The digital display drop weight tear test machine is mainly suitable for the drop weight tear test of ferritic steel. The free fall of the hammer impacts the sample, causing the sample to break, and the impact is completed to observe the morphological characteristics of the fracture of the sample. Replacement of accessories can also perform drop hammer tear test and result evaluation on metal parts or components, and can obtain impact energy, impact height, and impact time.
It meets the technical requirements of GB/T 8363-200 "Ferritic Steel Drop Weight Tear Test Method", and refers to ASTM E436-80 "Ferritic Steel Drop Weight Dynamic Tear Test Standard Method" and API 5L3-96 "Pipeline Test methods such as Recommended Practice for Pipe Falling Weight Tear Test.
