摘要
The main parameters of calibration blocks for ultrasonic testing that must be measured during metrological certification are considered: the geometric dimensions of reflectors, the velocity and attenuation of elastic waves, etc. A method for measuring the damping factor is proposed that simplifies the measurement procedure. A form of the certificate registered officially for calibration blocks that were subjected to metrological certification is presented.
