The Penetration Non-Destructive Testing Engineer Past Exam Summary App is a problem-solving and summary study app designed for students preparing for the written exam.

Penetration testing is an inspection method that utilizes the capillary action of a penetrant to detect discontinuities, such as cracks, pores, and overlaps, that have opened on the surface of a test specimen. In this app, you can learn step-by-step, ranging from the basic principles of penetration testing to detailed criteria frequently tested in actual exams.

The main learning content is as follows:

Principles and Scope of Application of Penetration Testing

Wetting properties, contact angle, surface tension, and viscosity of penetrants

Characteristics of fluorescent and dye penetrants

Inspection methods for washability, post-emulsification, and solvent removal

Sequence of pretreatment, penetration treatment, emulsification treatment, and washing treatment

Dry, wet, fast-drying, and no-development methods

UV irradiation intensity and white light observation conditions

Classification of linear, circular, continuous, and dispersed penetrant indications

Type A and Type B comparative test specimens

Management of penetration time, emulsification time, and development time

Standards related to KS B 0816

Inspection conditions related to ASME Sec. V

Preparation of inspection reports and safety management

Calculation problems related to chlorine and sulfur content

Each problem includes the correct answer and explanation, allowing you to immediately identify the cause of incorrect answers. Through repeated study, you can naturally memorize frequently tested figures and inspection procedures.

This material is suitable not only for students preparing for the Penetration Non-Destructive Testing Engineer exam for the first time but also for learners who wish to quickly review key content right before the exam.
