MEM04023
Undertake prescribed tests on foundry-related materials


Application

This unit of competency defines 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. This work is performed under the overall direction of a metallurgist.

The foundry tradesperson may be required to draw some conclusions from the results of the specified tests regarding 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.

Where the interpretation of technical drawings is required unit MEM09002 Interpret technical drawing should also be selected.

Where the selection and use of engineering measuring equipment is required unit MEM12023 Perform engineering measurements should also be selected.

Where the selection and use of tools is required unit MEM18001 Use hand tools and unit MEM18002 Use power tools/hand held operations, should also be selected as appropriate.

No licensing, legislative or certification requirements apply to this unit at the time of publication.
