An NDE technician may conduct visual testing directly or indirectly. While direct visual testing
gives the technician an uninterrupted line of sight to the test object, indirect visual testing
requires the use of visual aids to achieve a line of sight to the test object.

• List the basic techniques used in visual testing
• Understand the differences between direct and indirect visual testing
