Application
This unit of competency defines the skills and knowledge required to perform basic penetrant testing procedures and techniques in a range of metal fabrication and welding trade related industrial applications including fabrications, structures and components across a wide range of industries.
Penetrant testing is performed on critical component or structural zones and actual and potential defects are considered, together with ongoing abnormalities.
This unit should not be selected when unit MEM24022 Undertake penetrant tests has already been selected.
Where interpretation of technical drawings is required unit MEM09002 Interpret technical drawing should also be selected.
Where the selection and use of engineering measurement is required unit MEM12023 Perform engineering measurements should also be selected.
Where the selection and use of industrial chemicals is required unit MEM13003 Work safely with industrial chemicals and materials should also be selected.
Where the selection and use of power tools are required unit MEM18002 Use power tools/hand held operations should also be selected.

Assessment Requirements
Performance Evidence
Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria and include:
following work instructions, standard operating procedures (SOPs) and safe work practices
identifying and interpreting specifications, charts, lists and other reference documentation for performing basic penetrant testing
preparing the area for testing and identifying discontinuities including observed changes in material homogeneity in accordance with procedures
applying test media and carrying out penetrant testing on at least two occasions using techniques appropriate for material/s to be tested, checking and confirming basic indicators and identifying all defects in accordance with procedures
reporting test results in accordance with procedures and customer service requirements on at least two occasions.
Note: Where a volume and/or frequency is not specified, demonstration must be provided at least once.
Knowledge Evidence
Evidence required to demonstrate the required knowledge for this unit must be relevant to and satisfy the requirements of the elements and performance criteria and include knowledge of:

Assessment Conditions
Assessors must:
have vocational competency in performing basic penetrant testing at least to the level being assessed with relevant industry knowledge and experience
satisfy the assessor requirements in the current vocational education and training legislation, frameworks and/or standards.
Where possible, assessment must occur in operational workplace situations. Where this is not possible or where personal safety or environmental damage are limiting factors, assessment must occur in a sufficiently rigorous simulated environment that reflects realistic operational workplace conditions that cover all aspects of workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills.
Conditions for assessment must include access to all tools, equipment, materials and documentation required including relevant workplace procedures, product and manufacturing specifications.
