GB/T 14123-2012 focuses on the performance characteristics of mechanical Impact Testers. The standard specifies the type of testing machine, elaborates on key performance parameters such as Impact pulse waveform and peak Acceleration, and specifies the Measuring method and accuracy requirements for these parameters. There are also relevant regulations on the structural design, operation convenience and safety protection of the testing machine. Through the specification, it provides unified guidelines for the production, calibrating and use of mechanical Impact Testers to ensure the reliable performance of the testing machine, and can accurately simulate the Impact environment in the impact testing of materials and parts to ensure the accuracy of test results.
