Application of the Unit
Application of the unit |
In a typical scenario, a technician will be required to monitor a non-ferrous melting and casting operation including tasks undertaken by other employees to ensure that correct quantities are used, correct procedures are followed and product specifications achieved. The unit covers advanced trade skills and knowledge in non-ferrous melting and casting to enable the foundry tradesperson to act as a first line resource to other employees engaged in non-ferrous melting and casting. Work is performed under the overall direction of a metallurgist. Band : B Unit Weight : 4 |

Elements and Performance Criteria Pre-Content
Elements describe the essential outcomes of a unit of competency. |
Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide. |

Evidence Guide
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 |
Evidence should be provided from a number of castings using different alloys and/or different moulds. |
Critical aspects for assessment and evidence required to demonstrate competency in this unit |
Assessors should ensure that candidates can competently and consistently:
|
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
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. |
|
Codes of practice /standards |
Where reference is made to industry codes of practice, and/or Australian/international standards, it is expected the latest version will be used |
Moulds |
Moulds may include sand, die and investment moulds |
Contaminants |
Contaminants include: non-specified metal, rubber, grease, water, paint and non-metallics, closed containers or pipes and pressure containers such as aerosols |
Material specification |
Material specification includes non-ferrous metals and non-ferrous alloys as well as contaminants |
