Unit of competency details

Unit descriptor 

This unit of competency covers the analysis of the performance, and performance verification of existing equipment. It is based on PMBTECH501A Analyse equipment performance .

It involves calculating the theoretical performance components, gathering data, calculating performance and making recommendations based on verification results.

Application of the unit 

This unit of competency applies to technicians who are responsible for setting up and operating performance verification trials and analysing the results to determine actual performance compared to theoretical performance of equipment and equipment components.

It applies typically to the extrusion, automated casting or moulding sectors of the industry. This competency applies to all work environments and sectors within the industry, but does require both a theoretical/mathematical and a practical analysis of the process at a level equivalent to an analysis of screw performance in an extruder.

The competency does not require knowledge of industry sectors and materials other than that in which the technician works. It assumes an understanding of the operation of all relevant equipment and processes but does not necessarily require them to be used personally.

This competency is typically performed by a senior technician who will take the lead in the data gathering phase and then analyse the data.

Prerequisite units 

Employability skills 

This unit contains employability skills.

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.

REQUIRED SKILLS AND KNOWLEDGE 

This section describes the skills and knowledge required for this unit.

Required skills 

Required skills include the ability to:

• predicting the interactions of the materials, equipment and process and their impacts on performance
• implementing the enterprise's procedures and policies within appropriate time constraints and in a manner relevant to the job
• high levels of numeracy and literacy to interpret technical specifications and reports
• advanced numeracy allowing the calculation and interpretation of statistics, product formulae and process conditions
• identifying hazards associated with the trial and implementing controls by applying the hierarchy of control

Required knowledge 

Required knowledge includes:

• enterprise requirements
• calculation of equipment and component performance from the design specification
• determine equipment and design performance from practical trials
• determine the 'limiting component' in the performance of an item of equipment or a process
• determine possible performance of an item of equipment/process if practical improvements were made to the 'limiting item'

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 

The unit will be assessed in as holistic a manner as is practical and may be integrated with the assessment of other relevant units of competency.

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

Competence must be demonstrated in the ability to recognise and analyse potential situations requiring action and then in implementing appropriate corrective action.

Consistent performance should be demonstrated. In particular look to see that:

• a thorough understanding of process materials, their additives and the rheological, heat and other effects of processing to the design of equipment and components are applied to predict practical performance results
• material and process interactions should also understood and able to be applied to interpreting data and making judgements about the state of the equipment/component.

Context of and specific resources for assessment 

Assessment will require access to an operating plant over an extended period of time, or a suitable method of gathering evidence of operating ability over a range of situations.

Assessment will occur over a range of situations which will include disruptions to normal, smooth operation.

Simulation or case studies/scenarios may be required to allow for timely assessment of parts of this unit of competency. Simulation should be based on the actual plant and will include 'walk-throughs' of the relevant competency components. A bank of scenarios/case studies/what ifs and questions will be required to probe the reasoning behind observable actions.

Method of assessment 

It may be appropriate to assess this unit concurrently with relevant teamwork and communication units.

It may be appropriate to assess this unit concurrently with other relevant units.

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
