Application Summary AI generated
GB/T 34885-2017 specifies the general principles for electromagnetic ultrasonic testing (EMAT), a non-destructive method used to detect flaws and measure material thickness in conductive or ferromagnetic components. It is applied in industries such as petrochemical, power generation, and manufacturing for inspecting pipes, plates, and welds where contact with the test surface is difficult or high-temperature conditions exist. The standard provides guidelines for equipment, calibration, and testing procedures to ensure consistent and reliable results in quality control and in-service inspection contexts.
