Elements and Performance Criteria

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. Add any 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.
Where reference is made to industry codes of practice and/or Australian/international standards, the latest version must be used.
Context
This competency unit includes the analysis of equipment components such as screws and dies/tools or items of equipment or processes.
This competency applies to all work environments and sectors within the plastics, rubber and cablemaking industry, but does require both a theoretical/mathematical and a practical analysis of the process at a level equivalent to a screw/die analysis.
Procedures
All operations are performed in accordance with procedures.
Procedures include all relevant workplace procedures, work instructions, temporary instructions and relevant industry and government codes and standards.
These may include:
extrusion
injection
blow moulding.
Tools and equipment
This competency includes use of equipment and tools such as:
measuring equipment (eg micrometers, tapes, verniers, scales)
hand tools
data analysis tools (eg computer programs for data recording and presentation).
Hazards
Typical hazards include:
moving machinery
hot surfaces and products.
Problems
'Anticipate and solve problems' means resolve a wide range of routine and non-routine problems, using product and process knowledge to develop solutions to problems which do not have a known solution/a solution recorded in the procedures.
Typical process and product problems may include:
worn components
validation of new components to design specification
component performance analysis in order to upgrade process performance.
Variables
Key variables to be monitored include:
measurements
machine characteristics.

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 PMBTECH40A Predict polymer properties and characteristics AND PMBORG403B Conduct trails on products or processes, they may be co-assessed 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 ability to apply a understanding of material and process interactions to be able to interpret data and make judgements about the state of the equipment/component
Consistent performance should be demonstrated. For example, look to see that the performance of at least one type of product on a typical machine has been correctly tested and analysed and that there is evidence that other types of analyses can also be achieved.
Assessment method and context
Assessment will occur on industrial equipment in a work-like environment.
Competence in this unit may be assessed:
on an appropriate processing plant requiring demonstration of operation and emergency stop 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.
