The IK protection level test is divided into 10 levels. We divide this 10 level test level into two groups of tests:
The first group is the spring impact hammer test from IK01, IK02 to IK06, the energy of this group of tests is relatively small (from 0.14J to 1J);
The other group is the big pendulum test from IK07, IK08 to IK10, and the test energy is larger (ranging from 2J to 20J)
