2、 Rough handling test

Mobile ME equipment and its moving parts should be able to withstand the stress generated by rough handling and movement, and should not pose unacceptable risks. Verify compliance with requirements through the following tests. The sample shall be tested under any appropriate safe working load and the most adverse conditions allowed for normal use in the transport posture. During the experiment, appropriate preventive measures should be taken to avoid imbalance caused by rough handling stress or impact.

The experiment is as follows:

a)Door frame impact

The sample moves along the normal direction of motion at a speed of 0.8m/s ± 0.1m/s, or at a speed that can be maintained by a motor-driven moving ME device. It impacts a hardwood obstacle with a thickness and width of 40mm that is resting on a vertical hard support three times. The height of the vertical hardwood obstacle must be higher than the impact point of the ME device, and the direction of motion must face the obstacle vertically. After each experiment, any sustained damage that results in an unacceptable risk will fail the test.

Note 1: Refer to the compliance criteria in 15.3.1.

b)Step up impact

Push the sample to move along the normal direction of motion at a speed of 0.8m/s ± 0.1m/s, or for a motor-driven moving ME device, move it at a speed it can maintain, causing it to collide with a sturdy hardwood obstacle firmly fixed at a height of 40mm on a horizontal ground three times. The direction of travel is perpendicular to the obstacle. The sample does not need to cross a 40mm obstacle.

c) Step down impact

The sample is moved along the normal direction of motion at a speed of 0.8m/s ± 0.1m/s, or for motor-driven moving ME equipment, at a speed it can maintain, and pushed down three times from a 40mm high vertical step fixed on a hard foundation (such as concrete). Vertical descent of the step surface in the direction of motion. During the descent step impact test, if components other than the casters come into contact with obstacles before the casters touch the ground, continue to push the ME equipment until it descends.

Note 2: When the ME equipment remains undamaged after rough handling due to impact/stress, its stability shall be evaluated according to 9.4.

3、 Equipment usage

The ME equipment and its moving components used for inspection should be able to withstand the stress generated by rough handling and movement, and should not pose unacceptable risks.
