The growing importance of ultrasonic testing has persuaded associations for the application of non-destructive testing methods, of manufacturers and users, as well as standardizing organizations, to publish standards ranging from non-compulsory recommendations to specifications with legal status. In every country national standardizing commissions are investigating the specifications proposed by the various associations and societies. In the Federal Republic of Germany this is the DNA (Deutscher NormenausschuB) which publishes the DIN standards. On an international scale the ISO (International Organization for Standardization) is making efforts to reconcile and harmonize the standards of the various countries. For the same purpose on a european scale the CEN in Paris has been established (European Standards Committee). In addition, similar efforts are being made by international professional associations, e.g. in the field of welding, such as the IIW (International Institute of Welding).
