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 applies to the operation of all calendering within the plastics and rubber industries. It also includes the operation of all relevant additional equipment, where that equipment is integral to the calendering process.
It includes the calendering of 'solid' polymers as well as the coating/impregnating of fabric, wire and other webs.
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.
Tools and equipment
This unit of competency includes use of equipment and tools such as:
calenders
additional equipment (such as mill knives, thickness gauges, profiling gauges/tools/jigs, nip adjusting bars, strainers and metal detector)
manual handling equipment
product take up equipment
material feeding equipment
hoists/lifting equipment not requiring any special permits or licences
basic hand tools
relevant personal protective equipment.
Hazards
Typical hazards include:
restricted spaces
heat
hazardous chemicals
dust/fumes
manual handling hazards
knife hazards
nip hazards
creel and spooling hazards.
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:
contamination of materials
incorrect machine set-up, especially the nip setting tensions
temperatures
uniformity of product.
Appropriate action for problems outside area of responsibility may be reporting to an appropriate person.
Appropriate action for solving problems within area of responsibility includes asking questions and seeking assistance from appropriate persons/ sources.
Variables
Key variables to be monitored include:
operating temperatures
speed
nip settings
materials consistency
surface finish
product integrity and general conformance to specifications.

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 PMBPROD207A Operate calender, it 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 knowledge and skills defined in this unit. These may include the ability to:
identify critical materials properties and calendering process variables in relation to the process requirements and the end product
make adjustments to the process as required
identify and take appropriate action on problems and potential problems.
Consistent performance should be demonstrated. For example, look to see that:
the process runs consistently and smoothly, with the minimum need for intervention
all safety procedures are followed.
Assessment method and context
Assessment will occur on a calendering equipment and will be undertaken in a work-like environment.
Competence in this unit may be assessed:
by using an appropriate calendering machine requiring demonstration of start-up, operation and shutdown procedures
in a situation allowing for the generation of evidence of the ability to 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.
