Unit Descriptor

Unit descriptor 

This unit of competency covers the skills and knowledge required to carry out prescribed chemical analysis and mechanical (destructive) tests on foundry related materials and compare the results against predetermined specifications. It also includes the conducting of optical emission spectroscopy (OES) testing, but not the conducting of any other tests.

Application of the Unit

Application of the unit 

This unit of competency applies to a foundry tradesperson who is required to select and conduct an appropriate chemical, mechanical or OES test from a prescribed range of possible tests. Tests are conducted on samples of materials commonly used in foundries with results being compared against specifications for the material or product. The foundry tradesperson may be required to draw some conclusions from the results of the specified tests in regard to whether an adjustment is required within their skills and knowledge to casting or melting procedures or whether to consult on the results with a metallurgist or other authority according to standard procedures. Work would be conducted under the general supervision of a metallurgist.

Evidence Guide


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 

This competency requires evidence of competency in the selection of appropriate test methods from a prescribed range of tests for various scenarios and the interpretation of test results against predetermined specifications and standards. The scenarios, materials and test results should be relevant to the foundry industry and may be drawn directly from the workplace or may be simulated case studies.

Tests may be conducted in either a workplace or suitable laboratory facility.

Critical aspects for assessment and evidence required to demonstrate competency in this unit 

Assessors should ensure that candidates can competently and consistently:

  • select appropriate test methods
  • obtain repeatable results
  • interpret test results for a foundry
  • successfully complete several scenarios requiring the selection of different tests
  • obtain reproducible test results from testing across different samples requiring different sample preparation/test conditions.

Context of and specific resources for assessment 

Assessment may occur on the job or in an appropriately simulated environment. Access is required to real or appropriately simulated situations, including work areas, materials and equipment, and to information on workplace practices and OHS practices.

Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability.

Access must be provided to appropriate learning and/or assessment support when required. Where applicable, physical resources should include equipment modified for people with disabilities.

Method of assessment 

Assessment must satisfy the endorsed assessment guidelines of the MEM05 Metal and Engineering Training Package.

Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of underpinning knowledge.

Assessment methods must be by direct observation of tasks and include questioning on underpinning knowledge to ensure its correct interpretation and application.

Assessment may be applied under project related conditions (real or simulated) and require evidence of process.

Assessment must confirm a reasonable inference that competency is able not only to be satisfied under the particular circumstance, but is able to be transferred to other circumstances.

Assessment may be in conjunction with assessment of other units of competency where required.

Guidance information for assessment 

Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed.

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.

Standards and industry codes of practice 

Where reference is made to industry codes of practice and/or Australian/international standards, it is expected that the latest version will be used

Prescribed range of tests 

Prescribed range of tests means tests that may be conducted by the foundry tradesperson and where the need for the test has been determined by a metallurgist or other authority according to the procedures of the enterprise and the requirements for the casting and mould materials being used and the product being cast. The prescribed range of tests may include:

  • OES
  • tensile/compression testing which may include testing for tensile strength, compressive strength, elongation, reduction of area, yield stress, yield point, proof stress, Young's modulus, elastic/plastic region and deformation or viscoelastic deformation
  • hardness testing - Vickers, Brinell, Rockwell and Durometer tests
  • impact testing including Izod, Charpy and Dropweight Tear

  • fatigue/flex testing
  • creep testing
  • strain test and measurement
  • static shear and bend test

  • infrared spectroscopy (IR)
  • gas chromatography (GC)
  • X-ray fluorescence (XRF)
  • flame photometry
  • atomic absorption spectrometry (AAS)
  • scanning electron microscopy (SEM)

Prepare sample 

Prepare sample means that:

  • representative sub-samples have been taken
  • samples are ground and milled
  • the sample is ready for the test

Prepare instrument includes:

  • checking calibration
  • ensuring the availability of required consumables
