DB31/T 1200-2019 Technical specification for the inspection of concrete defects by phased-array ultrasonic imaging testing method
This standard specifies the terms and definitions, general provisions, on-site detection, and detection reports for the detection of concrete defects using phased array ultrasonic imaging.
This standard is applicable to the qualitative detection of concrete defects in concrete components (hereinafter referred to as components) with a detection surface parallel to the ultrasonic reflection surface, including the detection of internal concrete defects and defects at the interface between new and old concrete.
