And Examination Requirements Listed In Section V, Article 1, Mandatory Appendix II for CR, DR, PAUT and TOFD PG-25.2.4 and PW-50 were revised so the mandatory training, experience, and examina-tion requirements listed in Section V, Article 1, Mandatory Appendix II that must be incorpo. The liquid penetrant testing in ASME standards refers to the ASME Code Section V Article 6, and it addresses the different methods and technique and corresponding requirements. The requirements include to the cleaning methods, penetrant dwell time, developer dwell time, liquid penetrant material specification, test object temperature.

The liquid penetrant testing code refers to ASME CodeSection V article 6 for performing the test. This code section providesrequirements for liquid penetrant testing Personnel qualification, writtenprocedure requirements, liquid penetrant test techniques and process and itsrelated requirements, penetrant and developer dwell time requirement, liquidpenetrant testing equipment calibration requirements and etc. The code sectionguides how to perform the test and what requirements shall be followed.

Liquid Penetrant Testing Code for Acceptance Criteria

ASME Code section V article 6 does not provide theacceptance criteria. For acceptance criteria, you should refer to correspondingmanufacturing code.

For example, if you are going to perform a liquid penetranttest on power piping girth weld, the acceptance criteria can be found on theASME B31.1, or you want to perform a liquid penetrant test on process piping,then you need to refer to the ASME B31.3. Please note, an indication might be considered as a defect by aconstruction code, but the same indication not considered a defect by anothermanufacturing code.

The test always shall be performed based on approvedprocedure. The procedure is typically prepared and approved by an ASNT LevelIII and conducted by a level II technician.

Other Liquid Penetrant Testing Code

The other considered as standard and not code. The verbiageof code is used when mandated by a government or authority. For example in thestate of California, designing and manufacturing of pressure vessel shall bebased on ASME Code. Then automatically, requirements of the ASME Section Varticle 6 for liquid penetrant testing is a requirement by law (when is appliedto pressure vessel)

The other common standard is:

There are hundreds of other standard and specification inthe market for performing and evaluating the result of liquid penetranttesting. Each industry has own codes and standards.

For instance, Society ofAutomotive Engineers International have SAE AMS 2644 (Inspection Material,Penetrant), SAE AMS 2647B (SAE AS 3071A), SAE AMS 3161A (Oil, Odorless HeavySolvent), SAE AS 3071A (Acceptance Criteria Fluorescent Penetrant) and SAE J426 (Liquid Penetrant Test Methods, Information Report)
