Test method
Load the loading block (203±13)mm in diameter and 734N in weight in the corner in front of you. If the handrail affects the loading position, remove the handrail. If the handrail is not removable, the loading point should be avoided as far as possible.Slow loading, try to avoid impact on the seat surface. The loading rate was 10 times /min-30 times /min, a total of 20,000 times. After the loading was completed, the load was replaced in the other corner of the front end for 20,000 times.
Conform to the standard
