Liquid Penetrant Testing (PT) is one of the most widely utilized non-destructive testing methods for detecting discontinuities open to the surface. It is an exceptionally effective control technique for identifying cracks, porosity, surface laps, and localized leakage path problems.
The Penetrant Testing (PT) Training, provided within the framework of EN ISO 9712, is a comprehensive program designed to equip participants with the theoretical principles of the method, application techniques, and evaluation criteria in accordance with international standards.
The primary objectives of this training are to:
Provide a technical foundation in the principles of penetrant testing.
Ensure the accurate detection and identification of surface discontinuities.
Cultivate the competence to perform inspections in compliance with relevant standards.
Enhance evaluation and technical reporting skills.
Establish the knowledge infrastructure required for Level I, II, and III qualifications.
The training encompasses the following technical modules:
The principle of capillary action.
Surface tension and wetting characteristics.
Penetrant types (color contrast / fluorescent).
Developer types and their functions.
Surface preparation and pre-cleaning.
Application of the penetrant.
Dwell time requirements.
Removal of excess penetrant.
Application of the developer.
Final inspection and evaluation.
