of containers at sea to ensure that the cabinet can withstand the damage caused by the impact.
 
4. WATER TIGHTNESS TEST
The container body is sprayed with high-pressure water from all directions, and will be checked in all directions after spraying to ensure that there is no water in it.
