A prerequisite for ITC Category 2 is that the student must hold a Category 1 certificate.
The five day Category 2 training course prepares you for qualification as a Category 2 certified Thermographer. You will learn about topics in Infrared Thermography to both deepen and broaden your knowledge about infrared physics, heat science, infrared measurement equipment and its application.
As a Category 2 Thermographer you shall provide guidance to category 1 personnel in the areas of equipment selection, techniques, limitations, data analysis, corrective actions and reporting.
In order to attend a Category2 Thermography Course, you shall
• hold a valid Level 1/ Category 1 Thermography certificate,
• prepare a case study to be presented at the Category 2 course and submitted towards qualification at course closing. Details and guidelines on the case study will be issued 2-3 weeks prior to the course start date.
Introduction to Thermography: Review of Level 1 Thermography
Temperature: Conversion factors between Kelvin, Celsius, Fahrenheit.
Heat Transfer Theory: Convection, conduction and radiation – Radiation Laws.
Thermography: Blackbodies, emissivity.Planks, Boltzman, Newton, Wein’s laws
Optical filters, optical materials, anti-reflective coatings.
Atmospheric transmission and attenuation.
Detector technologies and calibration.
IR Measurement Systems Overview: Details of different thermal imaging camera parameters including, NETD, IFOV, MFOV
IR Windows and window materials: Window measurement formulae, spectral transmittance of different materials
Transient Thermographic NDT: Transient Thermographic methods analyzed.
