Original Abstract

The paper contains a brief description of the current state in our calibration facility for the acoustic emission sensors. We have implemented the reciprocity method according to the NDIS 2109, ISO/TR 13115, using the step function according to ASTM 1106, ISO 12713 and the longitudinal wave calibration according to NPL. The greatest attention is given to problems relating to the correct implementation of AE sensor calibration methodology. It describes in detail influence of the aperture effect on the frequency response to the Rayleigh wave calibration of a wideband sensor. Briefly described is the basic principle and design of a wideband AE sensor with a conical active element and frequency characteristics of our reference sensors are specified as obtained from all types of absolute calibration for the surface waves and longitudinal waves.
