This part of GB/T 18029 specifies the structure of test dummies with nominal masses of 25kg, 50kg, 75kg and 100kg used in other parts of GB/T 18029. The design principle of the test dummy is to place it on the corresponding wheelchair to be tested, and the position of its center of gravity in the test state is roughly the same as that of a person of the same mass sitting in a wheelchair.
