Category 2 Thermography ISO18436

ITC offers certification training to recognised standards and is an accredited Authorised Training Organisation (ATO) for the British Institute of Non Destructive Testing (BINDT) as per the requirements of ISO 18436


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.
