Blasting seismographs are used to establish compliance with Federal, state and local regulations and evaluate explosive performance. Laws and regulations have been established to prevent damage to property and injury to people. The disposition of the rules is strongly dependent on the accuracy of ground vibration and air overpressure data. In terms of explosive performance the same holds true. Developed by the ISEE Standards Committee, this technical guideline for blasting seismographs is intended to improve accuracy and consistency in ground and air vibration measurements. 2015, PDF.
