This standard specifies the uniform requirements for the design, production, test methods and inspection rules of differential resistance strain gauges (hereinafter referred to as strain gauges) embedded in concrete buildings. This standard applies to strain gauges buried in concrete buildings. Strain gauge is a sensor for long-term measurement of internal strain of concrete buildings and can also measure temperature.
