- Mar 16, 2018 -

Summary

 The Impact Test Steel Ball is mainly used to determine the shell mechanical strength of appliances. The shells of the appliances should be sure that it can not appear the danger within the scope of the standard ranges when operating.it is suitable for the appliances which surfaces of shells are damaged and will contact with the hazardous parts, and also suitable for testing  mechanical strength of glass,PVC ,ceramics and so on.
