Elements and Performance Criteria

1. Prepare inspection areas for ultrasonic testing
   • Inspection areas are identified, cleaned and prepared for testing using appropriate procedures and materials.
   • Preparation processes are carried out in accordance with the relevant procedures, statutory and OH&S requirements.
   • Inspection areas are visually assessed and obvious discontinuities are identified.
2. Perform ultrasonic testing
   • The most appropriate ultrasonic test for the material/application is selected.
   • Testing equipment is selected and prepared in accordance with standards and/or procedures.
   • Ultrasonic test is carried out in accordance with relevant standards, specifications and OH&S requirements.
   • Ultrasonic testing equipment is checked for defects, and maintained and stored in accordance with procedures, OH&S requirements and manufacturer instructions.
3. Interpret and report the results of ultrasonic tests
   • Indications are assessed and defects are detected and classified in accordance with national and international codes and standards.
   • Defects are confirmed in accordance with enterprise procedures and industry practices.
   • Test results are reported in accordance with enterprise procedures, accepted industry practices and customer service requirements.

Evidence Required

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria required skills and knowledge range statement and the Assessment Guidelines for the Training Package
Overview of assessment	A person who demonstrates competency in this unit must be able to perform ultrasonic testing Competency in this unit cannot be claimed until all prerequisites have been satisfied
Critical aspects for assessment and evidence required to demonstrate competency in this unit	Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria including required knowledge and be capable of applying the competency in new and different situations and contexts
Context of and specific resources for assessment	This unit may be assessed on the job off the job or a combination of both on and off the job Where assessment occurs off the job that is the candidate is not in productive work then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team The assessment environment should not disadvantage the candidate This unit could be assessed in conjunction with any other units addressing the safety quality communication materials handling recording and reporting associated with operating ultrasonic testing equipment and the application of the testing procedure in a range of industrial applications or other units requiring the exercise of the skills and knowledge covered by this unit
Method of assessment	Assessors should gather a range of evidence that is valid sufficient current and authentic Evidence can be gathered through a variety of ways including direct observation supervisors reports project work samples and questioning Questioning techniques should not require language literacy and numeracy skills beyond those required in this unit of competency The candidate must have access to all tools equipment materials and documentation required The candidate must be permitted to refer to any relevant workplace procedures product and manufacturing specifications codes standards manuals and reference materials

Range Statement

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Preparation processes	Surface cleaning and drying
Obvious discontinuities	Observed changes in material homogeneity
Defects	Corrosion, metal fatigue, deformation in non-ferrous/ferrous alloys steels, composite materials, fatigue cracks, stress corrosion cracking, manufacturing defects, thickness measurement and fit, mechanical and bonded repairs, laminar tearing, welding defects and casting defects and/or aircraft components
Reported	Accurate identification of location and size of discontinuities
