Intermediate Check on PTM2300-D1 Metal Pendulum Impact Testing Machine

Factors affecting the accuracy of metal pendulum impact testing machine were introduced. Through selecting appropriate intermediate check method, the intermediate check plan for a PTM2300-D1 metal pendulum impact testing machine was developed. The intermediate check, and analysis and evaluation on the check results of the equipment were completed effectively, and the accuracy of the equipment in the metrological verification periodicity was guaranteed.
