This study guide is intended to aid candidates preparing for the ASNT NDT Level III Basic examination and can also be useful for individuals preparing to take a Basic Level III examination under their employer’s program. The content and sample questions have been updated to reflect the 2020 editions of SNT-TC-1A, CP-189, and CP-105. Included are inquiries and responses from ASNT’s SNT-TC-1A Interpretation Panel for in-depth understanding.

An extensive section is devoted to the general application of 11 different NDT methods, including topical outlines from the 2020 edition of CP-105, references, and method-specific questions and answers. This book also includes entire sections from both SNT-TC-1A and CP-189 instead of excerpts as in previous editions.

In Section III, questions have been reorganized to reflect the chapter sequence in the second edition of ASNT’s Materials and Processes for NDT Technology. Appendixes detailing the Code of Ethics for Level III NDT Personnel Certified by ASNT, the ASNT NDT Level III Program, and tables of common units used in NDT are also included.
