The standard "GB/T 33888-2017 Nondestructive Testing Instruments, Ultrasonic Thickness Gauges Characterization and Verification" specifies the methods and acceptance specifications used to evaluate the performance of pulsed echo ultrasonic thickness gauges. The standard covers both direct reading and waveform display types of ultrasonic thickness gauges, supporting single or dual-crystal probe applications. It is suitable for the verification of thickness measuring equipment in the GB/T 27664 series of standards. The general requirements that the instrument should meet are described in the text, including clear requirements for technical specifications, certification statements, product identification, and performance indicators. This standard aims to ensure that the performance and mass of ultrasonic thickness gauges meet industry standards and improve the accuracy and reliability of testing.
