Store description excerpt
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.
