1、 Purpose:

The XJJ-50 simply supported beam impact testing machine is used to determine the impact toughness of non-metallic materials such as hard plastics, fiber-reinforced composite materials, nylon, fiberglass, ceramics, cast stone, and plastic electrical insulation materials. It is a commonly used equipment for quality inspection in scientific research institutions, colleges and universities, and related factories and mines.

2、 Applicable standards:

ISO179、GB/T1043、JB/T8762
