What an assessment for MEM24035 must cover

39 assessable components: 4 elements (18 performance criteria), 6 performance evidence and 15 knowledge evidence requirements. An audit-defensible tool maps every question and task back to these — that mapping is the coverage matrix Auditori generates alongside the assessment.

Elements & performance criteria

1 Establish job requirements

1.1Comply with relevant WHS and regulatory requirements, standards, codes of practice and standard operating procedures (SOPs) for eddy current array testing
1.2Identify job requirements from specifications, job sheets or work instructions

2 Prepare for testing

2.1Liaise with client to explain testing requirements and schedule tests
2.2Use established safe work practices and personal protective equipment (PPE) in accordance with SOPs
2.3Identify inspection areas and determine if special access requirements appropriate for the NDT test need to be communicated to the client
2.4Clean and prepare for testing using appropriate procedures and materials
2.5Assess inspection areas visually and identify obvious discontinuities

3 Conduct eddy current array tests

3.1Select the most appropriate eddy current array test technique for the material or application
3.2Select test equipment and appropriate probe type and shape
3.3Conduct reference calibration in accordance with relevant standards, codes and/or procedures
3.4Optimise test set up by calculating effects on probe dimensions, frequency and phase of induced field and material conductivity on eddy current penetration
3.5Conduct eddy current test(s) in accordance with relevant standards, codes, work instructions and WHS requirements
3.6Store and maintain eddy current array testing equipment in accordance with SOPs and WHS requirements

4 Interpret and report results of eddy current array tests

4.1Review conduct of the test and confirm test procedures were applied correctly
4.2Monitor scans and assess indications for discontinuities, defects and other data required in test report
4.3Apply acceptance criteria to discontinuities to detect defects
4.4Classify defects in accordance with test specification and relevant standards
4.5Report test results and complete all job records in accordance with relevant standards, test specifications and workplace procedures

Performance evidence

review eddy current array test specifications on at least two different specimens and identify: o relevant Australian and/or international standards o material test area o most appropriate eddy current array test technique and equipment o workplace access and WHS requirements for specified eddy current tests
set up, calibrate and perform eddy current array tests on at least two different specimens to identify: o weld discontinuities and cracks o material conductivity o coating thickness o tube conformance to specifications
interpret eddy current array test data from the above tests to identify: o material thickness o corrosion o discontinuities o conductivity o non-conductive coating thickness on coated metal plate and tube
apply acceptance criteria to discontinuities and classify defects in accordance with national and international standards
calculate the effect of probe lift on the amplitude and phase of test material
prepare test reports in accordance with standards and test specifications and workplace procedures.

Questions about assessing MEM24035

What does an assessment tool for MEM24035 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MEM24035 needs to address all 39 unit components: 4 elements with 18 performance criteria, 6 performance evidence requirements, 15 knowledge evidence requirements, and the foundation skills. A coverage matrix mapping each question and task to these components is what an auditor looks for.

How does Auditori generate an assessment tool for MEM24035?

Auditori pulls the current release of MEM24035 from training.gov.au and generates a complete package: candidate assessment, assessor guide with model answers and observation criteria, and a coverage matrix mapping every component. A suitably qualified person then reviews and approves the draft in a built-in workflow — consistent with ASQA's guidance on AI use in VET — before export as branded PDF and editable Word.

Is the first assessment tool really free?

Yes. Every new account includes one free credit — enough to generate the complete assessment tool for MEM24035 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing MEM24035 assessment instead of generating a new one?

Yes — upload your existing assessment or learner guide and Auditori maps it against every element, performance criterion, PE and KE of MEM24035, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
