The responsible German committee is Working Committee NA 062-08-23 AA "Ultraschallprüfung" ("Ultrasonic testing") at the DIN Standards Committee Materials Testing (NMP). A step wedge calibration block is not meant to check an ultrasonic instrument. A step wedge calibration block makes it possible, during practical testing, to check simply, from time to time, the setting of the time base and the sensitivity of the ultrasonic equipment. Calibration block No. 1 is specified in ISO 2400. Calibration block No. 2 is specified in ISO 7963.
