- MEM24003B - Perform basic magnetic particle testing
Perform basic magnetic particle testing
This unit applies to portable and fixed ('yoke' or 'bench') basic magnetic particle testing techniques on fabrications, structures and components across a wide range of industries.
The work can relate to scheduled and unscheduled maintenance activities using general tools and specific magnetic testing equipment as specified in maintenance documentation, testing procedures or operator instructions.
Actual and potential defects are considered, together with ongoing abnormalities in fabrications, components and structures. Magnetic particle testing is performed on critical component or structural zones. All testing must be completed with particular attention to personal safety and OH&S regulations. Certification against Australian standards may be achieved where assessment in this unit of competency is carried out in conjunction with an examining authority as described in ISO 9712.
Materials and chemicals which are subject to codes and regulations - for example, chemicals, explosives, solvents, dangerous materials, acids, or noxious waste products - must be subject to safe work habits and must be stored and used in accordance with safe work practices.
This unit should not be selected when Unit MEM24004B (Perform magnetic particle testing) has already been selected.
Where power tools are required, Unit MEM18002B (Use power tools/hand held operations) should also be selected.
Where tests require the interpretation of drawings, Unit MEM09002B (Interpret technical drawings) should also be selected.
Unit Weight: 2
Use hand tools
Elements and Performance Criteria

1.2. Preparation processes are carried out in accordance with the relevant specifications and OH&S requirements.
1.3. Inspection areas are visually assessed and obvious discontinuities are identified.
2. Perform basic magnetic particle testing
2.1. Nominated 'yoke' or 'bench' magnetic particle testing procedure is identified from standard operating procedures.
2.2. Test equipment is prepared in accordance with relevant standards and/or procedures.
2.3. Magnetic particle test is carried out in accordance with relevant work instructions and OHS requirements.
2.4. Magnetic particle testing equipment is maintained and stored in accordance with standard operating procedures and OH&S requirements.
3. Report the results of magnetic particle test(s)
3.1. Basic indications are checked and defects are identified in accordance with enterprise standards and/or procedures.
3.2. Basic indications are confirmed in accordance with enterprise standards and/or procedures.
3.3. Test results are reported in accordance with enterprise standards and/or procedures.
Look for evidence that confirms skills in:
interpreting and following procedures
identifying inspection areas
identifying discontinuities and defects
selecting appropriate testing techniques and procedures
entering routine and familiar information onto proformas and standard workplace forms
locating, reading and interpreting information on written job instructions, specifications, charts, lists and other reference documentation
planning, sequencing operations
Look for evidence that confirms knowledge of:
procedures and OH&S requirements in relation to the preparation process
established assessment procedures and techniques
types of discontinuities and their consequences
scope and basic principles of magnetic particle testing
procedure for carrying out magnetic particle test using either the 'yoke' or 'bench'
advantages and limitations of magnetic particle testing
hazards and safety precautions associated with magnetic particle testing
basic maintenance and storage procedures for testing equipment
common basic defects
methods/procedures for reporting test results
advantages, limitations of various equipment
magnetic particle application - methods for wet, dry particles
recording and reporting results of simple tests
safety precautions in testing

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 basic magnetic particle 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 performing basic magnetic particle testing procedures 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, supervisor's 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.
Guidance information for assessment
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.
Surface cleaning and drying
This unit contains employability skills.
