This standard specifies the classification, technical requirements, test methods, inspection rules and marking, packaging, transportation, storage, etc. of foundation pile dynamic test instruments. This standard is applicable to the structural integrity of the pile body of engineering foundation piles and the vertical bearing capacity of single piles (axis in the case of inclined piles) using the low strain or high strain methods specified in the current standards JGJ/T 93-1995 and JGJ 106-1997. A measurement and analysis instrument for dynamic testing of bearing capacity).
