Non-destructive testing. Ultrasonic testing. Characterization and verification of ultrasonic thickness measuring equipment1 Scope This European Standard specifies methods and acceptance criteria for assessing the performance of instruments for measuring thickness using pulse echo ultrasound. This European Standard covers both direct (digital) reading and waveform display types using single or dual element probes. This European Standard may be used for verifying equipment covered by EN 126681, EN 126682 and EN 126683 when used for thickness measurement.
