Liquid Penetrant Examination Basics is an online course in which students learn what liquid penetrant (PT) examination is, how it works, and which materials can and cannot be examined using this process. Students are also presented with the requirements found in the ASME BPV Codes of Construction regarding PT examination, including compentency and qualification of personnel, acceptance standards, repair standards, and terminology.

Students are then walked through the detailed steps found in ASME's Section V for performing PT examination: surface pentration, penetrant application,  excell penetrant removal, developer application, interpretation/evaluation of results, and post-examination cleaning. Documentation of examination results and how to ensure your PT site is safe are also reviewed.
