Ultrasonics Level 2
PREREQUISITE: Registrants must have successfully completed a Level 1 Ultrasonics course
in accordance with CGSB or SNT-TC-1A requirements.
TRAINING OBJECTIVES: This course is intended to provide a thorough grounding in the
principles of ultrasonic testing and the fundamentals of engineering, materials and components, such
that the technician will be able to:
- identify the suitability of ultrasonic testing for all materials and inspection applications.
- develop inspection techniques and prepare procedures that can be followed by a Level 1 technician.
- document results of the analysis.
- be familiar with all regulatory codes and specifications for ultrasonic testing and their intent.
APPLICABLE STANDARDS: This program meets the requirements of CAN/CGSB-48.9712, ISO 9712 and SNT-TC-1A.
RESPONSIBILITIES OF LEVEL 2 PERSONNEL (as per CGSB): Level 2 personnel are defined
as personnel who perform and/or direct industrial Ultrasonics according to established or
recognized procedures and are responsible for the Ultrasonic method or technique used and for
the interpretation of the test method.
