DIN EN 12668-1:2010-05

This document has been prepared by CEN/TC 138 "Non-destructive testing", the secretariat of which is held by AFNOR (France). At NMP the responsible Committee is Working Committee NA 062-08-23 AA "Ultraschallprüfung" ("Ultrasonic testing") of NMP. This document specifies methods and acceptance criteria for assessing the electrical performance of analogue and digital ultrasonic instruments for pulse operation using A-scan display, employed for manual ultrasonic non-destructive examination with single or twin transducer probes operating within the centre frequency range 0,5 MHz to 15 MHz. Ultrasonic instruments for continuous waves are not included in this standard. This standard may partly be applicable to ultrasonic instruments in automatic systems but then other tests may be needed to ensure satisfactory performance.
