Knowledge and ability to identify and take appropriate action on the range of possible causes of product faults.
Language , literacy and numeracy requirements
This unit requires the ability to read and interpret typical product specifications, job sheets, material labels, and machine control panels such as those displaying PLC information, if fitted.
Writing is required to the level of completing workplace forms, quality assurance records and production reports.
Numeracy is required to the level of determining required weights/volumes of materials in a resin mix for different circumstances (say using a data sheet), number of layers of impregnated matrix required to yield the required product laminate thickness, and similar activities.
Evidence Guide
The Evidence Guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, the range statement and the assessment guidelines for this training package.
Overview of assessment
A holistic approach should be taken to the assessment.
Assessors must be satisfied that the person can consistently perform the unit as a whole, as defined by the Elements, Performance Criteria and skills and knowledge.
Where the assessee does not currently possess evidence of competency in PMBPROD294B Operate resin transfer moulding equipment , it may be co-aassessed with this unit.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
It is essential that competence is demonstrated in the knowledge and skills defined in this unit. These may include the ability to:
- identify critical materials properties and composites moulding process characteristics in relation to the process requirements and the end product
- identify and take appropriate action on problems and potential problems.
Consistent performance should be demonstrated. For example, look to see that:
- the process runs smoothly , with the minimum need for intervention
- all safety procedures are always followed.
Assessment method and context
Assessment will occur on an industrial resin transfer moulding equipment and will be undertaken in a work-like environment.
Competence in this unit may be assessed:
- using appropriate resin transfer moulding equipment requiring demonstration of start-up, operation and shutdown procedures
- in a situation allowing for the generation of evidence of the ability to recognise, anticipate and respond to problems
- by using a suitable simulation and/or a range of case studies/scenarios
- through a combination of these techniques.
In all cases it is expected that practical assessment will be combined with targeted questioning to assess the underpinning knowledge and theoretical assessment will be combined with appropriate practical/simulation or similar assessment. Assessors need to be aware of any cultural issues that may affect responses to questions.
Assessment processes and techniques must be culturally appropriate and appropriate to the oracy, language and literacy capacity of the assessee and the work being performed.
Specific resources for assessment
This section should be read in conjunction with the Range Statement for this unit of competency. Resources required include suitable access to an operating plant or equipment that allows for appropriate and realistic simulation. A bank of case studies/scenarios and questions will also be required to the extent that they form part of the assessment method. Questioning may take place either in the workplace, or in an adjacent, quiet facility such as an office or lunchroom. No other special resources are required.
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.
