The third edition of ASNT Level III Study Guide: Liquid Penetrant Testing provides prospective ASNT Level III examinees with a review of the technical knowledge for an ASNT Level III exam. It is intended to be used with a comprehensive NDT text, such as ASNT’s Nondestructive Testing Handbook, Vol. 1: Liquid Penetrant Testing, fourth edition. This edition was updated to reflect the most current information on PT as outlined in CP-105, with new and expanded content and new figures. All chapter review questions are multiple-choice, with four unique answers to more closely match the ASNT exam format.
