Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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.

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 rubber vulcanising process characteristics in relation to the process requirements and the end product

make adjustment 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 human intervention

all safety procedures are always followed.

Assessment method and context

Assessment will occur on an industrial autoclave and will be undertaken in a work-like environment.

Competence in this unit may be assessed:

on anappropriate operating plant 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.


Submission Requirements

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

This describes the essential skills and knowledge and their level required for this unit.

Application of knowledge of the materials, equipment and process sufficient to recognise material and equipment conditions which may lead to out of specification production. For example,

A knowledge of organization procedures, quality requirements at each stage of production stage and relevant regulatory requirements along with the ability to implement them within appropriate time constraints and work standards.

Application of the knowledge of managing risks using the hierarchy of controls applied to the vulcanising process. Application of approved hazard control and safety procedures and the use of PPE in relation to handling materials, equipment operation and cleanup.

Skill to identify the range of possible causes of product faults.

Knowledge as a basis for solving processing and material problems including:

characteristics of materials and behaviour in relation to heat, thickness and cure rates.

identify the function of vulcanising equipment, components and the materials used

changes to materials at various stages of production

relationship between steam pressure and temperatures and the effects this and time will have on product quality and production output

impact of heat and pressure in relation to providing strength, stiffness, resistance to deformation, fatigue and abrasion

monitor equipment operation and product quality

impact of product section/thickness on cure requirements

impact of compound cure system on cure requirements

impact of heating too quickly/slowly on final product properties

compound properties and their interactions with process conditions

relationships between compound properties and process conditions

changes to compound properties to better suit process requirements

product problems related to compound properties

product problems related to process conditions

adjustments to process conditions to meet compound and product requirements.

Competence also includes the ability to:

plan own work, including predicting consequences identifying improvements

maintain output and product quality using appropriate instruments, controls checks, test information and readings

identify and describe own role and the roles of others involved directly in the vulcanising process

identify when assistance is required to solve problems

identify factors which may affect product quality and production output and appropriate remedies.

Language, literacy and numeracy requirements

This unit requires the ability to read and interpret typical product specifications, job sheets and material labels as provided to operators.

Writing is required to the level of completing workplace forms, quality assurance records and production reports.

Basic numeracy is also required, eg to determine required steam pressure to give necessary time/temperature cycle.

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.
