MODEL XJJ-5

DIAL TYPE SIMPLE BEAM CHARPY IMPACT TESTER

 

Introduction

 

      This XJJ-5 dial type simple beam impact tester is mainly used for the determination of impact toughness of non-metallic materials such as hard plastics, reinforced nylon, glass fiber reinforced plastics, ceramics, cast stone, electrical insulation materials, etc. It is an ideal testing equipment for chemical industry, scientific research institutions, colleges and universities, quality testing and other departments.

 

      The main technical parameters of XJJ-5 simple supported beam impact tester fully comply with the provisions of ISO 179, GB/T 1043, GB/T 2612, JB/T 8762 and GB 4742 standards, which are applicable to GB/T 1043 and GB 4742 impact test for various samples (including those with and without notches in machining and injection molding), including four spans of 40mm, 60mm and 70mm. When different jaws are replaced and the jaw seat is adjusted, various impact tests can be conducted. It is a simple structure, convenient operation, accurate data and reliable testing instrument. The impact energy of the instrument is 1J, 2J, 4J and 5J.
