WebbDisadvantages of rebound hammer test. The disadvantages are that the results obtained are based on a local point and it is not directly related to the strength and the deformation property of the surface. The spring and probe arrangement will require regular cleaning and maintenance and the flaws cannot be detected with accuracy. is storing data classed as processingWebbWhen performing a Schmidt Hammer Test, it is critical that the hammer be held at right angles to the surface. The orientation of the Hammer will in turn affect the rebound reading, and different calibration curves are required by orientation. Original Schmidt Type NR/ LR.
