- This page details the objectives and guidelines for a Thermography Level I practice exam aimed at improving students' practical skills and confidence. It focuses on equipment setup and essential principles, while encouraging objective language and a process-oriented approach. Successfully completing the exam signifies that students meet the Thermography Level I standards.
- 21.2: SECTION 1- Equipment Setup and Pre-Inspection Verification
- This page emphasizes the importance of verifying focus and temperature range before thermographic inspections to ensure the accuracy and clarity of thermal images. Proper focus captures detailed measurements, while an appropriate temperature range allows for effective display of temperature variations. Such preparation is crucial for reliable data and successful inspection results.
- 21.4: SECTION 3- Handheld Thermal Image Acquisition
- This page covers the inspection of electrical, mechanical, and building components through thermal and visual imaging. It highlights the need to assess the focus and viewing angle of the images captured. A reflective question prompts consideration of the value in obtaining both visual and thermal images, underlining how visual context improves the understanding of thermal data and boosts overall evaluation accuracy.
- 21.5: SECTION 4- Aerial Thermography
- This page details essential steps for reviewing mission parameters and accepting aerial thermal images during inspections, specifically focusing on verifying planned altitude, sensor specifications, and environmental conditions. It also involves evaluating individual images against standards like focus and coverage. Additionally, a key reflection question stresses the necessity of confirming the field of regard (FoRD) prior to flight to enhance the effectiveness of aerial inspections.
- 21.6: SECTION 5- Thermal Tuning Awareness (Software Review)
- This page covers Task 5.1, focusing on utilizing FLIR Thermal Studio for thermal tuning controls. It outlines actions like adjusting level and span, altering color palettes, and modifying isotherms and spot measurements. It also encourages critical thinking on how these adjustments can influence both data interpretation and visual presentation in thermal analysis.
- 21.7: SECTION 6- Quality Control (QC)
- This page provides a Quality Control (QC) checklist for thermographers, highlighting critical criteria such as focus, thermal contrast, and motion blur prevention. It stresses the significance of QC in ensuring accurate inspection data and emphasizes the need for thorough documentation of environmental conditions and limitations. Additionally, it encourages readers to reflect on the essential role of QC in maintaining data integrity and safety in thermographic inspections.
- 21.8: SECTION 7- Documentation Practice
- This page focuses on creating objective observations from thermal images, highlighting the importance of clarity and objectivity with Level I statements. It provides a format for such observations and includes a boundary check to differentiate between subjective interpretations and factual temperature observations, urging readers to concentrate on observable data without inferring causes.
- 21.9: SECTION 8- Safety and Professional Judgment
- This page emphasizes the importance of responding to unsafe conditions during inspections by stopping work and notifying appropriate personnel. This action prioritizes safety and ensures that hazardous situations are promptly addressed. Continuing work or making adjustments could exacerbate dangers, making immediate communication crucial for assessing risks and implementing safety measures.
