Grouting recorder is an instrument to measure and record the real-time parameters of cement grouting process. It's an important means to control grouting process and to ensure  project quality. It has been widely used in the foundation grouting in China's water conservancy and hydropower engineering. However, the instrument is not yet included in the supervision and management of China's legal metrology, hence the product quality and the metrological characteristics are in lack of single standard, which affects the application effect and the sound development of the product market. On the basis of related standards and regulations, we proposed the contents, principles, and methods of grouting recorder calibration in line with engineering practices. The research provided basic idea for  formulating  calibration standard for grouting recorder.
