摘要

In 2011, the American Society for Nondestructive Testing's (ASNT) journal, Material Evaluation, pub-lished the 2011 ASNT Annual Business Meeting Minutes. As of this year ASNT is celebrating its 70th year as an organized society. ASNT published its first edition of a recommended practice in 1967 for the qualification and certification of nondestructive testing personnel. Currently, there are 5,726 indi-viduals holding 15,829 ASNT NDT Level III certificates.l Employers have certified many thousands more in accordance with employer based written practices that meet ASNT's recommended guidelines. Many other organizations have derived similar programs but with third party or central agency admini-stration. They all contain essentially the same six elements.
