The goal of the four-day Level III training course is to enable the Level II thermographer to set up and run a successful condition monitoring thermography program. As such, the course provides guidance for acquiring and developing the necessary people, resources and technologies.
Learning Objectives
By the completion of this course, the participant will be able to:
- Define infrared thermography.
- Explain the three modes of heat transfer.
- State where infrared energy fits into the electromagnetic spectrum in relation to visible light.
- Identify the elements of conduction heat transfer and their effect on heat transfer rates.
- Compare and contrast meanings of the terms: range, level, and span.
- Describe how the intensity of emitted IR from a surface changes with temperature.
- Identify the elements of conduction heat transfer and their effect on heat transfer rates.
- Explain the difference between total radiation and emitted radiation.
- Identify a conduction thermal pattern.
- Describe the relationships between emissivity, reflectivity, and transmissivity.
- Explain how emissivity and reflectivity can affect the IR image and temperature readings.
- Identify safety requirements for thermographers and accompanying personnel for IR surveys.
- Name the following standards organizations and explain their respective roles in the field of thermography:
- ASNT
- BINDT
- ISO
- ASTM
- NFPA
- Explain the process you would use to create an IR procedure for your own organization
- Explain the process you would use to create an IR thermography budget for your own organization
- Develop a written practice for Level I, Level II and Level III thermographers
Hands-on work is emphasized with six labs including heat transfer, IR window transmissivity measurement, emissivity cavity effect, written practice and problem severity criteria development. The course includes several Excel-based software programs making it easy for the student to calculate heat loss from a surface, calculate load correction, estimate avoided costs, estimate energy savings based on improving building wall R-Value, develop an equipment condition status report and develop a program budget.
Certification
The learning objectives, contact hours, and written exam of Level III course are based on the recommendations outlined by ANSI/ASNT CP-105 and CP-189 of the American Society for Non-Destructive Testing. As such, this course is suitable for use by your employer to certify you under ASNT’s Recommended Practice No. SNT-TC-1A provided it is consistent with your employer’s written practice.
Prerequisites
A course completion certificate from a Level II thermography course is required to be a Level III student. Camera Training Our instructor led training classes only cover basic camera operation. We highly recommend you take one of our online web courses for your specific camera before coming to class. Please note online training may not be available for some camera models.
